Variables
A variable stores a piece of data, and gives it a specific name.
For example:
spam = 5
Booleans
A boolean can only have two values, true or false.
a = True
b = False
Remember to capitalize!
Reassigning
To change the value of a variable.
my_int = 7 my_int = 3
Whitespace
Whitespace is used to structure code.
We should use two-space or four-space indentations.
Single Line Comments
We use the # sign for comments. A comment is a line of text that Python won't try to run as code. They make our program easier to understand.
# I love python!
Multi-Line Comments
The # sign will only comment out a single line. For multi-line comments, we can include the whole block in a set of triple quotation marks.
""" Python is an interesting language to study! """
Math
We can add, subtract, multiply, divide numbers like this:
addition = 72 + 23
subtraction = 108 - 204
multiplication = 108 * 0.5
division = 108 / 9
Exponentiation
We use ** to work with exponents.
eight = 2 ** 3
Modulo
Modulo returns the remainder from a division.
one = 3 % 2
Remember that we can't divide by 0 or we will get an error. Same goes for %.
