Build the title and y-axis label

A plot shows one line per city in cities. Build the string you would hand to plt.title: 'Ave. Temperatures: ' followed by the city names separated by ', ', so it reads Ave. Temperatures: Boston, Phoenix, Minneapolis. Also build the y-axis label 'Degrees F' from unit, so it would read 'Degrees C' if unit were 'C'. You may find ', '.join(...) and an f-string useful. Assign the strings to title and ylabel.

cities = ['Boston', 'Phoenix', 'Minneapolis']
unit = 'F'
title = ...   # your code here
ylabel = ...  # your code here

cities = ['Boston', 'Phoenix', 'Minneapolis']
unit = 'F'
title = ...   # your code here
ylabel = ...  # your code here
