在python中操作文本文件

Question

带虚线和短划线的文本：

to validate my solution was
I need to take the bench test
of the elaborated algorithm
only after the table test that
the program was implemen-
ted this strategy spared
development time

代码：

def file_string():
    with open('speech.txt','r') as file:
        lines = file.read().split("\n")
     string = []
     for line in lines:
         line = line.replace('-\n','')
         string.append(line)
     return (' '.join(string))

print(file_string())

正确输出：

to validate my solution was I need to take the bench test of the elaborated algorithm only after the table test that the program was implemented this strategy spared development time

退出我的代码：

to validate my solution was I need to take the bench test of the elaborated algorithm only after the table test that the program was implemen- ted this strategy spared development time

文本是在文本编辑器中编写的。在

我需要这个帮助。在

applying the code sujerido the exit remained:

to validate my solution was I need to take the bench test of the elaborated algorithm only after the table test that the program was implemen ted this strategy spared development time

只有当我读到用文本编辑器编写的文件时，我需要用这些单词创建一个列表来进行比较。在

Answer 1

这条线

lines = file.read().split("\n")

将'\n'从行中删除，因为它拆分了行。你分割的角色永远不会成为结果的一部分。在

所以这条线

^{pr2}$

找不到任何可以替代的东西。在

使用line = line.rstrip("-")代替，它将从right end of your string中删除{}（如果存在）。在

阅读/跟随How to debug small programs (#1)-可以获得一些关于如何调试自己的程序的提示。在

编辑：

• 从分割线的' '-join()得到一个“”-您需要跟踪哪些行以-结束，并将其与下面的一行合并。简单地做两次替换就更容易了：

---

def file_string():
    with open('speech.txt','r') as file:
        lines = file.read()

    return lines.replace('-\n','').replace('\n', ' ') 

print(file_string())

为了得到你想要的结果。取消注释注释行并删除lines = """..."""。在

Answer 2

这可以（更新）吗？在

import re

def file_string():
    with open('speech.txt','r') as file:
        lines = file.read()
    lstr = re.sub(r'\-[\n]*',r'',lines)
    lstr = re.sub(r'[\n]+',r' ',lstr)
    return lstr

print(file_string())
