Question

try: 
    os.execvp('sqlite3', args) 
except OSError, er: 
    if er.errno == 2: #file not found 
        raise OSError, _("sqlite3 executable not found. Is it installed?") 
    else: 
        raise 
except: 
    raise 

In the above code, the except statement catches the OSError but what does the er variable stand for?

EDIT: this one only excepts OSError; is there a way to except any error and get the exception object for it?

Answer 1

er is the actual exception object that got caught by the except clause.
