how to edit strings in a list (PYTHON) : i am not so familiar with python, and i don't know how to do this..  So I have a list that looks like this:

    animal_id = ['id01', 'id02', 'id03', 'id04', 'id05']

and I would like to make a new list from the list above, using string manipulation. and the new list should look like this:

    animal_list = ['a01', 'a02', 'a03', 'a04', 'a05']

i think i would have to make a for loop, but i dont know what methods (in string)  to use to achieve the desired output
