under naming

[David Bear]

I must have missed reading something important about naming conventions.

I have found that if I have a python module where I have an identifier named
with a beginning underscore that I cannot use from module import * to make
that name available in another module.

for example,
module A

_myvar = 'a local var'

module B
from A import *

_myvar -- is not available.

Is this in a pep somewhere ?

No; this has been a feature since before the time of PEPs. However, it is
documented here:
