Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Zac Evans (karadoc) Assigned to: Nobody/Anonymous (nobody) Summary: Option to force variables to be declared Initial Comment: My most common python programming error is to spell a variable different ways in different parts of a program. Often this generates no warnings, and is a difficult problem to track down. The Zen of Python says that 'Explicit is better than Implicit'. I would like it if I could set an option so that I had to explicitly declare variables before I can use them. eg. x = 5 would generate a warning, but x = int() x = 5 would not. I do believe that explicit is better than implicit with respect to programming; and I know that this feature would save me a _lot_ of debugging on my larger python projects. ---------------------------------------------------------------------- Comment By: Jim Jewett (jimjjewett) Date: 2005-02-15 12:57 Message: Logged In: YES user_id=764593 For various reasons, this won't soon get into the core. Meanwhile, there are some tools like pychecker which may help. I've also found that declaring __slots__ makes the errors surface a little bit faster, when I'm dealing with attributes. (The most common reason for me to need the variable name in widely separated places.) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=355470&aid=1122279&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
