1. Python Comments
Understanding Single-line and Multi-
line Comments and Their Uses

2. What are Comments in Python?
•• Comments are lines in code that are not
executed by the Python interpreter.
•• They are used to explain code, make it more
readable, and help others understand the
logic.
•• Comments can be single-line or multi-line.

3. Single-line Comments
•• Begin with the hash symbol (#).
•• Everything written after # on that line is
ignored by Python.
•• Used for short explanations or notes.
•Example:
•# This is a single-line comment
•print('Hello World') # This prints a message

4. Multi-line Comments
•• Python does not have a specific syntax for
multi-line comments.
•• You can use triple quotes (''' or """) to write
multiple lines of comments.
•• Commonly used for explaining large sections
of code or documentation.
•Example:
•'''
•This is a multi-line comment.
•It can span across multiple lines.
•'''
•print('Python Comments Example')

5. Uses of Comments
•• Explain the purpose of code.
•• Make debugging and maintenance easier.
•• Help new developers understand existing
code.
•• Temporarily disable code during testing.
•• Add documentation for functions or scripts.

6. Best Practices for Writing
Comments
•• Keep comments short and meaningful.
•• Update comments when changing code.
•• Avoid obvious comments.
•• Use comments to clarify complex logic.
•• Maintain a consistent style throughout the
code.
