Doubt in the function argument in python

Question

What is the difference between a and *a in the argument variable?
I have seen this many a times but couldn't understand it.
Can anyone explain in detail?

Answer 1

I made good example
def log(*a):
print(*a, file=sys.stderr)
log(2,"banana")
log(2,4,10,20)

Operator * allows to call method with as many parameters as you want without wrapping them into array or tuple like this log((2,4,10,20))
Python does it for you

Answer 2

def myfunct(*args):
for x in args:
print(x)
one = 1
two = 2
three = 3
four = 4
myfunct(one, two, three, four)

five = 5
myfunct(one, two, three, four, five)

it scoops up all the function arguments into a tuple so you can then iterate over it..

Answer 3

Thank you

Answer 4

Try to run my example without one of * for better understanding

Answer 5

Ok
