It has bugs on the exponential part i need help

Two suggestions:

1. Use lowercase. Caps are reserved for class names.
2. Implement the built in `pow()` function.
``````def exponent (x, y):
return pow(x, y)
``````
``````print (exponent(2, 3))      #  8

print (exponent(8, 1/3))    #  2.0

print (exponent(4, 3/2))    #  8.0
``````
