粗体代表用户输入

以下是一个示例互动：

Welcome to Mohamed Ismail's Recipe Viewer

Add Recipe (add), Load Recipe (load) or Delete Recipe (delete)

add

Input recipe id = 1

Input recipe name = Cake

Summary

Recipe id = 1

Recipe for Cake

Save Recipe?

Yes

...

Saved Succesfully

Add Recipe (add), Load Recipe (load) or Delete Recipe (delete)

load

Here are your existing recipe id's

Loading...

['1']

Select Recipe by id 1

[('Recipe id =', '1')]

    [<function function.<locals>.fileb at 0x105920400>] # this is the error
Go back? or exit

这是我的代码：

import time

currentrecipes = []
rp1 = []
rp2 = []


print("Welcome to Mohamed Ismail's Recipe Viewer")
time.sleep(1)

def function():
     print('Add Recipe (add), Load Recipe (load) or Delete Recipe (delete)')

            b = input('Input recipe name = ')
            filea = ("Recipe id =",a)
            fileb = ("Recipe for =",b)
            print('')
            print("Summary")
            print("------------------")
            file1 = print("Recipe id =",a)
            file2 = print("Recipe for",b)

            def file():

            userinput = input()
