Just take all the values, put them in a list, and use min() and max().
For example:

listofvalues = []
for pair in listofvaluepairs:

Thank you for your help, this is a very nice program but it does not
address the issue that I have values that do not overlap, for example
'c' and 'd' do not overlap in the above example and thus I would not
want to output 3-20 but the individual positions instead. In
addition, my inputs are not ordered from smallest to largest, thus I
could have a situation where a=5-9, b=15-20, c=7-10, etc., and I would
still want an output of: a.c = 5-10, b=15-20. I apologize for the
complication.
Thank you again!
Jay
That would be a bit more complicated...you might try using tuples of
values in a list, or writing your own class for the data handling.
Unfortunately that's not something I can just sit down and code in 5
minutes, it would take some careful thought and planning.

Defining dict as a module attribute ic correct, but try to answer the
following question:
Is dict1 an attribute/property/declension of the object/entity defined
by the module dicts ?
If yes, then your design is correct.
An correct example:
fruits.py
apple = {}
banana = {}
An incorrect one:
fruit.py
---
apple={}
bicycle={}
Basically, the rule is very straightforward, set your dict as a module
attribute only if its one of its attribute (very nice paraphrase !)
Most of people (including me) tend to have a module, where they put
everything they have no idea about their location. This is a bad habit
and result from a uncontrolled/undocumented design. Usually documenting
objects in such modules is really painful.
Your proposal is fine from a python syntax point of view. I can't tell
of your design with names like (dicts.py and dict1,dict2) hoping you do
not intend to name them that way.

Hi, Jean-Michel!
Thanks for your answer.
I am not going to have names like dicts.py and dict1,dict2. That was
just example. I wanted to know if it is correct to have dictionaries
on a module level. Now I know that this is correct. I want to collect
in one module a number of dictionaries, every of which describes a
separate web service. And my function in another module will import
required dictionary, depending on what web service should be used.
Thanks again for the help.
With regards,
Max.
(sorry if my English isn't very proper)
Yeah, you can put just about anything in a separate module/file, but
putting unrelated things in the same module is bad...
For example, if you have apple and banana in a module, and had a
function called slicefruit() to do something to those variables in there
with them, then that would be good. But if you put bicycle and car and
adjustbrakes() in the module with the fruits, or mixed the two groups in
several modules, that would be bad.

Actually, that would be very useful in the program from any suggestions to synchronize typed text and speech ?...i.e. have a dictionary key of (hour, minute, second).

I now have an application where I want to make notes during a conversation, but also want to record the speech during that conversation. I'm using Scintilla as a wxPython widget for editing and PyAudio for the speech recording, until so far everything works fine. Here the problem part: I need to synchronize the typed text with the sound during playback. So if I click somewhere in the sound recording, the line of text, typed that moment should be highlighted. And vise versa, if the cursor in the text is moved and some special key is pressed, the sound starting 10 or 20seconds earlier should be playbacked. I though of adding bookmarks (because these are fixed in the text), and keep a list of bookmarks and sound pointers. This idea should work, but there are only 31 bookmarks. Any other suggestions ? thanks, Stef Mientki That sounds like a very specialized type of thing, which only the few people with experience with wxPython, PyAudio, and Scintilla could help you with... But you might try having a dictionary with notes and associated times, or just give each note a four-digit ID number at the beginning of it when it's entered and use that in the dictionary (to keep keys shorter). Or you could just do a little hack and increase the number of bookmarks allowed (seeing as source is available) :p Marcus -- http://mail.python.org/mailman/listinfo/python-list

Re: Rus Python script interactively

In an interactive session (I am using iPython), what is the most
elegant way to run a Python script from Terminal? Right now I am
saying:
import subprocess
subprocess.call(python /path/to/scriptname.py, shell=True)
But I am calling a shell process and I'd rather not. The script just
runs, no inputs are needed. Is there a more Pythonesque method?

You could put the code of the script in a main() function and have an if
__name__ == '__main__': around the internal call. That way, it will
still run the code if you run it normally, and you can also run it
several times from the interactive session, ie:
file you want to run:
{{{
def somefunction():
print 'hello world'
somefunction()
}}}
file after modifications:
{{{
def somefunction():
print 'hello world'
def main():
somefunction()
if __name__ == '__main__': #only true if the file is being run normally,
not imported.
main()
}}}
Both of those, if run normally, will print hello world. If the first
one is imported, it will run once and not me runnable in that session
again. If the second one is imported, it will not do anything until you
call the main() function, and then you can call it again as many times
as you want:
{{{
import thefile
for i in range(5):
... thefile.main()
...
hello world
hello world
hello world
hello world
hello world
exit()
}}}
Hope this helps you!
