The point is Exceptions are made for error handling, not for normal
workflow. I hate when i read that for example:
try:
do_stuff(mydict[k])
except KeyError:
pass
I as well, but for other reasons (see below). But basically this is EAFP.
(loads of them in many libraries and frameworks)
instead of:
if k in mydict:
do_stuff(mydict[k])
This is LBYL, C-style, not Pythonic.
I would do
try:
value = mydict[k]
except KeyError:
pass
else:
do_stuff(k)
Why? Because do_stuff() might raise a KeyError, which should not go
undetected.
