How to fix this line breaks?

Question

Im creating a new file which has the data from other file, and i have to add extra information. The code runs okay but when i open the file the data that i add messes up the file structure.

def writeSalary(fileName):
    f = open(fileName,"r")
    g = open("Personas2.txt","w")
    for line in f:
        line=line[:-1]
        g.write(line)
        g.write("1000\n")
    f.close()
    g.close()

The expected output is:

Answer 1

Just change line=line[:-1] to line=line.rstrip().
