"Breaking" the __main__ script

[vsoler]

Hello,

I am still learning python, thus developnig small scripts.

Some of them consist only of the main module. While testing them
(debugging) I sometimes want to stop the script at a certain point,
with something like stop, break, end or something similar.

What statement can I use?

Something like
import sys
sys.exit()?

HTH.

Or just "raise SystemExit", "raise SyntaxError" or any other Exception.
But you won't have to: If you use IDLE, you can just set breakpoints in
your code: enable the debugger in debug-debugger and set breakpoints via
right click in your source file.

Or you could use a real debugger, like pdb

I think it's less than likely that it will help, since once sys.exit()
is called the program is no longer available for inspection.

The OP is probably looking for the "pdb" module in the standard library.
The documentation is good enough to get you started.

Hola Vicente,

You need a debugger.
A practical solution to start with is to use an IDE with an integrated
debugger.
Stani's Python Editor (SPE) is a lightweight IDE with pdb integrated
(with style checker also).
It is a very good ide for learning (simple and not cluttered) but also
for medium size
applications (it is very well designed).

Any reason you prefer PDB over WinPDB?

Thanks,

I always count "in the standard library" as a big plus over any
add-ons It's nice to know about alternatives such as WinPDB, but
everybody that has python also has pdb already installed.

WinPDB runs on non-Windows platforms

Sorry, i hit the wrong key. Again:
winpdb is crossplatform. It uses a wxwindows gui.
Names are not really fortunate...
I have installed the last winpdb 1.4.6 in SPE today.

Uh, OK.
Then the name mislead me

But yeah, I prefer a console based debugger.

One might reasonably argue that it has a pretty couter-intuitive name, then.

'Win' may stand for Winner, not Windows

import bdb

pdb.set_trace() # put this line anywhere you want a breakpoint in your code.

type n for next, c for continue, s for step into and google for 'python
pdb' for the details.
