How to get value of arguments passed to functions on the stack?

Question

Using:

traceback.print_stack()

I can get:

  File \"x.py\", line 20, in 
    y(x)
  File \"x.py\", line 11, in

You can use the inspect module for this:

>>> import inspect
... def fn(x):
...     try:
...         print(1/0)
...     except ZeroDivisionError as e:
...         frames = inspect.trace()
...         argvalues = inspect.getargvalues(frames[0][0])
...         print("Argvalues: ", inspect.formatargvalues(*argvalues))
>>> fn(12)
Argvalues:  (x=12)
