如何在Python 3中获取多行代码的用户输入？ [英] How to get user input for multiline lines in Python 3?

问题描述

总结newb在这个，并试图弄清楚这一点。我知道常规输入函数可以接受
单行，但只要您尝试编写一个字符串段并敲下一行的输入，它就会终止。是否有初学者友好的方式接受多行用户字符串输入作为变量？谢谢！

解决方案

在程序中执行此操作的常用方法是使用我完成字符串期间），并继续阅读，直到读取的行匹配该字符串。

  print（输入尽可能多的文本行）
 print（完成后，单独输入一个单独的句点。）
 
 buffer = [] 
 True： 
 print（>，end =）
 line = input（）
 if line ==。：
 break 
 buffer.append（ ）
 print（）
 print（multiline_string）
 multiline_string =\\\
.join（buffer）
 
 print（You entered ... ）
  

Total newb at this and tried to figure this out. I know that the regular input function can accept single lines, but as soon as you try to write a string paragraph and hit enter for the next line, it terminates. Is there a beginner friendly way to accept multiline user string inputs as variables? Thanks!

解决方案

A common way of doing this in programs is to have an "I'm done" string (e.g. a single period), and to keep reading in lines until the line read matches that string.

print("Enter as many lines of text as you want.")
print("When you're done, enter a single period on a line by itself.")

buffer = []
while True:
    print("> ", end="")
    line = input()
    if line == ".":
        break
    buffer.append(line)
multiline_string = "\n".join(buffer)

print("You entered...")
print()
print(multiline_string)
