Both excellent points.

I suspect that Alain was just showing two ways to accomplish the same
end, since he was giving a purely didactic example. I dumbly copied his
code.
What about the following? Should the underscores be omitted from the
method names, for consistency with inspect?
# srcinfo.py
import inspect
import sys
def currentline():
return inspect.currentframe().f_back.f_lineno
def currentfile():
return inspect.currentframe().f_back.f_code.co_filename
# client.py
import srcinfo
import sys
debug = '-d' in sys.argv
# ...
if debug:
print('reached %s:%d' %
(srcinfo.currentfile(), srcinfo.currentline()))
