Code leaving random string at end of output

Question

So i have made the code and it all checks out but when i run it, you would have to create your own text file, i get the random output of (1, '\n'). I cant explain it properly because im quite new so i hope the code helps.

I have got what i expected to happen however at the end of every line that is printed to the user, the annoying (1,'\n') appears as well.

yes sure. It is a text file by the name of Earth.txt inside it is this: aaaabbdffee ccrrffddgfdss — , Sep 27 '19 at 09:20

The file.readline method always returns a string with a trailing newline character (unless it's at the end of file and the file does not end with a newline character), so you should use the str.rstrip method to remove the trailing newline character before processing the string:

line1 = f.readline().rstrip('\n')

Careful, as this may also remove any spaces at the end of the line. – 9769953 Sep 27 '19 at 09:22
I've updated the code so that it will only remove trailing newline characters then. – blhsing Sep 27 '19 at 09:25

f.readline()

Reads each line in the file, including empty lines, for which it will just return the linebacker ('\n'). Usually you don't see it because print() handles it automatically, but your function counts this as a separate character. See if you have any empty lines at the end of your file, and just backspace them and save. Hope this helps.
