NameError fix calculator.py

[ayush1999]

using the normal input() function was causing a NameError.
changing it to raw_input() fixed this.

@ayush1999 this program is written in Python 3.

@ayush1999 also I do have a NameError Exception in the program and it works.

@ayush1999 python3 input will give you a string no matter what you input.py2 is different so,raw_input =>string,and input may result in a number if you input like"1+2".if wrong,thanks for telling me.

In python 2, raw_input will always return a string, however input will treat it as an expression.
In Python 3, input returns a string. Maybe this helps!

Can someone please tell me how *args and **kwargs work in Python?
I am having difficulty in using them.
Thanks!

@ayush1999
*args is used to send a non-keyworded variable argument list to the function.
**kwargs is used to pass keyworded variable of arguments to a function.

def foo(first, *args, **kwargs):
    print('Required argument: ', first)
    for v in args:
        print('Optional argument (*args): ', v)
    for k, v in kwargs.items():
        print('Optional argument %s (*kwargs): %s' % (k, v))

>>> foo(1, 2, 3, 4, k1=5, k2=6)

Required argument: 1
Optional argument (*args): 2
Optional argument (*args): 3
Optional argument (*args): 4
Optional argument k2 (*kwargs): 6
Optional argument k1 (*kwargs): 5
