Is there any way to check if an item in specific location in a multiple
dimension nested exist? For example something like:
if M_list[line][row][d] exist:
do_something_0
else:
do_something_1
Certainly:
<code>
try:
M_list[line][row][d]
except IndexError:
do_something_1
else:
do_something_0
</code>
Assuming that you want to check because something in `do_someting_0' fails
if the item isn't defined, it is very likely that this can be shortened to:
<code>
try:
do_something_0
except IndexError:
do_something_1
</code>
The try/except should be wrapped as tightly as possible around the specific
code that actually throws the exception.
