Conclusion:
By completing this lecture and lab, you will have gained important foundational skills in Python programming for Windows administration, specifically in managing files and directories. Understanding these core concepts is essential for any system administrator working within a Windows environment.
Below are the Python scripts for the file and directory operations, including detailed comments:
Python Script for File Operations:
```python
# Write a Python script to create a new text file and write a few lines of text to it.
# Import the os module for file operations
import os
# File creation and writing
def create_and_write_file(filename, content):
# Open the file in write mode ('w')
with open(filename, 'w') as file:
# Write the content to the file
file.write(content)
# Specify the file name and content
file_name = 'sample_file.txt'
file_content = "Hello, this is a sample text file.\nThis file is created using Python."
# Call the function to create and write to the file
create_and_write_file(file_name, file_content)
print(f"File '{file_name}' has been created and written to.")
# Write another script that reads from the created file and prints its contents to the console.
# File reading
def read_file_contents(filename):
# Open the file in read mode ('r')
with open(filename, 'r') as file:
# Read and print the file contents
file_contents = file.read()
print(f"Contents of '{filename}':\n{file_contents}")
# Call the function to read and print file contents
read_file_contents(file_name)
```
Python Script for Directory Operations:
```python
# Write a script to create a new directory and verify its creation using Python.
# Import the os module for directory operations
import os
# Directory creation
def create_directory(directory_name):
# Define the path for the new directory
path = os.path.join(os.getcwd(), directory_name)
# Create the directory
os.mkdir(path)
return path
# Specify the directory name
new_directory = 'test_directory'
# Call the function to create the directory
directory_path = create_directory(new_directory)
print(f"Directory '{new_directory}' has been created at: {directory_path}")
# Create another script to list all the files and subdirectories within a specified directory.
# Import the os module for directory listing
import os
# Directory listing
def list_files_and_subdirectories(directory_path):
# List all files and subdirectories in the specified directory
contents = os.listdir(directory_path)
print(f"Contents of directory '{directory_path}':\n{contents}")
# Call the function to list contents of the directory
list_files_and_subdirectories(directory_path)
```
Python Script for Advanced Task (Optional):
```python
# Implement a script that recursively traverses a directory structure and identifies all text files within it.
import os
# Recursive directory traversal
def identify_text_files(directory_path):
text_files = []
for root, dirs, files in os.walk(directory_path):
for file in files:
if file.endswith('.txt'): # Identify text files
text_files.append(os.path.join(root, file))
return text_files
# Specify the directory path for traversal
specified_directory = 'specified_directory'
# Call the function to identify text files within the specified directory
text_files_in_directory = identify_text_files(specified_directory)
print(f"Text files within directory '{specified_directory}':\n{text_files_in_directory}")
```
These scripts demonstrate file and directory operations in Python, utilizing built-in functions from the os module. Each script is thoroughly commented to explain the purpose and functionality of each code block.
Focus on a mix of theory and hands-on exercises that engage the students and convey practical skills they can apply in real-world scenarios.

Hands-on labs should be prepared in advance, and you should ensure that each student or group has access to a Windows Server environment for the practical exercises.
Creating drill exercises for Python beginners is a great way to build foundational skills. These exercises will focus on variables, variable comparisons, conditional statements (if-then, switch-case), loops (for and while), and defining functions (def modules). Let's get started:
### Exercise 1: Variables and Variable Comparisons
**Objective**: Understand how to create variables and perform basic comparisons.
1. Create two variables, `a` and `b`, assign numeric values to them.
2. Write a Python script to check if `a` is greater than `b` and print the result.
3. Modify the script to check if `a` is equal to `b` and print the result.
### Exercise 2: If-Then Statements
**Objective**: Learn how to use if-then statements for decision-making.
1. Create a variable `temperature` and assign a numeric value.
2. Write an if-then statement that prints "It's a hot day" if `temperature` is greater than 30, otherwise prints "It's not a hot day".
### Exercise 3: Switch-Case Using Dictionary
**Objective**: Python doesn't have a built-in switch-case statement, but you can mimic one using dictionaries.
1. Create a dictionary `day_of_week` that maps numbers to their corresponding day names (e.g., 1: "Monday").
2. Take a variable `day_number` and assign it a number between 1 and 7.
3. Use the dictionary to print the corresponding day of the week.
### Exercise 4: For and While Loops
**Objective**: Understand how to use for and while loops for iteration.
1. Create a list of five numbers.
2. Write a for loop to iterate over the list and print each number.
3. Write a while loop that keeps printing numbers from the list as long as they are less than 10.
### Exercise 5: Defining and Using Functions
**Objective**: Learn how to define and call functions.
1. Define a function named `add_numbers` that takes two parameters and returns their sum.
2. Call this function with two numbers of your choice and print the result.
3. Modify the function to take an optional third parameter, add it to the sum if it is provided.
**Instructions for Students**
- Each exercise is designed to build upon the last, reinforcing concepts along the way.
- Try to complete each exercise without looking at solutions. Struggling through the process is a key part of learning.
- After completing each exercise, experiment by modifying the code to see what changes.
- Feel free to collaborate with peers for troubleshooting and learning but ensure to do the coding yourself.
These exercises will lay the groundwork for more complex Python programming, particularly geared towards system administration tasks. Remember, practice and experimentation are essential in learning to code.
I'll provide the solution code for each of the drill exercises:
### Exercise 1: Variables and Variable Comparisons
```python
# Exercise 1 Solution
# Creating variables
a = 10
b = 5
# Checking if a is greater than b
if a > b:
print("a is greater than b")
else:
print("a is not greater than b")
# Checking if a is equal to b
if a == b:
print("a is equal to b")
else:
print("a is not equal to b")
```
### Exercise 2: If-Then Statements
```python
# Exercise 2 Solution
# Creating the temperature variable
temperature = 35
# If-then statement
if temperature > 30:
print("It's a hot day")
else:
print("It's not a hot day")
```
### Exercise 3: Switch-Case Using Dictionary
```python
# Exercise 3 Solution
# Creating the day_of_week dictionary
day_of_week = {
1: "Monday",
2: "Tuesday",
3: "Wednesday",
4: "Thursday",
5: "Friday",
6: "Saturday",
7: "Sunday"
}
# Assigning a number to day_number
day_number = 4
# Printing the day of the week
print(day_of_week.get(day_number, "Invalid day number"))
```
### Exercise 4: For and While Loops
```python
# Exercise 4 Solution
# Creating a list of numbers
numbers = [3, 7, 2, 9, 12]
# For loop to iterate and print each number
for number in numbers:
print(number)
# While loop to print numbers less than 10
index = 0
while index < len(numbers):
if numbers[index] < 10:
print(numbers[index])
index += 1
```
### Exercise 5: Defining and Using Functions
```python
# Exercise 5 Solution
# Defining the add_numbers function
def add_numbers(num1, num2, num3=None):
if num3:
return num1 + num2 + num3
else:
return num1 + num2
# Calling the function with two parameters
result = add_numbers(4, 5)
print(result)
# Calling the function with three parameters
result = add_numbers(4, 5, 6)
print(result)
```
These solutions align with the objectives of each exercise and demonstrate the basic constructs of Python programming. Remember, there can be multiple ways to achieve the same result in programming, so students are encouraged to experiment and find their unique solutions.

Creating a Python script for Windows Server administration tasks like creating users, assigning them to groups, and displaying their permissions requires administrative privileges and access to the Windows Server. For this task, we can use Python's `subprocess` module to execute PowerShell commands, which are commonly used for Windows administration.
Before proceeding, ensure Python is installed on the Windows Server and you have administrative privileges. This script will:
1. Create 5 users on the Windows Server.
2. Assign them to a group (for simplicity, let's use an existing group, like 'Users').
3. Display the users with their group memberships.
### Python Script for Windows Server Administration
```python
import subprocess
def run_powershell_command(command):
"""Executes a PowerShell command from Python."""
completed_process = subprocess.run(["powershell", "-Command", command], capture_output=True, text=True)
return completed_process.stdout.strip()
def create_user(username):
"""Creates a new user on the Windows Server."""
command = f"New-LocalUser -Name '{username}' -NoPassword"
return run_powershell_command(command)
def add_user_to_group(username, groupname):
"""Adds a user to a specified group."""
command = f"Add-LocalGroupMember -Group '{groupname}' -Member '{username}'"
return run_powershell_command(command)
def get_user_group_membership(username):
"""Gets the groups that the user is a member of."""
command = f"Get-LocalGroupMember | Where-Object {$_.Name -like '*{username}*'}"
return run_powershell_command(command)
# List of users to create
users = ["User1", "User2", "User3", "User4", "User5"]
group = "Users"
# Creating users and adding them to the 'Users' group
for user in users:
create_user(user)
add_user_to_group(user, group)
print(f"Created user {user} and added to group {group}.")
# Displaying user group memberships
print("\nUser Group Memberships:")
for user in users:
groups = get_user_group_membership(user)
print(f"{user} is a member of: {groups}")
```
### How to Run the Script
1. Save the script as a `.py` file, e.g., `user_admin.py`.
2. Run the script using Python from an administrative command prompt.
### Important Notes
- This script uses the `New-LocalUser` and `Add-LocalGroupMember` PowerShell cmdlets, which are available on Windows Server 2019.
- Error handling and detailed permissions settings are not included in this basic script.
- Be cautious with scripts that make changes to user accounts and groups. Always test in a safe environment before running on a production server.
- The script assumes the existence of the 'Users' group. If you want to create and use a different group, modify the script accordingly.
This script serves as a starting point for automating Windows Server administrative tasks using Python. As you grow in Python and Windows administration, you can expand this script's capabilities to suit more complex requirements.
To perform the same tasks of creating users, assigning them to groups, and viewing their group memberships using the Windows Server 2019 GUI, follow these steps:
### 1. Creating Users
1. **Open Server Manager**: Click on the Start menu and select 'Server Manager'.
2. **Open Tools Menu**: In the Server Manager dashboard, click on 'Tools' in the top-right corner.
3. **Access Computer Management**: Select 'Computer Management' from the drop-down menu.
4. **Navigate to Local Users and Groups**: In the Computer Management window, expand 'System Tools', then expand 'Local Users and Groups'.
5. **Create New User**: Right-click on 'Users' and select 'New User...'.
6. **Fill User Details**: A dialog box appears. Enter the new user's details, such as User name, Full name, and Description. Set a password for the user. You can also choose various options like 'User must change password at next logon'. Click 'Create' when done. Repeat for each user you wish to create.
### 2. Assigning Users to a Group
1. **Access Local Groups**: In the 'Local Users and Groups' section, click on 'Groups'.
2. **Select a Group**: Find and double-click the group you want to add users to (e.g., 'Users').
3. **Add User to Group**: In the group's properties window, click 'Add…'.
4. **Enter User Name**: Type the name of the user you want to add, then click 'Check Names' to verify the username. Click 'OK' once the correct user is found.
5. **Confirm and Close**: Click 'Apply' or 'OK' to add the user to the group. Repeat for each user.
### 3. Viewing User Group Memberships
1. **View User Properties**: Go back to the 'Users' folder under 'Local Users and Groups'.
2. **Open User Properties**: Right-click on a user and select 'Properties'.
3. **Check Group Memberships**: In the user's properties window, navigate to the 'Member Of' tab. This tab shows all the groups that the user is a member of.
4. **Close Properties**: Once done, click 'OK' or 'Cancel' to close the properties window. Repeat for each user to view their group memberships.
### Comparing GUI and Python Script Methods
- **Ease of Use**: The GUI method is more intuitive for users not familiar with scripting or command-line tools.
- **Repetitive Task Handling**: For creating multiple users, the GUI method can be time-consuming and repetitive. The Python script automates this process, saving time.
- **Error Margin**: GUI operations reduce the chance of syntax errors common in scripting but can be prone to user input errors.
- **Scalability**: The Python script is more scalable for large-scale operations, like creating hundreds of users.
- **Learning Curve**: The GUI is straightforward for beginners, while the Python script requires basic knowledge of Python and PowerShell commands.
In summary, the GUI method in Windows Server 2019 is user-friendly and straightforward for performing basic tasks like creating users and managing groups. However, for larger scale operations and automating repetitive tasks, scripting with Python provides a more efficient and scalable solution.
