Discussion on: What to Except When You're Excepting: Python error handling dos & don'ts

[Duy K. Bui]

So I will end up having nested try? As in

try:
    foo
except FooException:
    print "foo"
else:
    try:
        bar
    except BarException:
        print "bar"
    else:
        try:
            # ... so on so forth

?

potentially! but like i said, it might be worth refactoring those cases into separate functions

[Duy K. Bui]

So

def wrap_foo:
    try:
        foo
    catch FooException:
        print "foo"

def wrap_bar:
    # same as above

def main:
    wrap_foo
    wrap_bar

Am I getting there?

yeah, depending on what you're trying to do—if everything's decoupled and bar doesn't depend on the success of foo, then this approach is the way to go
