What are the chances that could be made available from pure Python too?
Having to extract the name of the type is a very common need for error
messages, and I never know whether I ought to write type(obj).__name__
or obj.__class__.__name__. A %T and/or {:T} format code could be the One
Obvious Way to include the type name in strings:
raise TypeError("Expected int but got '{:T}'".format(obj))
looks nicer to me than either of:
raise TypeError("Expected int but got '{}'".format(type(obj).__name__))
raise TypeError("Expected int but got '{}'".format(obj.__class__.__name__))
