dict instead of switch block

switchdict.py

def a():
    print("a")


def b():
    print("b")


def default():
    print("default")


c = lambda: print('This is "c" case.')


def printdic(x):
    {1: a, 2: b, 'c': c}.get(x, default)()


if __name__ == '__main__':
    import sys
    printdic(sys.argv[1] if len(sys.argv) > 1 else "c")

Hack on hack: not very conventional use of dict + kind of nasty one-line guard for getting argument from command line (it fails in some cases).
