[Tutor] Python Debugger shortcut to go to the last frame
Hi
Please consider the following script:
#!/usr/bin/env python3.6
#pdb_last_frame.py
import pdb
def recursive_function(n=5, output='default print'):
if n > 0:
recursive_function(n - 1)
else:
pdb.set_trace()
print(output)
return
if __name__ == '__main__':
recursive_function("space ham")
For instance we run it as
python3.6 -m pdb pdb_last_frame.py
The following command sequence applied once the script stopped on bp:
u
u
The question is there any command to go directly to the last frame instead of
typing d d ?
Thank you in advance.

[Tutor] Python debugger/IDE that can be launched from a remote command line
I am working on a project in which the code and data I am working with are all on an Amazon EC2 machine. So far I have been ssh'ing to the EC2 machine in two terminal windows, running emacs or vi in one of them to view and update the code and running the python -m pdb ... debugger in the other one to step through the code. I would prefer to work with an IDE that displays and updates program state automatically, but I don't know which ones I could launch from a remote machine and have it display within a terminal window or use XWindows or GTK to display in its own window. Are there any Python debuggers or IDEs that can be used in this kind of setting? Thanks, Mike ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Python debugger
It might and I'll keep it in mind. However, I'm not going to ditch my linux just to get a gui debugger. After all, I do have WingIDE installed in Linux, but I wanted to be free of the GUI limitations I have when I code on a host that I connect to through a minicom on another ssh host. I do that from time to time. Thanks anyway. I got what I needed. :-) /Michael On Fri, Jan 9, 2009 at 3:14 PM, Kent Johnson ken...@tds.net wrote: On Fri, Jan 9, 2009 at 7:36 AM, Michael Bernhard Arp Sørensen mich...@arpsorensen.dk wrote: I can't use a graphical debugger because i mostly code python over ssh on remote servers in my company.

[Tutor] Python debugger
Hi there. I've just started using the python debugger and I wonder how I could have lived without it earlier. I just wonder if there is a smarter way to show what all the variables contain in any given point in the debugger. I'm using this approach: import sys f = sys._getframe() p f.f_locals.items() It's not exacly pretty in its output, but it's better than nothing. Can this be done in a smarter way? -- Kind regards Michael B.

'a' will show the arguments to the current function; not the same but shorter. p locals().items() is probably the same as what you are doing. You might want to look at a graphical debugger such as winpdb. Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] Python debugger bummer
Hi to all, I tried to look for a reference to this issue in the ASPN archive, but I can't seem to find an answer. I currently work under Linux and have never been able to properly use the Python debugger. Coming from a Perl background, I fail to find a similar simple way to step through my code the way I am able to do it through the -d flag using Perl on the command line. It is so painless. I have used Python on Windows, usually writing my programs using Vim, and entering the PythonWin environment to debug my programs. It is a good environment to do that, although I prefer my independent editor for writing my programs. I once paid for ActiveState's Komodo for Linux to use as an IDE, but I find it bloated and slow, not to mention the need to constantly upgrade if you want to keep up with versions (have not done it yet). Does anyone have any suggestions as to an alternative to PythonWin, or even better still, a reference to a good tutorial on how to use my current tools: how to use the python debugger as the way Perl debugger works? I am certain the Python interpreter (being better that Perl in that sense) must have a way to use the debugger. I work under Linux using vi/gvim and ipython (I have never really tried IDLE). Thanks in advance for any help. Victor ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi again, I was going through the Python library documentation and I found something I never saw before. $ python -m pdb myscript.py This is what I was looking for! Great help. Any further reference could of course help a lot. I never was able to get the hang of it until now.

I was going through the Python library documentation and I found something I never saw before. $ python -m pdb myscript.py I was just about to suggest loading pdb...

The paper version of my book contains a chapter (not on the web site) on how to use pdb to debug a script. pdb has its limitations but if you are used to gdb then its not too bad.
