I agree, this should not be done. However, sometimes it's useful to
see the parameter values:
import inspect
import logging
import sys
def log_fn():
logging.debug("%s%s" % (
sys._getframe().f_back.f_code.co_name,
inspect.formatargvalues(*inspect.getargvalues(sys._getframe
().f_back))))
logging.getLogger().setLevel(0)
def hello_there(x, y, z, *a):
log_fn()
return 1+x
>>> hello_there(1, 'a', 'b', 5, 6, 7, 8, 9)
DEBUG:root:hello_there(x=1, y='a', z='b', *a=(5, 6, 7, 8, 9))
It can be done, but usually you want to actually trace through with
the debugger.
