Types and Variables

This lesson introduces Python's type system. Replace this with your own content.

Declaring variables

A variable gets its type from the value assigned to it. A type hint after the name documents the type you expect:

1
count = 0      # int
2
price = 9.99   # float
3
name = "Ada"   # str
4
5
age: int = 30
6
ratio: float = 0.5
7
ready: bool = False
8
9
print(type(count), type(price), type(name))
