虚心请教，实参传的字典为啥没走到形参的不定长关键字参数里的print，而且还报错了
def dump(index, default=0, *args, **kw):
print('打印函数参数')
print('index:', index)
print('default:', default)
for i, arg in enumerate(args):
print(f'arg[{i}]:', arg)
for key,value in kw:
print(f'keyword_argument {key}:{value}')
print('')
dump(0)
dump(0,2)
dump(0,2,"Hello","World")
dump(0,2,"Hello","World", install='Python', run='Python Program')
打印函数参数
index: 0
default: 2
arg[0]: Hello
arg[1]: World
