    Status: Open => Answered

RaiMan proposed the following answer:
--- Could I setup the exception as a function?
no, not possible.

the proposal has the following restriction:

having this as suggested:

try:
    func1()
    func2()
    func3()
except ZeroDivisionError:
    print "ZeroDivisionError"
except FindFailed:
    type(Key.PRINTSCREEN)

will terminate after the first catched exeception and does not continue
with the next function call.

... but you can define your own guarded find:

def myFind(img, reg = None):
    try:
        if reg:
            m = reg.find(img)
        else:
            m = find(img)
    except:
            # here you can do your screenshot and write your log
            m = None
    return m

myFind(img1) # search on whole screen
myFind(img1, someRegion) # search in region

... but no need to do it with find:

def myFind(img, reg = None):
    if reg:
        m = reg.exists(img)
    else:
        m = exists(img)
    if not m:
        # here you can do your screenshot and write your log
    return m

same usage:
myFind(img1) # search on whole screen
myFind(img1, someRegion) # search in region
