【问题描述】:
#Creating empty list
movies = []
#Creating variable that will control number of DVD titles we can enter
dvds = 0
#Creating the while loop
while dvds < 1000000: #This ensures that a large amount of DVD titles can be entered depending on user's personal DVD collection
print ("Please enter a DVD from your personal collection- press the 'enter key' to stop adding movies")
next = input("> ")
#If conditional statement to verify input
if len(next) > 0 and next.isalpha():
movies.append(next)
dvds = dvds + 1 or dvds==''
else:
break
print (movies)
