list1 = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
list2 = [28.5, 30.1, 33.4, 35.4, 36.6, 35.8, 35.2, 36.3, 35.5, 33.8, 30.7, 27.6]
combinedlist = zip(list1, list2)
print("Minimun Value is - " + str(min(list2)))
average = sum(list2) / len(list2)
print("Average Value is - " + str(round(average, 2)))
for index, key in combinedlist:
if key == min(list2):
print(index, key)
Will Give
