def capitalizeWords s     return re sub r  w    lambda m m group 0  capitalize    s    re sub can take a function for the  replacement   rather than just a string  which is the usage most people seem to be familiar with   This repl function will be called with an re Match object for each match of the pattern  and the result  which should be a string  will be used as a replacement for that match   A longer version of the same thing   WORD RE   re compile r  w     def capitalizeMatch m     return m group 0  capitalize    def capitalizeWords s     return WORD RE sub capitalizeMatch  s    This pre-compiles the pattern  generally considered good form  and uses a named function instead of a lambda

Potential library  https   pypi org project stringcase   Example   import stringcase stringcase camelcase  foo bar baz       gt   fooBarBaz    Though it s questionable whether it will leave spaces in    Examples show it removing space  but there is a bug tracker issue noting that it leaves them in

Note  Why am I providing yet another answer  This answer is based on the title of the question and the notion that camelcase is defined as  a series of words that have been concatenated  no spaces   such that each of the original words start with a capital letter  the rest being lowercase  excepting the first word of the series  which is completely lowercase   Also it is assumed that  all strings  refers to ASCII character set  unicode would not work with this solution    simple  Given the above definition  this function  import re word regex pattern   re compile    A-Za-z      def camel chars     words   word regex pattern split chars    return    join w lower   if i is 0 else w title   for i  w in enumerate words       when called  would result in this manner  camel  San Francisco      sanFrancisco camel  SAN-FRANCISCO      sanFrancisco camel  san francisco      sanFrancisco   less simple  Note that it fails when presented with an already camel cased string   camel  sanFrancisco       sanfrancisco   lt -- noted limitation   even less simple  Note that it fails with many unicode strings  camel  M  xico City        mXicoCity      lt -- can t handle unicode   I don t have a solution for these cases or other ones that could be introduced with some creativity   So  as in all things that have to do with strings  cover your own edge cases and good luck with unicode
