Configuration management and version control in Software Engineering - Mini Project: Build & Apply

Configuration Management and Version Control Basics

📖 Scenario: You are working on a small software project with a team. To keep track of changes and manage different versions of your files, you need to understand configuration management and version control.This project will guide you through the basic concepts by simulating a simple version control setup using a dictionary to represent files and their versions.

🎯 Goal: Build a simple data structure to represent files and their versions, add a configuration setting for version threshold, filter files based on version, and finalize the version control summary.

📋 What You'll Learn

Create a dictionary named files with file names as keys and version numbers as values.

Add a variable named version_threshold to set the minimum version number to consider.

Use a dictionary comprehension named updated_files to select files with versions greater than or equal to version_threshold.

Add a final key-value pair 'summary': 'Version control setup complete' to the updated_files dictionary.

💡 Why This Matters

🌍 Real World

Software teams use configuration management and version control to track changes, avoid conflicts, and maintain project history.

💼 Career

Understanding these basics is essential for developers, testers, and project managers to collaborate effectively and maintain software quality.

1

Create the initial files dictionary

Create a dictionary called files with these exact entries: 'README.md': 1, 'app.py': 3, 'config.yaml': 2, 'requirements.txt': 1.

Software Engineering

# Create the files dictionary with exact file names and versions
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with the given file names as keys and version numbers as values.

2

Add a version threshold variable

Add a variable called version_threshold and set it to 2.

Software Engineering

files = {'README.md': 1, 'app.py': 3, 'config.yaml': 2, 'requirements.txt': 1}
# Set the version threshold to 2
# Your code here

Need a hint?

Simply assign the number 2 to the variable version_threshold.

3

Filter files by version using dictionary comprehension

Create a dictionary comprehension called updated_files that includes only files from files with version numbers greater than or equal to version_threshold.

Software Engineering

files = {'README.md': 1, 'app.py': 3, 'config.yaml': 2, 'requirements.txt': 1}
version_threshold = 2
# Create updated_files dictionary with files having version >= version_threshold
# Your code here

Need a hint?

Use a dictionary comprehension with for file, version in files.items() and an if condition to filter.

4

Add a summary entry to the updated_files dictionary

Add a new key-value pair to updated_files with key 'summary' and value 'Version control setup complete'.

Software Engineering

files = {'README.md': 1, 'app.py': 3, 'config.yaml': 2, 'requirements.txt': 1}
version_threshold = 2
updated_files = {file: version for file, version in files.items() if version >= version_threshold}
# Add summary key to updated_files
# Your code here

Need a hint?

Use the syntax updated_files['summary'] = 'Version control setup complete' to add the new entry.
