Hello,
I would like to raise an exception of type Exception(), however the
regular exception stack trace needs to be supressed.
This is needed in a function that takes raw_input() from the
user and
based on 'Y' or 'N', the function suspends further execution and
returns
to the python prompt or Hicontinues. An exit() brings it out of
the python
processwhere as what is needed is coming back to the python
prompt.
I want a custom message to appear instead of a regular exception
stack
trace message.
How to do this? any pointers...?

Forgot to mention that we are currently stuck with python2.5.2
As part of a debug/test hook, I would like to suspend further action of
a program, after a certain point in the procedure. What I had come up
with is a function named testHook() which does this:
def testHook():
"""
"""
choice = raw_input("Would you like to continue (Y or N): ")
try:
if(str(choice).lower() != 'y'):
print("You chose not to go ahead. Ok!!\nAborting Now...")
raise Exception("User initiated Abort...")
except Exception:
raise # re-raise it..so we come out of execution loop
In this case, a stack trace gets printed out, before the string 'user
initiated abort' comes up. I want to remove that stack trace...so it
looks more clean to a user.
What can be done in this case?
Well, I don't understand how and from what context you are calling testHook().
My first instinct is to ask, why you can't simply return instead of 'raise' on
an abort ? like so ...
def testHook(exc):
choice = raw_input("Would you like to continue (Y or N): ")
if(str(choice).lower() != 'y'):
print("You chose not to go ahead. Ok!!\nAborting Now...")
print "User initiated Abort..."
return -1 # ...or any other value that makes sense to your app.
else:
raise exc # re-raise the passed exception
In which case, I am assuming testHook() called like this:
try:
1 + "foo"
except Exception, e:
return testHook(e)
or any other way of creating such a hook?
Yes. The way I would do this sort of this is by using decorators:
>>> def testHook(func):
... def wrap_exception(*args):
... try:
... func(*args)
... except Exception, e:
... choice = raw_input("Would you like to continue (Y or N):
")
... if (str(choice).lower() != 'y'):
... print("You chose not to go ahead. Ok!!\nAborting
Now...")
... print "User initiated abort ..."
... print "on recieving %s" % e.message
... return
... else:
... print "redirect to debugger in this block ..."
... return wrap_exception
...
>>> @testHook
... def main(a, b):
... return a + b
...
>>> main(1, "foo")
Would you like to continue (Y or N): n
You chose not to go ahead. Ok!!
Aborting Now...
User initiated abort ...
on recieving unsupported operand type(s) for +: 'int' and 'str'
>>>
Here is a good article for introducing decorators:

[BangPypers] Help Python framework for report creation (bar graph, pie etc)
Hi all, I'm relatively a newbie to python. But i do read most of the posts in this list. Currently I'm doing a study on developing one reporting framework to pull the data from the database and project in appealing way like pie charts, normal charts, bar graphs etc. Would any body please comment on some good frameworks in python (web based GUI), which is already available on which i can add my customizations. This is to replace one of the reporting frameworks provided by Business Objects Web Intelligence. Any comments on where to start, how to start are much appreciated. Please help.

Re: [BangPypers] Help Python framework for report creation (bar graph, pie etc)
For plotting you can use gnuplot or pychart. Now for my project I used both gnuplot and pychart , but went with pychart since the latter is easier to integrate with a web-framework. I can ask pychart to give me the output in a PNG format and I can use that in a web page. The documentation of pychart are pretty simple and straightforward. -Hope This Helps Santhosh On Wed, Sep 16, 2009 at 7:48 PM, Jins Thomas wrote: > I'm relatively a newbie to python.

Doesn't pygooglechart require you to fetch images from google severs every time? This also reminds me of YUI charts which recently(v2.8) added Dual axis chart support.
