try except inside exec
by Michele Petrazzo June 1, 2009

Hi all, I want to execute a python code inside a string and so I use the exec statement. The strange thing is that the try/except couple don't catch the exception and so it return to the main code. Is there a solution to convert or make this code work? Thanks, Michele My code: STR = """ err = 0 try: def a_funct(): 1/0 except: import traceback err = traceback.format_exc() """ env = {} exec STR in env env["a_funct"]() print env["err"] My error: File "tmp/test_exec.py", line 14, in <module> env["a_funct"]() File "<string>", line 5, in a_funct ZeroDivisionError: integer division or modulo by zero

'render' is a function of one argument that returns a decorator. So, the equivalent is more like this: view = render('a')(render('b')(view)) or more simply: fb = render('b') view = fb(view) fa = render('a') view = fa(view) > Is there any way to know, in this case, that 'a' is the 'default' format? Will this do? (In case the formatting gets messed up, I've also posted the code to http://python.pastebin.com/f7f229d9d) ##from functools import wraps def render(c): def decorator(f): ## @wraps(f) def wrapper(*args, **kwds): if getattr(wrapper, 'outermost', False): print('outer wrapper', c) else: print('inner wrapper', c) return f(*args, **kwds) return wrapper return decorator def mark_as_top(f): print('marking', f) f.outermost = True ## @wraps(f) return f @mark_as_top @render('a') @render('b') @render('c') @render('d') def f(): pass f()

I resolved this problem with os.popen(). Thank you very much. By the way, a GreenHills project means a project built by GreenHills,:)
