Jerzy <jer...@genesilico.pl> added the comment: And anyway, for me it's not OK if something in a code of a function like 'del' affect how variables are affected in whole function.
It is really illogical. There code is in lines and line are one below another. The logical way is that a line of code affects the program ONLY when it is executed and ONLY from the time it is executed. A statement that is not executed (python never reach the place) should not affect the program in ANY way. You may think what you think, but for me it is a big bug in the heart of python Jerzy Martin v. Löwis wrote: > Martin v.
