Variables and data types

In Python, a variable is created the moment you first assign a value to it. You do not need to declare its type.

Type	Description	Example
int	Integer numbers	42, -10
float	Decimal numbers	3.14, -0.5
str	Text strings	"Hello"
bool	Booleans (True, False)	True
None	Absence of value	None

Type conversion

You can convert types with functions like:

int("5")       # 5
str(42)        # "42"
float("3.14")  # 3.14
