You may want to read the pages on regular expressions in the online documentation: http://www.python.org/doc/2.5/lib/module-re.html The simple approach works: import re # Open the file f = file('/your/filename.txt') # Read the file into a single string. contents = f.read() # Find all matches in the string of the regular expression and iterate through them. for match in re.finditer(r'\([A-Z].+[a-z]\)', contents): # Print what was matched print match.group() -- http://mail.python.org/mailman/listinfo/python-list
