Nested if statements with same else expressions in python

Question

I am wondering whether there is a nice solution in python for nested if statements where all else have the same expression, without having to rewrite that expression?

In the example below I rewrite expr3 for both else statements:

if cond1:
 expr1
 if cond2:
 expr2
 else:
 expr3
else:
 expr3

The issue above is that expr1 is conditional on cond1, but not cond2. Unless there is something like an "all else" expression, the only simplification I see at the moment, is to break it into two statements:

if cond1 and cond2:
 expr2
else:
 expr3

and

if cond1:
 expr1

Would be glad to see any other suggestions!

Answer 1

This might help.

setExp3 = True
if cond1:
 expr1
 if cond2:
 expr2
 setExp3 = False
if setExp3:
 expr3

• user3485516: Using a boolean setExp could be useful to shorten the code!

Answer 2

I'd rather do it differently:

if cond1 :
 expr1
 if cond2 :
 expr2
if not (cond1 and cond2) :
 expr3
