You should parse the file content with ast.literal_eval to turn it into an actual list first, and then use the str.join method to join the list items into one string:

from ast import literal_eval

with open("Result.txt","r+",encoding="utf8") as file, open('output.txt', 'w') as output:
    output.write(' '.join(literal_eval(file.read())))

  • but it doesn't change the contents of the file.. how to update the file or write it to a new text file? @blhsing – Tab Key Oct 17 '18 at 10:27
  • I've updated my answer with how you can write the output to a new text file `output.txt`. – blhsing Oct 17 '18 at 10:34

You are given a string.

trim the brackets with 

text = text[1:-1]

Then remove the "'" and ","

text.replace("'", "").replace(",","")

You can also remove the '\\n' the same way.
