Python 2.x Print vs 3.x Print

[ghost]

I am in no way a python expert, nor have I ever written my own script, but you claim that your script is 2.7+ capable and I don't think that's the case. I'm sure that doesn't only mean 2.x variants, but could be wrong.

Believed to have confirmed my guess as:

  File "downloader.py", line 144
    print 'Downloading Youtube comments for video:', youtube_id
                                                  ^
SyntaxError: invalid syntax

EDIT: works great on 2.7! Thanks!

Also I tried updating print to 3.x syntax and it appears there is more than print being the problem. Is it possible to make a script that reads user python version and acts accordingly?

This worked for me on 3.6.1. I ran 2to3 (Python's 2.7 converter to 3.x) and below is what I needed to change. `xis-MacBook-Air:YT xi$ 2to3 downloader.py RefactoringTool: Skipping optional fixer: buffer RefactoringTool: Skipping optional fixer: idioms RefactoringTool: Skipping optional fixer: set_literal RefactoringTool: Skipping optional fixer: ws_comma RefactoringTool: Refactored downloader.py --- downloader.py (original) +++ downloader.py (refactored) @@ -139,19 +139,19 @@ parser.print_usage() raise ValueError('you need to specify a Youtube ID and an output filename')

• print 'Downloading Youtube comments for video:', youtube_id

• print('Downloading Youtube comments for video:', youtube_id) count = 0 with open(output, 'wb') as fp: for comment in download_comments(youtube_id):

• print >> fp, json.dumps(comment)

• print(json.dumps(comment), file=fp) count += 1 sys.stdout.write('Downloaded %d comment(s)\r' % count) sys.stdout.flush()

• print '\nDone!'

• print('\nDone!')

• print 'Error:', str(e)

• except Exception as e:

• print('Error:', str(e)) sys.exit(1)`

You will get an error like this "Error: a bytes-like object is required, not 'str'". This just means you need to remove the 'b' in 'wb'.

Thanks! & Happy Coding!

@hairypaulsack You're right only Python 2.7 was supported,

@d0tN3t Using your suggestions, I've just added Python 3 support. Thanks!
