how to do a square root in python

1from math import * # We import the math module
2print(sqrt(16)) # We print the square root of the number 16

1import math
2a = input("what do you wnat to square root")
3print(math.sqrt(a))

1a = int(input("enter a real number: "))
2sqrt = a**(1/2)
3print("the square root of ",a ,"is",sqrt)

1import math
2answer = math.sqrt(16)

1def square_root(num):
2  	return num**0.5
3#prints out 4
4print(square_root(16))
5#prints out 10
6print(square_root(100))
