How to use a function within a function in python

I want to use the function f in the function radiationExposure, but this code return nothing.

def f(x):
    import math
    return 10*math.e**(math.log(0.5)/5.27*x)


def radiationExposure(start, stop, step):    
    if start < 0 or stop < start or step < 0:
        print("Invalid inputs!")
    else:
        result = 0 # Total radiation exposure area
        for i in range(start, stop + 1):
            result += f(i)*step
        return result


radiationExposure(5, 10, 1)

When you run a Python script, it will not auto-echo the result. Your code runs fine, but you need to explicitly print the result:

print(radiationExposure(5, 10, 1))

Your script, when run, will now print 22.9424104106.
