HELP!

Question

I need help with this. Here are the instructions:

a The Downdog Yoga Studio offers five types of classes, as shown in Table 6-1. Design a program that accepts a number representing a class and then displays the name of the class.

b. Modify the Downdog Yoga Studio program so that numeric class requests can be entered continuously until a sentinel value is entered. Then display each class number, name, and a count of the number of requests for each class.

classNum = []
classesName = [
"Yoga 1", "Yoga 2", "Children's Yoga", "Prenatal Yoga", "Senior Yoga", "Quit"]
userInput = input
index = classesName.index
while index in classesName:
if userInput == "1":
userInput = input("Enter a class number or Quit: ")
print("Yoga 1")

elif userInput == "2":
print("Yoga 2")

elif userInput == "3":
print("Children's Yoga")

elif userInput == "4":
print("Prenatal Yoga")

elif userInput == "5":
print("Senior Yoga")

elif userInput == Quit:
break

print("Quit")

Answer 1

names = ["Yoga 1","Yoga 2","Children's Yoga","Prenatal Yoga","Senior Yoga"]
count = [0 for name in names]

print("\nDOWNDOG YOGA STUDIO\n\nlist of available class:")

for index, name in enumerate(names):
print(" %i: %s" % (index+1,name))

print()

while True:
try: index = int(input("Enter a class index, or 0 to quit: "))
except: index = -1
if not index: break
if index < 0 or len(names) < index:
print("Invalid value...")
continue
index -= 1
count[index] += 1
name = names[index]
print("Selected class name:",name)

print("\nCount summary of selected classes:")

for index, name in enumerate(names):
print(" %i: %s => %i" % (index+1,name,count[index]))

print()
