# obtaining the name of a function/method

# the following function might be implemented in the
# sys module, when generators are introduced.
# For now, let's emulate it. The way is quite inefficient
# since it uses an exception, but it works.

import sys

def _getframe(level=0):
    try:
        1/0
    except:
        import sys
        tb = sys.exc_info()[-1]
    frame = tb.tb_frame
    while level >= 0:
        frame = frame.f_back
        level = level - 1
    return frame

sys._getframe = _getframe
del _getframe

# we now assume that we have sys._getframe
