R. David Murray added the comment: To clarify for the OP: in python3 the 'string' module does not contain a replace function, whereas in 2.7 it did. 'replace' is only a method on str in python3, whereas in 2.7 it is both an str method and a function in the string module. ---------- nosy: +r.david.murray _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue22792> _______________________________________
