Python Comments

Comments are notes for humans. Python ignores them while running. One line starts with #. Write why, not “x = 1 assigns 1”. Obvious code plus a noisy comment looks like copy-paste notes.

A docstring is """...""" right under def or class. help(fn) shows it. Several # lines can explain a tricky block. Don’t confuse a triple-quoted string in the middle of code with a real docstring — placement under def/class matters.

Python Comments — output — 72. The # lines do not print.

Exam tip

Comment vs docstring in one sentence each.

Example

# Comments
# marks out of 100
marks = 72
print(marks)  # real print

Python Comments — output: 72. The # lines do not print.

Short notes

Def# notes. Python skips them.
RuleDocstring under def/class.
RememberExplain why, not every line.
