How to append 1 value to every tuple within a list?

```
 tuple_list = [('a','b'),('c','d'),('e','f')]
 value = 111

 Desired_List = [(111,'a','b'),(111,'c','d'),(111,'e','f')]

```

I've tried the following: 

```
   for x in tuple_list:
        x.append(111)

   for x in tuple_list:
        x + '111'

```

I prefer sublists over tuples, so is there anyway to change the tuples to sublists as well?

Notes: 
It actually doesn't matter whether the 111 is in the first index or the last index of the tuple.
