Subclass str: where is the problem?

Hello, can anybody explain/help me: Python 2.4.2 (#2, Sep 30 2005, 21:19:01) [GCC 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu8)] on linux2 class Upper(str): def __new__(cls, value): return str.__new__(cls, value.upper()) u = Upper('test') u 'TEST' type(u) u = Upper('') u '' type(u)

Re: Subclass str: where is the problem?

This is good... try this: value = 'test' value 'test' type(value) value = type(value) is type('') and Upper(value) or value value 'TEST' type(value) value = 1 value 1 type(value) value = type(value) is type('') and Upper(value) or value value 1 type(value) -- http://mail.python.org/mailman

Re: Subclass str: where is the problem?

Effectively. Thanks a lot Peter and Harold. -- http://mail.python.org/mailman/listinfo/python-list
