[PYTHON] When using if and when using while

b = time.clock()
execute() #processing
a = time.clock() - b

import time

def hoge_while(h):
    while h % 15 == 0: return "KinokoTakenoko"
    while h % 3 == 0: return "Kinoko"
    while h % 5 == 0: return "Takenoko"
    return ""

def hoge_if(h):
    result = ""
    if h % 3 == 0: result += "Kinoko"
    if h % 5 == 0: result += "Takenoko"
    return result

def loop(hoge_list):
    i = 1
    while i <= 10000000:
        i, hoge_list[i-1]
        i += 1

before = time.clock()
loop([hoge_if(i) for i in range(1, 10000001)])
print time.clock() -before
before = time.clock()
loop([hoge_while(i) for i in range(1, 10000001)])
print time.clock() -before
