Given two modules, I've seen the following kind of strange behavior with list sorting on import and delete; a list that has been imported, sorted and deleted remains sorted on a second import: my_module.py: some_list = ['b','a'] other_module.py: from my_module import some_list print some_list some_list.sort() print some_list del some_list from my_module import some_list print some_list Output is: ['b','a'] ['a','b'] ['a','b'] Sorry if it's already been reported. |

That is not a bug in Python. The import statement merely adds a reference to the list into your module, so both variables point to the very same list (my_module.some_list is other_module.some_list). Therefore, any changes made to the list through my_module will also affect the list as seen from other_module. Closing the report as invalid. |
