How to cast string back into a list

Question

I have a list:

ab = [1, 2, a, b, c]

I did:

strab = str(ab).

So strab is now a string.

In the context of setting a numpy array element with a sequence, you can use the built-in join to bypass setting it to a string:

str_list_obj = '-'.join(list_obj)

and afterwards when needed split the string sequence again with the same connector (provided it does not appear in the list's strings):

og_list_obj = str_list_obj.split("-")
