Python Powxy

pow(x, y, z) is a built-in function in Python 3 to calculate x to the power y, and if z is present, returns x to the power y modulo z.

Arguments

The arguments must have numeric types. This function takes two arguments, x and y, as well as three, x, y, andz. If z is present, x and y must be of integer types, and y must be non-negative.

Return

If z is present, it returns x to the power y modulo z. If only x and y are present, it returns x to the power y (same as x**y).

Example

print(pow(2,4))    # prints 16
print(pow(10,-2))  # prints 0.01
print(pow(4,3,5))  # prints 4
