How to make general functions for ecuations

[Mondata]

Thanks, deanhysad.

Here a further improvement with your suggestion and other bits:

def pythagoras(h=None, x=None, y=None):
    '''Pythagorean Theorem:
    The area of the square whose side is the hypotenuse is equal
    to the sum of the areas of the squares on the other two sides.'''
    
    try:
        if h is None: return sqrt(x ** 2 + y ** 2)
        elif x is None: return sqrt(h ** 2 - y ** 2)
        elif y is None: return sqrt(h ** 2 - x ** 2)
        else: return "No unknown values to calculate." 
    except:
        return "Insufficient data."    

print(pitagoras(x=3, y=4))    # 5.0
print(pitagoras(h=5, x=3))    # 4.0
print(pitagoras(h=5, x=4))    # 3.0
print(pitagoras(h=5, x=4, y=4))    # No unknown values to calculate.
print(pitagoras(h=5))    # Insufficient data.
print(pitagoras(x=4))    # Insufficient data.
print(pitagoras(y=4))    # Insufficient data.
