Hi,
I read that we can use "%f" to format a float number output. Could somebody tell me that if I can use "%s" to format a string to make an output from '2001-5-12 13:22:00.00' to '2001-5-12 13:22'?
Thank you.
Jenny

%s does exist, but it won't really help you for that. As far as I know,
the % operator won't let you cut characters
Why don't you just slice it?
'2001-5-12 13:22:00.00'[:-6] -- > '2001-5-12 13:22'
or
'2001-5-12 13:22:00.00'[:15] -- > '2001-5-12 13:22'
This is more Python like anyways

exactly. some other options:
split and join (see:
http://www.python.org/doc/current/lib/string-methods.html )
s = '2001-5-12 13:22:00.00'
s.split(":")
['2001-5-12 13', '22', '00.00']
":".join(s.split(":")[:-1])
'2001-5-12 13:22'
If you want to do something really fancy, you could use regular
expressions:
http://www.python.org/doc/current/lib/module-re.html#l2h-663
and
http://py-howto.sourceforge.net/regex/regex.html
If you want to manipulate times, I highly reccomend mxDateTime:
A general note: wxWindows is intended to be a complete cross-platform
application framework. Python is already has a pretty complete set of
tools for cross platform develpment, with teh exception of GUI stuff.
That's we wxPython comes in, so, as a rule, if it GUI related, look for
a wxPython solution, if it is not GUI related, look for a "pure" python
solution.

If you can, print out the Python library reference, and look through
that. Lots of interesting toys, including routines to manipulate date
and time. For example, try:
from time import * # Play with dates
from string import * # Monkey with strings
now = localtime(time()) # Current time: yyyy,mm,dd,hh,mm,ss,wd,jd,DST
yyyy,mm,dd,hh,nn,ss,wd,jd,dst = now
print strftime("%a %b %d %H:%M:%S %Y",now)
Tue Jul 17 19:11:52 2001
The localtime returns a tuple with the following values:
(Year,Month,Day,Hour,Minute,Second,WeekDay,JulianDay,DaylightSavingsFlag)
strftime() formats the time tuple in many different ways.
