Comments in Python

 

📝 What are comments in Python?

Comments are lines in code that are ignored by the interpreter.
They are used to explain code for humans.

 1. Single-line comments

Use #

# This is a comment

print("Hello")  # This is also a comment

✔ Used for short explanations
✔ Most common type

2. Multi-line comments (not official, but used)

Python doesn’t have real multi-line comment syntax like other languages.

Method 1: Multiple #

# This is line 1
# This is line 2
# This is line 3

Method 2: Triple quotes (doc-style, not true comments)

"""

This looks like a comment

but actually it's a string

"""

⚠ This works only if not assigned to a variable (otherwise it's a string).

3. Docstrings (special comments for documentation)

Used inside functions, classes, modules:

def add(a, b):

    """This function returns sum of two numbers"""

    return a + b
