manipulating text file in python

text with broken line and dash:

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

code:

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())

Correct output:

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

Exit from my code:

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

The text was written in the text editor.

I need this help.

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

only happens when I read the file written in a text editor, I need to create a list with these words to make a comparison.

This will do (updated)?

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())

This line 

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

removes the '\n' from your lines because it splits on them. Characters you split on are never part of the results.

So this line

line = line.replace('-\n','')

can not find anything to replace.

Use line = line.rstrip("-") instead, it will remove the '-' from the right end of your string if present.

You might benefit from reading/following How to debug small programs (#1) - to get some tips on how to debug your own program.

Edit:

  • You get a ' ' from your ' '-join()ing of split lines - you need to keep track on which lines ends on - and merge it with the following one. Its easier to simply do 2 replaces like this: 
def file_string():
    with open('speech.txt','r') as file:
        lines = file.read()

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

print(file_string())

to come to your wanted result. Uncomment the commented lines and remove the lines = """...""".
