Examples

from argreq import argument, requirement

@argument('a', '>10', type=int)
def int_grater_than_10(a):
    '''If a is smaller than 10, function raises 'NotValidArgumentError' '''
    print(f'a ({a}) is int and larger then 10!')

@argument('a', ('>10', '<20'), type=int)
def other_func(a):
    '''Check if a is grater than 10 AND smaller than 20'''
    print(f'a {a} is int and between 10 and 20')

@argument('a', '10<{}<20', type=int)
def prettier_other_func(a):
    '''Same as above but in a single requirement'''
    print(f'a ({a}) is int and between 10 and 20 and prettier ;)')

@argument('a','>0')
@argument('b','>0')
def div(a,b):
    '''Check if both a and b positive'''
    print(f'{a}/{b}={a/b}')

@argument('d', '"a" in {}', type=dict)
def dict_func(d):
    '''Check if d has the key 'a' '''
    print(f'd ({d}) has "a" in it')

@requirement('{a}>{b}>0')
def a_grater_than_b_and_positives(a, b):
    '''Check if a is grater then b and both positives'''
    print(f'{a} > {b}')
