Irit Katriel  added the comment:

You don't need sys.exc_info() for the traceback anymore.

except Exception as e:
raise OSError('blah').with_traceback(e.__traceback__)

[issue47099] Replace with_traceback() with exception chaining and reraising

[Oleg Iarygin]

New submission from Oleg Iarygin :

Currently, exception chaining in Lib/ modules is implemented with pre-3.11 
`raise Foo(...).with_traceback(sys.exc_info()[2])`. However, this approach can 
be simplified:

1. PEP 3134 introduced a proper `raise Foo(...) from bar` construction that 
takes a parent exception instead of its stack traceback

2. Without the traceback required, we partially get rid of `sys.exc_info` thus 
reducing active tapping into global internals

A report printed into a console remains the same except a line:

> During handling of the above exception, another exception occurred

replaced with:

> The above exception was the direct cause of the following exception
