Python: Проверка типа переменной

python_type_check.py

# Use the type() builtin function:

i = 123
type(i)
# <type 'int'>

type(i) is int
# True

i = 123.456
type(i)
# <type 'float'>

type(i) is float
# True


# To check if a variable is of a given type, use isinstance:

i = 123
isinstance(i, int)
# True

isinstance(i, (float, str, set, dict))
# False
