Python Basics

Naming Conventions - Python Indentifiers

When you are giving a name to a variable, function, class or basically anything that you're designating in Python (like lives, score, etc), make sure you follow these rules:

1. it starts with a letter A to Z or a to z or underscore _
2. it does not contain punctuation characters like @, $, &, or any other symbol
3. it is case sensitive (Score is not the same variable as score. Dog is not same as dog )
4. it does not contain any words in the reserved word list:

from

raise

def

Comments

Comments are used to talk to people reading your code.

You will use it for things like:

• writing your name
• making notes
• labeling sections of code
• blocking out code for later (instead of deleting it)

To make a comment, start the code with a hashtag #
