When it is a constant.
pyLint sees that you are assigning a numeroc literal and 
so thinks that this may be a definition of a constant value.

If you disd someting like

A = 8
az = A

It may well be happy since A is a constant and the variable 
is being assigned the constant rather than the literal.

All lint tools are by tradition very exacting, even the C version 
which pyLint is modelled on is notorious for throwing irrelevant 
errors - like not checking the return value of a printf() function 
(printf returns the number of characters printed but virtually 
nobody ever checks that!)

As another poster said treat it in the spirit it is intended, 
a tool to highlight *possible* causes for concern not definite 
causes.
