Error: must be real number, not str

Question

Hi,
why in the following block I get this error: "must be real number, not str"
import math
def sqrt_root(x):
return math.sqrt(x)
x = input("Enter your number:")
print("The SQR ROOT of ", x, " is:", sqrt_root(x))

Answer 1

When you call the function, call it like this:
sqrt_root(int(x))
You are passing in a string, gotten from input, into a function that requires a integer. You need to convert it using the int() function.

Answer 2

Ariela your suggestion worked. Thanks for your clear answer
