Summarizing the answers, it seems that I will try to follow three
suggestions:
3) If I define a few values intended to be used very locally, delete
those after use.
Why bother? Unless they're big objects and you want to ensure they get
deleted as soon as possible.
To ease debugging.
Perhaps the problem only appears because I use longer functions than
recommended for python, but I have functions containing 2 to 4 loops,
with several if-clause each, where the different parts use very similar
variable names, like x, y, z, dr, dr_2, dr_3 etc.
None of the code fragments uses all of the names, but every fragment
uses some of them. I have had typos that incorrectly reused values from
a previous fragment. In those cases, it would have been much easier to
debug a raised exception due to using an undefined name, than to debug a
slightly incorrect result due to some if-clause of some loop computing
with an incorrect value.
