Replace line

I want to write a program that gives some integer value. I have a file with a value in the first line. How can I change the value of line (for example to 12). in my code, but this gets a value and I want to go to line 2 and addition m to that number in line 2 but it doesn't work

@jan markus with open('pash.txt', 'r') as f: lines = f.readlines() m = 5 # value you need to add to a line. o = 2 # line number of the line to modify. with open('pash.txt', 'w') as f: for x, line in enumerate(lines): if x == o: line = int(line) + m f.write(line)
