파이썬에서 함수를 int로 변환하는 방법은 무엇입니까? 아니면 가능한가?

Question

문제점 : 함수 위치를 입력/정수로 find_second 함수로 변환/사용하는 방법을 모르겠다.

코드

# Define a procedure, find_second, that takes 
    # two strings as its inputs: a search string 
    # and a target string. It should return a 
    # number that is the position of the second 
    # occurrence of the target string in the 
    # search string. 

def position (search_string, target): 
    position_target = search_string.find(target) 
    return int(position_target) 

def find_second (search_string, second_target): 
    return search_string.find(second_target, position+1) 

danton = "De l'audace, encore de l'audace, toujours de l'audace" 

print find_second(danton, 'audace')`

위치는 기능입니다. 대안은 다음과 같습니다.

def find_second(search_string, target): 
    temp = search_string.find(target) 
    return search_string.find(target, temp) 

danton = "De l'audace, encore de l'audace, toujours de l'audace" 

print find_second(danton, 'audace')`
