Why doesn't Python (error msg) do the obvious thing and tell me
WHAT the actual (offending, arg) values are ?
In many cases, it'd help to know what string the var A had , when the error
occurred.
------------ i wouldn't have to put print(a) just above, to see.
( pypy doesn't do that either, but Python makes programming (debugging) so easy
that i hardly feel any inconvenience.)
i see that my example would be clearER with this one-line change:
> py bug.py
Traceback (most recent call last):
File "C:\Usenet\bug.py", line 5, in <module>
map( Func, fooBar( X, Y, X + Y
))
TypeError: can only concatenate str (not "int") to str
i hope that NOW a few of you can see this as a genuine, (reasonable)
question.
It tells me to go look at the function definition and how it's being
invoked. Even if I knew which of (X, Y) was an int and which a str, I'd
still need to do that.
Or you could add type annotations to your code and run mypy on it...
