what is ,*, ?

[Sagar]

I have written a code to understand the use of bare "*" in function argument list and I am sharing that with everyone.

I have created a function called myFunction having three arguments "a","b" and "c". I placed "*" between a and b

def myFunction(a,*,b,c):
	print('a',a)
	print('b',b)
	print('c',c)

myFunction(10,c=20,b=12)

Output:

Output:
a 10
b 12
c 20

The "*" in argument list of a function ensures that the arguments after that are Non-positional
Non-positional argument means that the order of that argument during function call is not fixed and value is passed using key of that argument.
The arguments before * are positional arguments and values are passed to these argument without keys.

Another code:

def myFunction(*,a,b,c):
	print('a',a)
	print('b',b)
	print('c',c)

myFunction(a=10,c=20,b=12)
