exec-function in Python 3.+

[Hans Larsen]

Help!
I'm begginer in Python 3.+!
If i wih to update a module after an import and chages,
How could I do:
By "from imp import reload" and then reload(mymodule)
or how to use "exec(?)", it is mentoined in docs.
In Python ver. <3 reload(module) writes something back to interpretter!,
how about exec, which is a function?-
I,m thanking on the help!!

What makes you think you need to 'reload' a module. If you don't know
exactly what you're doing (by saying you're a beginner I'm guessing
not...), and aware of the consequences that can follow... I would say,
*don't*. There's too much to bite you in the rear (and not a blatant
bite from a lion, but rather a playful little kitten that then plays
cute and exudes a "moi?" expression).

Also, it may help others to post their thoughts if you tried to
describe why you think you want to go down this line, and what you're
trying to achieve.

Jon.

I've never used reload() in 2.x or 3.x. If I'm debugging interactively
with the command line interpreter and I get to this point, I exit() and
start the python interpreter again. And if there was too much typing to
waste by doing that, I write the code into another script, and run that
from an IDE. From most IDE's, you get a fresh chance every time you
start a run.

I haven't found any reason to change this behavior. So if you have a
use-case, please elaborate. And know that there are lots of traps in
reloading a module, as it can't really eliminate all traces of being
already run once. It works for simple stuff, but you don't need it for
simple stuff,... And I guess I'm repeating myself.
