How to get the type of an object which data has passed by user

Question

I taking input from user in python, How to know user has passed int or string or float etc??

number1 = eval(sys.argv[1])
number2 = eval(sys.argv[2])

if user passed input is float or int, i want to sum them, but how to know which type of data user passed? because all data which user passes is default type is string.

Answer 1

We can use eval() for that,

import sys


def main():
    number1 = eval(sys.argv[1])
    number2 = eval(sys.argv[2])
    print(number1 + number2)


if __name__ == '__main__':
    main()

when the user enters an integer as an input the input() function returns a string, but in the case of eval() it will evaluate the returned value from a string to an integer, same in float . No need to check data type every time.
