problem reading a CSV file

2021-12-13 Thread Larry Warner

error on open statement

Probably simple error but I do not see it.

The program is a python example with the file name being changed.  I want
to experiment with changing the literal file name in the open statement to
a variable name later.

I hadn't realised effbot.org was 'on hiatus'. Yes, definitely worth
bookmarking The Wayback Machine backup - or even (someone?)
making a separate archive?

Installation problems

2021-12-13 Thread Cristiano Loro
Good morning,
i am using a python application to program ESP8266. in my office everything 
works fine, but in production, where users don't have the same access 
privileges, I can't get it to go. In production I performed a custom 
installation defining "for all users", but the modules are placed elsewhere and 
this is perhaps the problem. How can I put the modules in the correct folder? 
in general how can I get around the obstacle
many thanks in advance for your help

Use forward slashes "/" instead of backslashes "\".

It's difficult to say what the problem is when you haven't given us the 
code!

Note: Attachments do not make it to this list.
You will need to insert the code into the message as text.

How are you installing the modules?

Are you doing it with sufficient privileges to put them in the
shared area?

Are you sure that your users are running the same Python that
you installed?

Any hints welcome ...

During interpreter shutdown, all kinds of things can go weird. The
order that things get destroyed isn't always clearly defined.

Is it possible to do the cleanup work before interpreter shutdown?
Alternatively: maybe take a local reference to the exception types you
need to refer to (just "AttributeError = AttributeError" at top level
should do it), which should keep them alive longer (I think). Worst
case, capture *all* exceptions, then look at e.__class__.__name__ and
match on that.

OK - not solved but resolved anyway.

The Django project was failing on the new server and working fine in dev.

The problem seems to be a mis-export from an old subversion repo.The 
project was being reconstituted on a new staging server from a reloaded 
svn dump from the old (ancient) svn server to the new svn server on the 
same machine.


Resolution "happened" when I updated the (c) notice in all source files 
and recommitted to the new server and re-exported from that. The repo 
looks fine. The log is all there back to the beginning. As a test I have 
deployed from an earlier revision and that all works. It's either a 
miracle or I did something else (which I didn't notice) which fixed it.


Thanks to everyone for thinking about this.

Cheers

Mike
