is it possible to pass argument to a function in this way?

Question

I am trying to pass argument to a function in this fashion

GroupGeneralConfig(selectedGroup = "Group1")

and the function looks like this...

def GroupGeneralConfig(self, *args)
     img = str(args[0]) + "abc"

whenever i execute this program it is throwing like this...

TypeError: GroupGeneralConfig() got an unexpected keyword argument 'selectedGroup'

whats wrong here

Answer 1

You'll want the double star :

def GroupGeneralConfig(self, **kwargs):
    img = str(kwargs[selectedStreamGroup]) + "abc"

Answer 2

如果要使用kwargs ，则应先定义它：

def GroupGeneralConfig(self, **kwargs):

Answer 3

What you are passing in is a keyword argument, change your method to accept keyword arguments first. Like this

def GroupGeneralConfig(self, *args, **kwargs)
     img = str(args[0]) + "abc"

Then you can pass the arguments first and then the keyword arguments, like:

GroupGeneralConfig(arg_x, arg_y, kwarg_x=1, kwarg_y=2)
