But the implicit global variable access seems quite uncomfortable to

I have Google the whole thing and find another way for alternative
implementation of getting the function's name. But all they returns are
just strings. If I would like to refer to the function object in order
to call it recursively, what shall I do then?

When debugging using 'print' statement, I usually want to print some

Since every function object actually has a private __name__ attribute

Yes, I checked out that I have already run "from string import *". So
the lower() means string.lower() function.
However, something else came out just now:

'b'

'A'
>>>instr
'a'
Both as the method of the type str, join never use the instr instance

In python, these expression seems yields the same result:
