Python Exercise: Lists, Sets, and Tuples (Beginner Friendly)

List Exercises:

1. Create and Access List

   • Create a list called fruits containing "apple", "banana", "cherry", and "date".

   • Print the second item in the list.

   • Change the third item to "blueberry" and print the updated list.

2. List Operations

   • Given the list numbers = [1, 2, 3, 4, 5]:

     • Add the number 6 to the end of the list

     • Insert the number 0 at the beginning of the list

     • Remove the number 3 from the list

     • Print the final list

3. List Slicing

   • Given letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g']:

     • Create a new list containing elements from index 2 to 5

     • Create another list containing every alternate element starting from index 0

     • Print both new lists

4. List Methods

   • Create a list colors = ["red", "green", "blue"]

   • Use list methods to:

     • Add "yellow" to the list

     • Remove "green" from the list

     • Reverse the order of the list

     • Print the final list

5. List Length and Checking

   • Create a list pets = ["dog", "cat", "fish", "bird"]

   • Print the number of items in the list

   • Check if "hamster" is in the list and print the result

   • Check if "cat" is in the list and print the result

Set Exercises:

1. Create and Access Set

   • Create a set called animals containing "dog", "cat", "rabbit", and "hamster".

   • Add "parrot" to the set.

   • Remove "rabbit" from the set.

   • Print the final set.

2. Set Operations

   • Given two sets:

       set1 = {1, 2, 3, 4, 5}
       set2 = {4, 5, 6, 7, 8}
     

     • Find and print the union of both sets

     • Find and print the intersection of both sets

     • Find and print the difference between set1 and set2

3. Set Methods

   • Create a set prime_numbers = {2, 3, 5, 7}

   • Use set methods to:

     • Add 11 to the set

     • Remove 3 from the set

     • Check if 5 is in the set

     • Print the final set and the result of the membership check

4. Frozen Set

   • Create a regular set colors = {"red", "green", "blue"}

   • Convert it to a frozen set

   • Try to add "yellow" to the frozen set (catch the error if it occurs)

   • Print the frozen set

5. Set Length and Clearing

   • Create a set vowels = {'a', 'e', 'i', 'o', 'u'}

   • Print the number of elements in the set

   • Clear all elements from the set

   • Print the empty set

Tuple Exercises:

1. Create and Access Tuple

   • Create a tuple called days containing "Monday", "Tuesday", "Wednesday", "Thursday", "Friday".

   • Print the third item in the tuple.

   • Try to change the second item to "Sunnyday" (note what happens)

2. Tuple Unpacking

   • Create a tuple student = ("John Doe", 25, "Computer Science")

   • Unpack the tuple into three variables: name, age, and major

   • Print each variable separately

3. Tuple Concatenation

   • Given two tuples:

       tuple1 = (1, 2, 3)
       tuple2 = (4, 5, 6)
     

     • Create a new tuple that combines both tuples

     • Create another tuple that repeats tuple1 three times

     • Print both new tuples

4. Tuple Methods

   • Create a tuple numbers = (5, 2, 8, 2, 7, 2, 9, 2)

   • Use tuple methods to:

     • Count how many times 2 appears in the tuple

     • Find the index of the first occurrence of 7

     • Print both results

5. Tuple Conversion

   • Create a list cities = ["Paris", "London", "Tokyo"]

   • Convert the list to a tuple

   • Try to append "New York" to the tuple (note what happens)

   • Print the tuple

List Answers:

1.  fruits = ["apple", "banana", "cherry", "date"]
    print(fruits[1])  # banana
    fruits[2] = "blueberry"
    print(fruits)  # ['apple', 'banana', 'blueberry', 'date']
   

2.  numbers = [1, 2, 3, 4, 5]
    numbers.append(6)
    numbers.insert(0, 0)
    numbers.remove(3)
    print(numbers)  # [0, 1, 2, 4, 5, 6]
   

3.  letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
    slice1 = letters[2:6]  # ['c', 'd', 'e', 'f']
    slice2 = letters[::2]  # ['a', 'c', 'e', 'g']
    print(slice1, slice2)
   

4.  colors = ["red", "green", "blue"]
    colors.append("yellow")
    colors.remove("green")
    colors.reverse()
    print(colors)  # ['blue', 'red', 'yellow']
   

5.  pets = ["dog", "cat", "fish", "bird"]
    print(len(pets))  # 4
    print("hamster" in pets)  # False
    print("cat" in pets)  # True
   

Set Answers:

1.  animals = {"dog", "cat", "rabbit", "hamster"}
    animals.add("parrot")
    animals.remove("rabbit")
    print(animals)  # {'dog', 'cat', 'hamster', 'parrot'}
   

2.  set1 = {1, 2, 3, 4, 5}

4.  colors = {"red", "green", "blue"}
    frozen_colors = frozenset(colors)
    try:
        frozen_colors.add("yellow")  # This will raise an AttributeError
    except AttributeError:
        print("Cannot modify a frozen set")
    print(frozen_colors)  # frozenset({'red', 'green', 'blue'})
   

5.  vowels = {'a', 'e', 'i', 'o', 'u'}
    print(len(vowels))  # 5
    vowels.clear()

Tuple Answers:

1.  days = ("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
    print(days[2])  # Wednesday
    # days[1] = "Sunnyday"  # This will raise a TypeError
   

2.  student = ("John Doe", 25, "Computer Science")
    name, age, major = student
    print(name)  # John Doe
    print(age)  # 25
    print(major)  # Computer Science
   

3.  tuple1 = (1, 2, 3)
    tuple2 = (4, 5, 6)
    combined = tuple1 + tuple2  # (1, 2, 3, 4, 5, 6)
    repeated = tuple1 * 3  # (1, 2, 3, 1, 2, 3, 1, 2, 3)
    print(combined, repeated)
   

4.  numbers = (5, 2, 8, 2, 7, 2, 9, 2)
