Replacing newline doesn't work

Question

I have a .txt file form which I read multiple lines and append an array with every line. Unfortunately I also have the line breaks in the array.

When I try to replace them with line.replace("\n", ""), nothing will happen.

It's not about spaces, but about the \n part. .strip didn't work either. — derfium, Jan 31 '17 at 21:37
My thought is, that python does \n not see as a part of the string, but as a command. Maybe its something like that? — derfium, Jan 31 '17 at 21:38
After you read the files and uploaded the array, can you go through the array and delete every "\n"? You could use that replace method which have suggested by others — Kroy, Jan 31 '17 at 21:41

Are you just doing line.replace("\n", "")? If so, that's the problem. You are doing the replacement, then throwing away the result. You need:

line = line.replace("\n", "")

I had the same problem, but even saving the result in another variable. I started breaking it in code units to find the problem and I found that my input had carriage returns, which is '\r'. They made visually the same result as the '\n' in the output file. So I fixed it by doing the following:

result = input.replace("\n", "").replace("\r", "");
