Comments

Before moving further, quick thing to learn: comments. Comment is a part of code which is not executed (ignored by the program). Comments are used as notes that developers leave for themselves or other users.

In Python there are single-line comments and multi-line comments (used less often).

Single-line comment start with symbol #. If placed at the beggining of the line entire line is ignored.

12
# this is a comment that I left as a note for myself print("Hello, World!")
copy

Comments can be placed at any position of any line. Anything before # sign will be executed, anything after # sign will be ignored.

1
print("Hello, world!") # Comments can be very helpful
copy

You can switch certain lines of code off by just placing a # sign (turning it into a comment).

12
# print("Hello, Mary!") print("Hello, Jane!")
