Understanding code metrics is crucial for maintaining high-quality code. This tool analyzes your code snippet and calculates key values:

• Total Lines: The overall number of lines in the code.
• Blank Lines: Lines that are empty or contain only whitespace. These may indicate formatting or readability styles.
• Comment Lines: Lines that include comments. Comments are essential for documentation, but an excess may also indicate redundancy.
• Code Lines: Lines that contain actual code (Total Lines minus Blank and Comment Lines). This provides insight into the effective code content.

These metrics are useful for:

• Identifying opportunities for code refactoring.
• Ensuring sufficient documentation and readability.
• Estimating maintenance complexity.
• Comparing code density between modules.

Example: Consider the following Python snippet:

# This is a sample function
def add(a, b):
    # Return the sum of a and b
    return a + b

# Another comment line
    

The tool might output:

Total Lines: 7
Blank Lines: 0
Comment Lines: 3
Code Lines: 4
    

These metrics offer a snapshot of your code's composition, helping in refactoring, performance tuning, and maintaining clean code practices.
