type_constraint 0.0.3

a type constraint tool for python function

Example:

from type_constraint import BasicCheck, CheckMeta, Check

class A: ….__metaclass__ = CheckMeta() ….def f(self, i, j): ……..””” ……..@param i str ……..@param j str ……..””” ……..return i + j

a = A() a.f(‘1’, ‘2’) “”” result is: 12 “””

@BasicCheck def test_func(i, j): ….””” ….this is a test function for type constraint …. ….@param i int :this is the first operand ….@param j float :this is the second operand …. ….@return float ….””” ….return i / j

test_func(3, 1.1) “”” result is: 2.72727272727 “””

test_func(3, 4) “”” result is: TypeError: argument:j should be <type ‘float’>, not <type ‘int’>. “””
