Why is the exception not shown?

Question

Python

There is a wrapper class in the code for the page control object. When working with an object through with statement, no exceptions are thrown. Those .. if there is an error somewhere in the method, then the program simply exits the block. Why is that?

Answer 1

In general, I solved the problem by realizing that exceptions inside the block are passed to the magic __exit__ method , approx.

def __exit__(self, exc_type, exc_value, exc_traceback):

where you can then either handle the exception or pass it above.

Answer 2

Apparently the context manager, located in the statement, swallows exceptions. It is impossible to say anything more precisely on the current formulation of the question.
