Python Comments

banner-python

In Python 3, comments are super useful for explaining your code—like sticky notes to your future self or teammates. Here's how to do both single-line and multi-line comments:

📝 Single-line Comments​

Use the # symbol. Everything after # on that line is ignored by Python.

# This is a single-line comment
print("Hello, World!")  # This prints a greeting

📝 Multi-line Comments (Two Options)​

Option 1: Multiple # lines (most common and recommended)​

# This is a multi-line comment
# written across several lines.
# Each line starts with a '#'.
print("This works great!")

Option 2: Triple Quotes (''' or """) — a sneaky workaround​

Technically, triple quotes create a multi-line string, but if it's not assigned to anything, Python ignores it. So, it's used like a comment:

'''
This is a multi-line comment
using triple quotes.
Not technically a comment, but it works.
'''
print("Still works fine!")

"""
This is another way using double quotes.
Used for multi-line docstrings too.
"""

⚠️ Note: Use triple quotes for docstrings (i.e., documentation for functions/classes), and # for real comments. Triple-quoted "comments" are still technically strings, so overuse may affect performance slightly in large scripts.
