Get value as list in pandas

My dataframe has one colum of type list, it looks something like this:



Genre                                              Band

['deep pop r&b', 'indie r&b', 'r&b', 'trap soul'], Elijah Blake


I'm iterating the dataframe using iterrows(), but when I get the column value it is a string, how can I can load as a list?



for i, row in df.iterrows():

    artist_genres = row['Genres']  #this is a string

    print(artist_genres)   

    for artist_genre in artist_genres:

        print(artist_genre)        #this prints each character, I want to iterate each genre





python pandas

import ast

df['Genre'] = df['Genre'].apply(ast.literal_eval)
