how often does a word occur in this column?

Great answer @Lars60+. I thnk the newlines should be replaced by vertical bars before parsing (see 'Adventure\n' in line one).

from collections import Counter

data = 'Genres\nAction|Adventure\nAction|Adventure|Animation\nAction|Adventure|Animation|Comedy|Drama\n' \
    'Action|Adventure|Animation|Comedy|Family\nAction|Adventure|Animation|Drama|Family\n' \
    'Action|Adventure|Animation|Family\nAction|Adventure|Animation|Family|Fantasy\n' \
    'Action|Adventure|Animation|Family|Mystery\nAction|Adventure|Animation|Family|Science Fiction\n' \
    'Action|Adventure|Animation|Fantasy\nAction|Adventure|Animation|Fantasy|Horror\n' \
    'Action|Adventure|Animation|Fantasy|Science Fiction\n'
    
data_list = data.replace('\n', '|')
data_list = data_list.strip().split('|')
print(Counter(data_list).most_common(1))

Output:
[('Action', 12)]
