The problem of using the try exception dynamically

I have a function called transform_exceptions() that takes a list of functions, then calls each of the functions (functions are without arguments) and the exceptions that occur with the above convention to an object of ExceptionProxy and finally the list of transformed errors. It returns functions in the same order Note: If a function is executed without error, an ExceptionProxy object should be created and its msg value should be "ok!" Slow quantification

smple:

class ExceptionProxy(Exception):
    # define your class here

def transform_exceptions(func_ls):
    # implement your function here

def f():
    1/0

def g():
    pass

tr_ls = transform_exceptions([f, g])

for tr in tr_ls:
    print("msg: " + tr.msg + "\nfunction name: " + tr.function.__name__)

Output:

msg: division by zero
function name: f
msg: ok!
function name: g

my code :

from mimetypes import init


class ExceptionProxy(Exception):
    def __init__(self, msg, function):
        self.msg = msg
        self.function = function


def transform_exceptions(func_ls):
    exception_list = []
    for func in func_ls:
        try:
            func
        except Exception as e:
            r = ExceptionProxy(str(e), func)
            exception_list.append(r)
        else:
            r = ExceptionProxy("ok!", func)
            exception_list.append(r)

    return exception_list

You should do this when calling the function name in the list

func()

Also modified code:

class ExceptionProxy(Exception):
    def __init__(self,msg,function):
        self.msg = msg
        self.function = function


def transform_exceptions(func_ls):
    out = []
    for x in func_ls:
        try:
            x()
            a = ExceptionProxy("ok!", x)
        except Exception as e:
            a = ExceptionProxy(str(e), x)
        out.append(a)
    return out
