hypotenuse.py

# Use incremental development to write a function called hypotenuse
# The function returns the length of the hypotenuse of a right triangle
# The function gets the other two legs as arguments
# Record each stage of the development

# SOLUTION

# v1.0 --------------------------
def hypotenuse(a, b):
    return 0

print (hypotenuse(3,4))  # 0


# v2.0 -------------------------
def hypotenuse(a, b): 
    sum = a**2 + b**2
    return sum

print(hypotenuse(3, 4))  # 25


# v3.0 -------------------------
import math
def hypotenuse(a, b): 
    sum = a**2 + b**2
    return math.sqrt(sum)
    
print(hypotenuse(3, 4))  # 5.0
