square root in python

import math

squared = math.sqrt(toSquare)

import math
print(math.sqrt(589485))

import math
a = input("what do you wnat to square root")
print(math.sqrt(a))

def square_root(num):
  	return num**0.5
#prints out 4
print(square_root(16))
#prints out 10
print(square_root(100))

# Python3 program to demonstrate the error in  
# sqrt() method  
  
# import the math module  
import math  
  
# print the error when x<0  
print(math.sqrt(-1))  

x = 9
y = x ** 0.5

import math
answer = math.sqrt(16)

#use ** instead of ² or ^2
