ExceptionCatcher

General wrapper for catching exceptions

Any exception (Except for KeyboardInterrupt and SystemExit) raised inside ExceptionCatcher context will be caught and suppressed and the whole traceback will be printed out.

Usage

As decorator

@ExceptionCatcher
def foo(a):
    raise BaseException

@ExceptionCatcher(callback=lambda: 42)
def bar(a):
    return 1 / a
    
print(foo())   # None
print(bar(0))  # 42
print(bar(1))  # 1

As context manager

with ExceptionCatcher:
    raise BaseException

with ExceptionCatcher(callback=lambda: 42) as catcher:
    raise BaseException
    
print(catcher.failed)  # True
print(catcher.result)  # 42
