Two ways (at least):
(1) check out the strptime and strftime (p == parse, f == format)
functions in the time module
In general, the datetime module is much to be preferred for working with
dates and times -- unless of course you need to mimic functions from the
C time.h library -- however the datetime module won't be getting a
strptime until version 2.5, which is still in alpha test.
(2) As you are new to Python, you might like to try your skills with
basic parts from the Python toolkit, like dictionaries and slicing, and
write a function yourself, specialised to that particular format. Here
are some hints:
# example Dec 06, 2000
# ruler 0123456789012
mpart = data[0:3]
# similarly: dpart, ypart
month_dict = {'jan': 1, ....., 'dec': 12}
month_num = month_dict[mpart.lower()] # will work with Dec, dec, DEC
result = '%s-%02d-%s' % (ypart, month_num, dpart)
How much validation you do is up to you :-)
