Python variable length parameter *args, **dictargs

1. the variable name with an asterisk (*) will hold all the unnamed variable parameters, cannot store dict, or error.

Such as:

1  defMultiple (ARG, *args):2      Print "ARG:", Arg3     #print variable length parameters4       forValueinchargs:5          Print "Other args:", Value6  7  if __name__=='__main__':8Multiple (1,'a', True)

Output:

2. the variable name with an asterisk (* *) holds all the unnamed variable arguments

1  defMultiple2 (* *args):2     #print variable length parameters3       forKeyinchargs:4          PrintKey +":"+bytes (Args[key])5  6  if __name__=='__main__':7Multiple2 (name='Amy', age=12, Single=true)

Output

3. There are *args and **dictargs:

1 defMultiple (ARG, *args, * *Dictargs):2     Print "ARG:", Arg3     #Print args4      forValueinchargs:5         Print "Other args:", Value6     #prints the indefinite length parameter of the dict type args7      forKeyinchDictargs:8         Print "Dictargs:"+ key +":"+bytes (Dictargs[key])9 Ten if __name__=='__main__': OneMultiple (1,'a', True, Name='Amy', age=12,)

Output:

Python variable length parameter *args, **dictargs
