There would be cases where large dictionaries are being embedded in the code (multiple pages in length) and users might append something to end of the dictionary, just assuming that its not already in the dictionary.  This could be easily avoided by following dict() instead of {} notation for dictionaries. > > > a = { . . . 'a' : 1 , . . . 'b' : 2 , . . . 'c' : 3 , . . . 'd' : 'nextpage' , . . . 'a' : 0 . . . } > > > print a { 'a' : 0 , 'c' : 3 , 'b' : 2 , 'd' : 'nextpage' } > > > a = dict ( . . . a = 1 , . . . b = 2 , . . . c = 3 , . . . d = 'nextpage' , . . . a = 0 . . . ) File " <stdin> " , line 6 SyntaxError : keyword argument repeated

When the regex being compiled in python which has multiple wild cards like plus or asterisks sequentially repeated, you will need to escape or else run into "multiple repeat error". This can happen with any of re module methods like search and sub etc, where the regex is compiled. > > > import re > > > re . compile ( " r++ " ) Traceback ( most recent call last ) : File " <stdin> " , line 1 , in < module > File " /usr/lib/python2.7/re.py " , line 190 , in compile return _compile ( pattern , flags ) File " /usr/lib/python2.7/re.py " , line 242 , in _compile raise error , v # invalid expression sre_constants . error : multiple repeat > > > re . compile ( " r** " ) Traceback ( most recent call last ) : File " <stdin> " , line 1 , in < module > File " /usr/lib/python2.7/re.py " , line 190 , in compile return _
