Usage

Everything lives under validations:

from pyis import validations

Type checks — validations.type

Uses exact type(x) is ... (not isinstance), except is_function which uses callable.

Method	True when
is_int(x)	type(x) is int
is_string(x)	type(x) is str
is_float(x)	type(x) is float
is_list(x)	type(x) is list
is_bool(x)	type(x) is bool
is_dict(x)	type(x) is dict
is_tuple(x)	type(x) is tuple
is_function(x)	callable(x)

validations.type.is_int(1)          # True
validations.type.is_string("a")     # True
validations.type.is_list([1, 2])    # True
validations.type.is_function(print) # True

Presence — validations.amount

Method	True when
is_set(x)	x is not None
is_empty(x)	x is None

validations.amount.is_set(0)     # True
validations.amount.is_empty(None)  # True

Numbers — validations.numbers

Method	True when
is_positive(x)	x > 0
is_negative(x)	x < 0
is_zero(x)	x == 0

validations.numbers.is_positive(2.5)  # True
validations.numbers.is_zero(0)        # True
