Python Using Databases in Python Our Diary App Doing Data Entry

To get ./diary to work on windows I used #!/usr/bin/env python

The only installation of Python I have on my machine currently is Python3. If I had python2 as well though then I would probably need to specify which version I wanted to run though right?

The "shebang" (or "hashbang") is a Linux/Unix program loader directive. I would not expect it to be effective on a Windows system.

this is not working in workspaces - /usr/bin/env: 'python3\r' No such file or directory

Try it without the "\r".

it was without the \r - that was part of the return error

In that case, it sounds like your file is in Windows text format (CR/LF) and not Linux format (LF only).

this was in workspaces - though I found workspaces to be very cachey (?) sometimes if you run the exact same code in a different session and it will pass

The workspaces use Linux. A "\r" is a return (CR) character, which should not be part of a Linux text file.

Steven - I just used the she-bang on a file I'm using now Python Testing - Writing and Running Doctests and it worked.. I let you know if I see the \r again

  • I was in workspaces though (no "fake news" ;) )

Steven Parker - can you have a look at /decorators/dec.py in that workspace https://teamtreehouse.com/workspaces/39916452#

You can't share a direct link to a workspace, it's temporary and only exists while you are using it. But you can make a snapshot and share the link to that.
