# # PRACTICE QUESTIONS

# #1. WAP to ask a user to enter names of their 3 favorite movies & store them in a list.

# movies = []
# mov1 = input("Enter your 1st Movie: ")
# mov2 = input("Enter your 2nd Movie: ")
# mov3 = input("Enter your 3rd Movie: ")
# movies.append(mov1)
# movies.append(mov2)
# movies.append(mov3)
# print("Your favorite movies are: ", movies)

# movies = []
# movies.append(input("Enter your first movie: "))
# movies.append(input("enter your second movie: "))
# movies.append(input("Enter your third movie: "))
# print("Your favorite movies are: ", movies)


# # 2. WAP to check if a list contains a palindrome of elements. (Hint: use copy() method)

# list1 = [1, 2, 1, 2, 1]

# copy_list1 = list1.copy()
# copy_list1.reverse()
# if(copy_list1 == list1):
#     print(list1, "Palindrome")
# else:
#     print(list1, "Not a Palindrome")


# # 3. WAP to count the number of students with the "A" grade in the following tuple.

# grade = ("A", "D", "C", "A", "B", "A")
# print(grade.count("A"))


# # 4. WAP to store the values in a list & sort them from "A" to "D".

# grade = ["A", "D", "C", "A", "B", "A"]
# grade.sort()
# print(grade)
