我真的就不明白了，两个一模一样的程序，符号都一模一样咋就运行

for循环的第一个变量有误，源代码发来，我给你改

I made your salad sandwich.
I made your apple sandwich.
I made your banana sandwich.
I made your orange sandwich.
['salad', 'apple', 'banana', 'orange']

sandwich_orders= ['salad', 'apple', 'banana', 'orange']
finished_sandwiches = []
for sandwich_order in sandwich_orders:
print("I made your " + sandwich_order + " sandwich.")
finished_sandwiches.append(sandwich_order)
print(finished_sandwiches)
