Connect the two list to a dictionary,then can use
max() with key parameter.>>> rainfall = [10, 20, 30]
>>> months = ['January', 'February', 'March']
>>> rainfall_record = dict(zip(months, rainfall))
>>> rainfall_record
{'January': 10, 'February': 20, 'March': 30}
>>>
>>> month, amount = max(rainfall_record.items(), key=lambda x:x[1])
>>> month
'March'
>>> amount
30
