*args, **kwargs in python

[Humble]

why are these used for ? its used for passing variable number of arguments , by variable I mean “you are or the function definition does not know how many arguments are going to get passed” .. *args is used to send a non-keyworded variable length argument list to the function.

>>> def var_args(*Args):
...     for arg in Args:
...             print arg
... 
>>> var_args(1,34,"hum","asd")
1
34
hum
asd
>>> 


oh , Did I make a mistake by mentioning *Args in function defnintion instead of *args.. No, I didnt.. That said, the keyword is not important . What is important is that *.

**kwargs helps you to pass keyworded variable length of arguments to a function. You should use **kwargs if you want to handle named arguments in a function.

>>> def var_args1(**wargs):
...     for k,v in wargs.items():
...             print k,v
... 
>>> var_args1(name="2",hobby="cricket")
hobby cricket
name 2
>>> 



So wargs ( again I used a different name than kwargs ) got it as dictionary.. 

>>> k={"name1":"humble", "dist":"asdom"}
>>> var_args1(**k)
dist asdom
name1 humble
>>>
