PySwitchCase

A pure python way to efficiently do a c++ style switch case in Python 3.7+. Should work in 3.6 as well.

Any improvements and/or optimizations are welcome.

------------- Usage -------------

See this for more examples.

example 1

test = 10
with SwitchCase(test) as sc:
    sc(2, on_true=print, on_true_args=('test 1',) )
    print('sub 1')
    sc(10, on_true=print, on_true_args=('test 2',) )  # will break here due to match found.
    print('sub 2')
    sc(12, on_true=print, on_true_args=('test 3',) )

example 2

test = '10'
with SwitchCase(test, catch_value_to_check=True) as sc:
    on_true = lambda x: print(f'testing... {x}')

    sc(2, on_true=on_true)
    print('sub 1')
    sc('1', on_true=on_true)
    print('sub 2')
    sc('10', on_true=on_true)  # will break here due to match found.

example 3

def run_test(*args, **kwargs):
    return {
            'args': args,
            'kwargs': kwargs
            }
test = '10'
switcher = SwitchCase(test, catch_value_to_check=True)
with switcher as sc:
    on_true = lambda x: run_test(x, test=True)

    sc(2, on_true=on_true)
    print('sub 1')
    sc('1', on_true=on_true)  # will break here.
    print('sub 2')
    sc('10', on_true=on_true)
print(switcher.result)
