Answer 1

data.items() will work in both python2 and python3 as well. You can see the script below which wrote in python2.

>>> for k,v in data.items():
...     df = pandas.DataFrame(v.split('-'))
...     df.to_csv(k + '.csv')
...
>>> import os
>>> [ i for i in os.listdir('.') if i.endswith('.csv')]
['a.csv', 'b.csv', 'c.csv', 'd.csv']
