如何使inpit影响函数的参数？ python，在我试图制作靴子的时候对我不适

Question

def market_list(user_request):
    fixed_list_option_1 = customer_products_string.split(' ', )
    if user_request == 1:
        return fixed_list_option_1
    elif user_request == 2:
        return fixed_list_option_1.count


customer_products_string = "pizza,apple"
user_request = input("What is your request? (insert the number of the command) : ")
print(market_list(user_request))

Answer 1

输入似乎在这里字符串。这就是为什么您应该使用user_request ==“ 1”或“ 2”或int（输入（“ ...”））的原因。

def market_list(user_request):
    fixed_list_option_1 = customer_products_string.split(',', )
    if user_request == "1":
        return fixed_list_option_1
    elif user_request == "2":
        return len(fixed_list_option_1)

customer_products_string = "pizza,apple"
user_request = input("What is your request? (insert the number of the command) : ")
print(market_list(user_request))
