本文介绍了一个使用Python编写的简单互动程序的设计与实现过程。通过结合input和argv的应用，引导用户进行对话并收集反馈。此外，文章还展示了如何通过更改prompt变量来调整程序交互方式，并增加了额外参数以增强程序的功能。

题目

通过 input 和 argv 配合实现一个简单的互动程序。

加分练习

了解 Zork 和 Adventure 是怎样的游戏。
将 prompt 变量改成完全不同的内容运行一遍。
给你的脚本添加一个参数，让你的程序用到这个参数。
确认你弄懂了三引号 """ 可以定义多行字符串，而 % 是字符串格式化工具。

我的答案

基础练习答案

from sys import argv

script, user_name = argv
prompt = '> '

print("Hi %s, I'm the %s script." % (user_name, script))
print("I'd like to ask you a few questions.")
print("Do you like me %s?" % user_name)
likes = input(prompt)

print("Where do you live %s?" % user_name)
lives = input(prompt)

print("What kind of computer do you have?")
computer = input(prompt)

print("""
Alright, so you said %r about liking me.
you live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" % (likes, lives, computer))

14.2 其他 prompt

from sys import argv

script, user_name = argv
prompt = '%s > ' % user_name    # 改成这样试试

print("Hi %s, I'm the %s script." % (user_name, script))
print("I'd like to ask you a few questions.")
print("Do you like me %s?" % user_name)
likes = input(prompt)

print("Where do you live %s?" % user_name)
lives = input(prompt)

print("What kind of computer do you have?")
computer = input(prompt)

print("""
Alright, so you said %r about liking me.
you live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" % (likes, lives, computer))

14.3 加一个参数

from sys import argv

script, user_name, call = argv    # 加一个 call
prompt = '%s > ' % user_name    # 改成这样试试

print("Hi %s, I'm the %s script." % (user_name, script))
print("Hmmm， you want me call you %s" % call)    # call 在这里
print("I'd like to ask you a few questions.")
print("Do you like me %s?" % user_name)
likes = input(call + " " + prompt)

print("Where do you live %s?" % user_name)
lives = input(call + " " + prompt)

print("What kind of computer do you have?")
computer = input(call + " " + prompt)

print("""
Alright, so you said %r about liking me.
you live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" % (likes, lives, computer))
