You can use Counter if you want to do multiple count of the list

from collections import Counter
list = ['Jones','Adams','Frank','John','Lopez','Jones','Smith','Ivan','Julian','Carlos','Adams','Frank','Jones','John','Ivan']
print(Counter(list))

from collections import Counter

list = ['Jones','Adams','Frank','John','Lopez','Jones','Smith','Ivan','Julian','Carlos','Adams','Frank','Jones','John','Ivan']

print(Counter(list))

Result:

Counter({'Jones': 3, 'Adams': 2, 'Frank': 2, 'John': 2, 'Ivan': 2, 'Lopez': 1, 'Smith': 1, 'Julian': 1, 'Carlos': 1})

1 2	Counter({'Jones': 3, 'Adams': 2, 'Frank': 2, 'John': 2, 'Ivan': 2, 'Lopez': 1, 'Smith': 1, 'Julian': 1, 'Carlos': 1})
