The following rhyme helps us remember how many days there are in any given month:
Thirty days has September, April, June, and November,
All the rest have thirty-one,
Except February which has twenty-eight.
More accurate versions of the rhyme deal with the problem posed by the leap year, but let's ignore that for now. Write a function called days which expects one argument, the name of a month as a string, and returns the number of days in that month as given in the rhyme. Assume the argument passed to the function is a valid argument; do not validate the argument. Here are some examples of how your function should work:
>>> days("January")
31
>>> days("February")
28
>>> days("March")
31
>>> days("April")
30
>>>
