If global (module-scope) variables are initialised by main, then those variables won't exist unless main() is run, which means that you can't use it as a module, only as a script. IMHO, global variables whose initial values can be evaluated without depending upon or modifying external state should be initialised at the top level. If a module has variables which cannot be so initialised, the module needs to provide an initialisation function which must be called explicitly by any program or module which imports it. -- https://mail.python.org/mailman/listinfo/python-list
