In a stack trace, is it possible to somehow get the arguments with
which each function was called?
So for example, if function `foo` in module `bar` was called with
arguments `(1, [2])` when it raised an exception, then instead of:
Traceback (most recent call last):
File "bar.py", line 123, in foo
build_rpms()
The stack trace would read:
Traceback (most recent call last):
File "bar.py", line 123, in foo(1, [2])
build_rpms()
This would save a lot of debugging time!
The cgitb module does exactly that; some third-party modules offer similar
functionality, but I don't remember any names.
Despite its name, cgitb works with any script.
Given this test script:
# begin test_traceback.py
import cgitb
cgitb.enable(format="text")
spam = []
def a(x, y):
"This is function a"
z = x+y
return b(z)
def b(z, n=3):
"""This is function b.
Its docstring is longer."""
if n!=3:
just(to_consume_space)
w = c(foo=z*n)
return w
def c(foo=0, bar=1):
"This is function c"
baz = foo+bar
spam.somenamethatdoesnotexist(foo+bar)
anotherglobal("thatdoesnotexisteither")
a(10, 20)
# end test_traceback.py
the output is:
AttributeError
