Answer 1

Use Series.str.join if there are lists:

cols = ['Place','Actor']
df1[cols] = df1[cols].apply(lambda x : x.str.join(', '))

EDIT: If there are strings use Series.str.strip and Series.str.replace:

cols = ['Place','Actor']
df1[cols] = df1[cols].apply(lambda x : x.str.strip('[]').str.replace("'","", regex=True))
