[ How to find a group of consecutive leters and check cases with python re ]

How can I do a re.findall() that looks for a group of 7 letters where the first 3 and the last 3 are all uppercase and the one in the middle is lowercase? So far, I've tried this:

word1 = "".join(re.findall("[A-Z][A-Z][A-Z][a-z][A-Z][A-Z][A-Z]\d{3}","mystring")]

However, it doesn't output anything.

How can I do this query?

Thanks!

Well, this works for me

p = re.compile(r"[A-Z]{3}[a-z][A-Z]{3}")

word = "".join(re.findall(p, 'udkehtEOajidfEEfjaiERBdEHY alijdfilaOEPvOEG'))

output:

>>> print word
'ERBdEHYOEPvOEG'

Of course, if you were actually searching in "mystring", you would naturally get no matches.
