5.1.0 WidgetGen FileGenerator.py

[seasoned_geek]

All,

I got back to working on this late today and ran smack dab into this.

It would sure help if the error message printed what it actually couldn't find and the file it couldn't find it in.

Let me say I do very little Python and try to avoid doing it no matter what.

Using Meld on Ubuntu 20.04 LTS (where I'm working on the CopperSpice port) shows this to be a shiny new if statement in FileGenerator.py.

Was that print statement supposed to look like one from this example?

https://stackabuse.com/writing-to-a-file-with-pythons-print-function

====

import sys

print('This message will be displayed on the screen.')

with open('filename.txt', 'w') as f:

    print('This message will be written to a file.', file=f)

====

I assume there is something else I'm missing when diffing the directories in Meld but it is not jumping out at me. It could jump out at me if I knew what was being looked for in which file.

Any help would be appreciated.

Thanks in advance.

Most likely due to using an older version of Python, probably 2.7, which doesn’t support f-strings (the ‘f’ before the double-quote), instead of 3.8. It may be possible to run Python 3.x with a “python3” command.

Yes, that is what it is trying to do.

While the code could be changed to work with Python 2.7, its likely that similar issues will occur next time its changed.
