# FAQ : Why the hell you need var_dump in Python?
if __name__ == '__main__':

    # Let's say I have a dictionary which one of its value contains an instance of a class
    class Human:
        def __init__(self):
            self.name = 'Clark'
            self.age = 15

        def fly(self):
            print('up up and away')
    data = {'name' : 'clark', 'object' : Human()}

    # use print
    print(data)
    # print will give you this:
    # {'object': <__main__.Human instance at 0xb724f3ec>, 'name': 'clark'}

    # use pprint
    import pprint
    pprint.pprint(data)
    # pprint will give you this:
    # {'name': 'clark', 'object': <__main__.Human instance at 0xb724f3ec>}

    # use var_dump
    var_dump(data, show=True)
    # var_dump will give you this:

    #     'object' : <Instance of __main__.Human> (
