如何将** kwargs发送到具有已定义参数的函数？

Question

I'm looking for a way to send **kwargs to a function with defined parameters , without having to modify it.

For example , I want to pass the parameters as **kwargs when calling the following init method:

class ExampleClass(object):
def __init__(self, attr1=None, attr2=None, attr3=None):
    super(ExampleClass, self).__init__()
    self.attr1=attr1
    self.attr2=attr2
    self.attr3=attr3

Can anyone think of a way doing so?

Answer 1

ExampleClass(**{"attr1":1, "attr2":2, "attr3":3})
