Two values from one input in python?

by

The Python way to map

printf("Enter two numbers here: ");
scanf("%d %d", &var1, &var2)

would be 

var1, var2 = raw_input("Enter two numbers here: ").split()

Note that we don’t have to explicitly specify split(' ') because split() uses any whitespace characters as delimiter as default. That means if we simply called split() then the user could have separated the numbers using tabs, if he really wanted, and also spaces.,

Python has dynamic typing so there is no need to specify %d. However, if you ran the above then var1 and var2 would be both Strings. You can convert them to int using another line

var1, var2 = [int(var1), int(var2)]

Or you could use list comprehension

var1, var2 = [int(x) for x in [var1, var2]]

To sum it up, you could have done the whole thing with this one-liner:

# Python 3
var1, var2 = [int(x) for x in input("Enter two numbers here: ").split()]

# Python 2
var1, var2 = [int(x) for x in raw_input("Enter two numbers here: ").split()]
