Extract values from a column value containing a list of values

I have a column containing values that also contains a list of values. E.g,

actor = ["[Emil Eifrem,Hugo Weaving,Laurence Fishburne]"]
title = ["The Matrix"]

actors = pd.DataFrame(list(zip(actor, title)),
                      columns = ["actor", "title"])

The output that I am looking for is below,

actor = ["Emil Eifrem", "Hugo Weaving", "Laurence Fishburne"]
title = ["The Matrix"] * 3

actors = pd.DataFrame(list(zip(actor, title)),
                      columns = ["actor", "title"])

>Solution :

Your value in actor column is a string. You may use below to convert to a list first and then use explode.

actors.actor = actors.actor.str.strip('[]').str.split(',')
actors = actors.explode('actor', ignore_index=True)

print(actors):

                 actor       title
0          Emil Eifrem  The Matrix
1         Hugo Weaving  The Matrix
2   Laurence Fishburne  The Matrix
