How to exit an if clause

Question

(This method works for ifs, multiple nested loops and other constructs that you can't break from easily.)

Wrap the code in its own function. Instead of break, use return.

Example:

def some_function():
    if condition_a:
        # do something and return early
        ...
        return
    ...
    if condition_b:
        # do something else and return early
        ...
        return
    ...
    return

if outer_condition:
    ...
    some_function()
    ...

from goto import goto, label

if some_condition:
   ...
   if condition_a:
       # do something
       # and then exit the outer if block
       goto .end
   ...
   if condition_b:
       # do something
       # and then exit the outer if block
       goto .end
   # more code here

label .end

(Don't actually use this, please.)

while some_condition:
   ...
   if condition_a:
       # do something
       break
   ...
   if condition_b:
       # do something
       break
   # more code here
   break

You can emulate goto's functionality with exceptions:

try:
    # blah, blah ...
    # raise MyFunkyException as soon as you want out
except MyFunkyException:
    pass

Disclaimer: I only mean to bring to your attention the possibility of doing things this way, while in no way do I endorse it as reasonable under normal circumstances. As I mentioned in a comment on the question, structuring code so as to avoid Byzantine conditionals in the first place is preferable by far. :-)
