Multiple try codes in one block

Question

I have a problem with my code in the try block. To make it easy this is my code:

try:
    code a
    code b #if b fails, it should ignore, and go to c.
    c

Lets say each code is a function and its already written then the following can be used to iter through your coding list and exit the for-loop when a function is executed without error using the "break".

def a(): code a
def b(): code b
def c(): code c
def d(): code d

for func in [a, b, c, d]:  # change list order to change execution order.
   try:
       func()
       break
   except Exception as err:
       print (err)
       continue

I used "Exception " here so you can see any error printed. Turn-off the print if you know what to expect and you're not caring (e.g. in case the code returns two or three list items (i,j = msg.split('.')).
