간단한 파이썬 등록 수정 삭제

이상하게 input이 안먹히는 에러가 있어서 그냥 숫자 때려박는 등록수정삭제 코드

import sys
 
list = ['apple','dream']
 
print(sys.version)
print("restorants")
print('=============')
print('1. insert')
print('2. delete')
print('3. change')
say = 3
print('insert data')
data = 'apple'
if say == 1:
    list.append(data)
elif say == 2:
    for i in list:
        if data == i:
            idx = list.index(data)
            del list[idx]
elif say == 3:
    changedata = "RNX"
    for i in list:
        if data == i:
            idx = list.index(data)
            list[idx] = changedata
 
print(list)
 

def로 나눈거

import sys
 
list = ['apple','dream']
 
def insertR(data):
    list.append(data)
def deleteR(data,list):
    for i in list:
        if data == i:
            idx = list.index(data)
            del list[idx]
def changeR(data,list):
    changedata = "RNX"
    for i in list:
        if data == i:
            idx = list.index(data)
            list[idx] = changedata
 
print(sys.version)
print("restorants")
print('=============')
print('1. insert')
print('2. delete')
print('3. change')
say = 2
print('insert data')
data = 'apple'
if say == 1:
    insertR(data)
