Modify the following as needed:

from inspect import currentframe, getframeinfo

def caller_info(depth=0):
	"""
	Get file, line number, and name of the calling function.
	"""
	if depth < 0:
		raise ValueError('invalid stack depth')

	caller = frame = currentframe()
	try:
		for i in xrange(-1, depth):
			caller = caller.f_back
			if caller is None:
				return (None, None, None)

		return getframeinfo(caller, 0)[:3]
	finally:
		del caller, frame
