The perfect question for me.
You can suppress the exception context, that is the first part of the traceback, by explicitly raising the exception from None
:
>>> try:
raise KeyboardInterrupt
except:
raise Exception from None
Traceback (most recent call last):
File "<pyshell#4>", line 4, in <module>
raise Exception from None
Exception
This was formalized in PEP 409 and further improved in PEP 415. The original bug request for this was filed by myself btw.
Note that suppressing the context will not actually remove the context from the new exception. So you can still access the original exception:
try:
try:
raise Exception('inner')
except:
raise Exception('outer') from None
except Exception as e:
print(e.__context__) # inner
