fCONV_AUSRICHTG is not defined - Why?

From Egon Frerich@21:1/5 to All on Tue Nov 7 18:47:26 2023

I've no idea why this happens. In a module there are lists and definitions:

    Felder = [
        # Name       lg1 lg2 typ   Ausrichtung Holen Prüfen Prüfvorg
        ["Jahr", 4, 5, "u", "", "right", "center"],

    ) = list(range(10))

Two lines with test statements follow and the statement which produces
an error:

    print(Felder)
    print(fJAHR, fNAME, fTYP, fCONV_AUSRICHTG)
    akette = "%" + "%".join(
        ["%s%s%s " % (i[fCONV_AUSRICHTG], i[fLG2], i[fTYP]) for i in Felder])

The traceback shows:

Works for me (Python 3.11 on Fedora-Linux 37)
- both as a script, and simple/single import.

What happens when you extract the second dimension's definitions into a
module of their own, and import that (with/out less-sophisticated join)?

The missing detail is this line from the traceback:

File "/home/egon/Entw/Geldspur/geldspur/gui/GUI_Konfig.py", line 11,
in <module>
class GUIcfg:

Here's a small example that shows the problem:

----8<----
#!python3.11
# -*- encoding: utf-8 -*-

class Test:
hello = "hello"
print(hello)
print([[zero] for _ in range(4)])
----8<----

and its traceback:

'zero' is visible in:

Something to do with how scoping is implemented in comprehensions?

Where do you define fCONV_AUSRICHTG? It must be initialized or defined somewhere. Did you leave out a statement from the python 2 version?

(fS1, fS2) = list(range(2))
fS1

fS2

NameError: name 'fCONV_AUSRICHTG' is not defined
You see "Felder" and with "0 0 3 4" the correct value 4 for
fCONV_AUSRICHTG. But there is the NameError.
What does <listcomp> mean? Is there a change from python2 to python3?

You are using a syntax that I don't understand, but "listcomp" means
a list comprehenson.

Where do you define fCONV_AUSRICHTG? It must be initialized or defined
somewhere. Did you leave out a statement from the python 2 version?

It's given its value here:

    (
        fNAME,
        fLG1,
        fLG2,
        fTYP,
        fCONV_AUSRICHTG,

        fHOLFUNKT,
        fPRUEFFUNKT,
        fPRUEF_ARG,
    ) = list(range(10))

This construction is a sneaky way to assign index numbers to list
entries. A simplified example:

>>> S1 = 'string 1'
>>> S2 = 'string 2'
>>> (fS1, fS2) = list(range(2))
>>> fS1
0
>>>
>>> fS2
1

You don't need the 'list', though: range(...) will work on its own.

Something to do with how scoping is implemented in comprehensions?

Yes, together with the way class scopes work during class construction.

Behind the scenes, the body of a listcomp happens to be implemented
as a nested function.

Usually you don't notice this, but while a class is being built,
its scope doesn't count as an enlosing scope for functions defined
within the class.

This is necessary, otherwise all of a class's attributes would be
visible inside its methods, which isn't what we want. However, it
leads to some odd corner cases, such as this one.

There are various ways you could work around this. I would suggest
moving the offending code outside the class and qualifying the
constants it uses with the class name.
