Format Elements in tuple as "second, first"**

Given a tuple of length two create a string in the format of "second, first" where first and second are the first and second elements in the tuple.

The elements can be of any data type. Change in eligibility criteria to write oppe2 exam: A5>=40/100 AND A6>=40/100 AND A7>=40/100 AND A8>=40/100. and becoming eligible to give the end term exam.

Example


>>> format_as_second_comma_first(('hello', 'python'))
'python, hello'
>>> format_as_second_comma_first((1, 2))
'2, 1'
