How to solve file.write() new line unexpected output in python?

Question

I'm trying to write some lines in a file.

My problem arises in the output.

The code looks like this:

fileInput = open("file.txt","r+")
fileOutput = open("fileOut.txt","w")
for line in fileInput.readlines():
   outputString = functionname+"="+otherfunctionname+str(lineNumber)
   fileOutput.write(outputString)
   fileOutput.write("\n")

The expected output:

function()=name=123
function1()=name1=1223

Instead the output looks like this:

function()
=name=123
function1()
=name1=1223

I can't figure out what is the problem. Can you give me a hint of what it could be ?

Where are you creating otherfunctionname ? How are you creating it? — Anand S Kumar

I'm creating it by parsing the line(before creating outputstring), I gave a general case — John Smith

probably functionname ends with a new line, strip that off. — wim

Try outputString = functionname.rstrip()+"="+otherfunctionname+str(lineNumber)
