从多个列表中生成随机条目的Python代码

Question

我是Python新手，正在尝试编写一个代码，通过从列表中选择一个随机条目来生成一个故事的核心元素[主题] [特征] [主题] [地点]和[线路]。我写的代码如下。

我有2个问题：

1）目前的代码会允许我创建每个列表中的新条目，但是当我关闭Python和重新启动程序，我创建都不见了条目。我怎样才能使新条目永久存储在列表中？我需要某种数据库吗？

2）6. Storybox的代码 - 我希望程序做的主要事情！ - 不管用。任何关于如何让Python打印每个列表中随机选择的条目的建议？

在此先感谢您的帮助。

#Storybox program 
#Generates a random selection of my story ideas 


characters = [] 
traits = [] 
locations = [] 
themes = [] 
lines = [] 

choice = None 

while choice != "0": 

    print(
    """ 

Storybox: 

0 - Exit 
1 - Add character 
2 - Add trait 
3 - Add location 
4 - Add theme 
5 - Add line 
6 - Generate Story 
7 - View all entries 

""" 
) 

    choice = input("Choice: ") 
    print() 


#exit 
    if choice == "0": 
     print("Goodbye") 

#add a character 
    elif choice == "1": 
     character = input("Enter character: ") 
     characters.append(character) 

#add a trait 
    elif choice == "2": 
     trait = input("Enter character trait: ") 
     traits.append(trait) 

#add a location 
    elif choice == "3": 
     location = input("Enter location: ") 
     locations.append(location) 

#add a theme 
    elif choice == "4": 
     theme = input("Enter theme: ") 
     themes.append(theme) 

#add good lines 
    elif choice == "5": 
     line = input("Enter good line: ") 
     lines.append(line) 


#Generate storybox 
    elif choice == "6": 
     print("Your storybox is....") 
     storyboxcharacter = random.choice(characters) 
     print(storyboxcharacter) 
     storyboxtrait = random.choice(traits) 
     print(storyboxtrait) 
     storyboxtheme = random.choice(themes) 
     print(storyboxtheme) 
     storyboxlocation = random.choice(locations) 
     print(storyboxlocation) 
     storyboxline = random.choice(lines) 
     print(storyboxline) 


#Display all entries so far 
    elif choice == "7": 
     print("Characters:") 
     for character in characters: 
      print(character) 

     print("Traits:") 
     for trait in traits: 
      print(trait) 

     print("Themes:") 
     for theme in themes: 
      print(theme) 

     print("Locations:") 
     for location in locations: 
      print(location) 

     print("Good lines:") 
     for line in lines: 
      print(line) 

input("\n\nPress the enter key to exit.") 

Answer 1

1）是的，您需要以某种方式将数据存储在文本文件或数据库中。数据库在这一点上是过分的，所以我建议像json这样的东西。

2）删除randint解决 - random.choice是肯定更好
