有人可以用提供的代码向我解释字符串文字吗？

Question

我需要更改什么才能使该程序运行？我得到：

line 10
SyntaxError: Non-UTF-8 code starting with '\x92' in file C:/Users/RobotAdmin/PycharmProjects/untitled3/dialouge on line 10, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

我不知道这是什么意思。

def main ():
    phrases = "Thank You Please Hello Hi How Old Are You What Is Your Address"**       # String literal

    print(phrases[17:22])   # This statement prints a specific segment of characters from the string literal
    name = input('What is your name? :')     # This statement prompts the user to enter their name and accepts it
    print(phrases[23:25] + " " + name)     # Retrieves from the string literal,and combines it with the name
    print(phrases[25:41])   # This Statement asks for the user’s age
    age = input('Age in Years? :')  # This statement prompts the user to enter their age and accepts the age the entered
    print(phrases[42:64])   # This segment asks What the user’s address is
    address = input("Street Address, City, State, Country") #This statement asks user to enter their address
    print (""
           "______________________________"
           "|                            |"
           "|",name,"                    |"
           "|                            |"
           "|",age,"                     |"
           "|                            |"
           "|",address,"                 |"
           "|                            |"
           "|                            |"
           "|____________________________|")

Answer 1

首先，如果你在一个列表中分解你的短语而不是拼接一个字符串，那么可读性会更好。

phrases = ['Hello', 'Thank You', 'How old are you'] #rest of phrases    
print (phrases[0]) #prints out "Hello"

其次，我完全按照您发布的方式测试了代码，而是插入了姓名、年龄和地址的虚拟值，并且代码运行没有错误（尽管可能不是您可能需要的格式）。它所谈论的 Unicode 字符 ('\x92' ) 是一个逗号。你有任何 ext运行eous 逗号吗？

Answer 2

出现错误的原因是 user’s 评论中使用的字符 ’ 与标准 ASCII 的 user's 有细微差别。所以最简单的解决方案就是只更改这两个字符。

如果您希望保留它们，只需在脚本顶部添加合适的编码即可：

# -*- coding: utf-8 -*-

要修复脚本输出，一种解决方案是使用字典来存储您的变量。这有两个好处，首先，您可以轻松确定输入的所有文本的长度。其次，它可以与 format 语句一起使用以替换输出中的占位符。

通过一些额外的（相当奇怪的）符号，我们可以获得 Python 自动添加足够的 space 或下划线填充到所有行。

def main ():
    phrases = "Thank You Please Hello Hi How Old Are You What Is Your Address"        #**       # String literal

    details = dict()
    print(phrases[17:22])   # This statement prints a specific segment of characters from the string literal
    details['name'] = input('What is your name? :')     # This statement prompts the user to enter their name and accepts it
    print(phrases[23:25] + " " + details['name'])     # Retrieves from the string literal,and combines it with the name
    print(phrases[25:41])   # This Statement asks for the user's age
    details['age']  = input('Age in Years? :')  # This statement prompts the user to enter their age and accepts the age the entered
    print(phrases[42:64])   # This segment asks What the user's address is
    details['address'] = input("Street Address, City, State, Country") #This statement asks user to enter their address

    # Determine the length of the longest entry
    max_width = max([len(v) for v in details.values()])

    print ("""
__{0:_<{width}}__
| {0: <{width}} |
| {name:{width}} |
| {0: <{width}} |
| {age:{width}} |
| {0: <{width}} |
| {address:{width}} |
| {0: <{width}} |
| {0: <{width}} |
|_{0:_<{width}}_|""".format('', width=max_width, **details))

main()

这将显示类似于以下输出的内容：

按原样使用下面的内容并将其插入代码之上。

# coding: utf8

注意：必须在顶部。
