Extra line in output when printing inside a loop

Question

I can\'t figure out why the code #1 returns an extra empty line while code #2 doesn\'t. Could somebody explain this? The difference is an extra comma at the end of the code

Answer 1

There is a very simple fix for this.

Let's say I have, for arguments sake, a .txt file (called numbers.txt) which I am reading from with the values:

234234
777776
768768

Then, using the following code:

filename = numbers.txt

with open(filename) as file_object:
    for line in file_object:
        print(line)

Would give you the extra blank line as you are having problems with. But with a small change, you can get rid of the extra blank lines using the rstrip() method. So the code becomes:

filename = numbers.txt

with open(filename) as file_object:
    for line in file_object:
        print(line.rstrip())

Now you will get your results without those annoying blank lines between them!
