how to give value by using module in python3

Question

let's suppose that there's a two python file

file1

from math import factorial 
def factorial(n): 
 return factorial(n)

file2

from file1 import factorial 
a = input("n : ") 
print (factorial(a))

Question:

I want to give the value of 'a' from file2 to file1, but I don't know how to do it ?

• caped114: Instead of importing factorial from file1 to file2, import 'a' from file2 to file1. You can directly take input in file1. What is the reason to take input in a separate file and then import it? you can take input directly in file1.

Answer 1

file1

 import math
 def fact(n): 
 return math.factorial(n)

file2

from file1 import fact 
a = int(input("n : "))
print (fact(a))

First of all import math module in file to calculate the factorial defined in math module and then import fact function from file1 to file2

now take some input by input() the number but you have to convert it to integer.
