How do you write the Pythagoras equation in python? Is it written as shown below or not. If not please describe why this is incorrect and how I can correct it.
math.sqrt(XLength^2+YLength^2)
In pygame you can use pygame.math.Vector2.length:
l = pygame.math.Vector2(XLength, YLength).length()
In general you can use math.hypot:
l = math.hypot(XLength, YLength)
^ however is the Bitwise Exclusive Or operator (see opertor). The Exponentiation operator is **:
l = math.sqrt(XLength**2 + YLength**2)
