Consider the following snippet:
def foo(a, b): pass foo(1, 2, 3)
We all know what will happen.
File "<stdin>", line 4, in <module> foo(1, 2, 3) TypeError: foo() takes 2 positional arguments but 3 were given
Would it be reasonable to include the line number for the function `foo()` that it resolved the call to? I.e. 'File "<stdin>", line 1, in foo'.
There are situations (e.g. monkey patch) where this is not obvious. Would be great detail to include that in the traceback, I think.
That was reported some time ago:
Just as you, I had hard time to believe that wasn't fixed over 30 years of CPython history.
I fixed that in my Python dialect, https://github.com/pfalcon/pycopy , and enjoyed it thoroughly on multiple occasions since then. For the snippet above (put in a file):
Traceback (most recent call last): File "ex.py", line 4, in <module> File "ex.py", line 2, in foo TypeError: foo() takes 2 positional arguments but 3 were given
