I need help on regards to the following code challange.

The first one requires that I figure out how to square it. I can't either because math is not defined or that you can't use (number ^ 2), and I do not know why.

import math

number = input("number plz..  ")

def square(number):
    return math.sqrt(int(number))

new_number = square(number)
print(new_number)

An easy way to square a number is to multiply it by itself. For example:

square_of_num = num * num

I prefer exponentiation syntax (**) to square numbers:

squared_number = number**2

Good point, the ^ symbol is not used in Python for exponentiation but ** is.

Thank you all, this has been holding me back a few days!

And all I had to change was 2 Characters?!?

I find the most common errors (at least my own) are caused by a single character. :stuck_out_tongue_winking_eye:
