Question

I have this function. My pygame’s text to rectangle converter.

def text_to_rect(text, name='default'):
    try:
        font  = load.text_style[name]['font']
        aa    = load.text_style[name]['aa']
        color = load.text_style[name]['color']
    except NameError:
        font_path = pygame.font.get_default_font()
        font = pygame.font.Font(font_path, 24)
        aa = 1
        color = (0,0,0)
        if not name=='default':
            text = text+'(ERROR: Global load object not defined.)'
    except KeyError:
        font_path = pygame.font.get_default_font()
        font = pygame.font.Font(font_path, 24)
        aa = 1
        color = (0,0,0)
        if not name=='default':
            text = text+'(ERROR: '+name+' text style does not exist.)'
    return font.render(text,aa,color)

In two except blocks there are 4 lines of the same code. I want to run these 4 lines if any exception occurs, then rest to a specific exception.

Answer 1

You can actually combine exceptions into one statement:

try:
    #code that you expect errors from

except KeyError, NameError:
    #exception code

except:
    #Of course, you can also do a naked except to catch all
    #exceptions,
    #But if you're forced to do this, you're probably
    #doing something wrong. This is bad coding style.

EDIT
For your case, if you want your code execution to depend on the error caught, do this:

try:
    #Code to try
except (KeyError, NameError) as e:
    #Code to execute in either case
    if isinstance(e, KeyError):
        #code to execute if error is KeyError
    else:
        #code to execute if error is NameError
