1.def中变量为单独,则返回单值,如为*变量,则返回元组,如为**变量,则变量需为a=XXx之类,返回字典

def add1(**x): return x add1(1,23,232321) Traceback (most recent call last): File ” < pyshell#73>”, line 1, in < module> add1(1,23,232321) TypeError: add1() takes 0 positional arguments but 3 were given add1(a=23,b=22) {‘a’: 23, ‘b’: 22} def add1(*x): return x add1(1,23,4) (1, 23, 4)
