I ran

pip install better-exceptions-hook

For both Python2 and Python3, and then ran the following file (bla.py):

a = "hello"
b = "world"
assert a == b

Here's the output:

erez@localhost ~ $ python2 bla.py 
Traceback (most recent call last):
  File "bla.py", line 4, in <module>
    assert a == b
           │    └ 'world'
           └ 'hello'
AssertionError: assert a == b

erez@localhost ~ [1]$ python3 bla.py 
Traceback (most recent call last):
  File "bla.py", line 4, in <module>
    assert a == b
AssertionError

Any idea why?

I'm unfamiliar with import hooks and the standard library documentation does not mention where to place .pth files. How would I go about installing this?

Thanks, this sounds very promising!

You don't actually need to provide a separate better_exceptions_hook module, your pth file can just contain

import sys; exec('try:\n import better_exceptions\nexcept Exception: pass')

(The sys import is just a placeholder needed for the pth file to work.)

I got the trick from https://github.com/ionelmc/python-hunter/blob/master/setup.py#L47; see https://github.com/anntzer/mplcursors/blob/master/setup.py for a self-contained solution. (Here the embedded string is so short that you can probably just hard-code it.)
