New submission from Emmanuel Gamby: Hi,
Following the principle of least astonishment, I would expect the function to return the same value. Python 2.7.3 (default, Mar 13 2014, 11:03:55) [GCC 4.7.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import mimetypes >>> mimetypes.init() >>> mimetypes.guess_extension('text/plain') '.ksh' >>> mimetypes.init() >>> mimetypes.guess_extension('text/plain') '.asc' >>> mimetypes.init() >>> mimetypes.guess_extension('text/plain') '.txt' It seems that each call overrides the global dictionnary, which changes the iteration order of the next call.
