  So, why don't critical values get automatically printed out when
  exceptions happen?

  In Python, printing out a value usually means calling a method
  like "__str__" or "__repr__". But the thing is, the exception
  could have been raised inside that very method. If you then try
  to automatically print out a critical value, that could trigger
  more exceptions or other issues. Basically, you could end up
  activating all sorts of random code, and the consequences of
  that in that kind of situation are hard to predict
