Hi all,
I had the same sort of question as Wildemar and I set about
investigating as any good pythonista would by typing help(apply) at
the interactive prompt. That produced a help text that started:
Help on built-in function apply in module __builtin__:
But:
>>> [x for x in dir('__builtin__') if 'apply' in x]
[]
? If apply is in the __builtin__ module, why doesn't
dir('__builtin__') know about it?
Best to all,
Brian vdB
