HI. one thing confuses me. It is said in the pep3101 that "{}".format (x) will invoke the method x.__format__ However, I looked at the src of python3 and found: in class str(object), the format simply contains a pass statement in class int(object), things is the same.
So, what's the mechanism that "{}" works? Thx -- My gpg pubring is available via: gpg --keyserver subkeys.pgp.net--recv-keys 307CF736 More on: http://about.me/introom
