# (Solved) : Using Python 37 Exercise 1 Comparing Song Lengths Inside Assignment9py Complete Function D Q42750597 . . .

USING PYTHON 3.7:

Exercise 1 – Comparing song lengths

Inside assignment9.py, complete the function design for theis_longer function, which takes two songs as parameters, andreturns the longer of the two songs. In the case of a tie, the songthat is the first parameter is returned.

Exercise 2 – Counting the number of songs with a givenartist

Inside assignment9.py, complete the function design for thecount_with_artist function, which takes a list of songs and astring (representing the name of an artist) as parameters, andreturns the number of songs in the list with the given artist.
