1. Create a list named floats that contains 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7 and 8.8
2. Use slicing to get the elements 2.2, 3.3 and 4.4 in one operation.
3. Use slicing to get the elements from 3.3 to the end of the list.
4. Use slicing to get the elements from the start of the list to 5.5 included.
5. Use slicing to reverse the list.

Right Answer:

# Step 1 floats = [1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8] # Step 2 print(floats[1:4]) # Output: [2.2, 3.3, 4.4] # Step 3 print(floats[2:]) # Output: [3.3, 4.4, 5.5, 6.6, 7.7, 8.8] # Step 4 print(floats[:5]) # Output: [1.1, 2.2, 3.3, 4.4, 5.5] # Step 5 print(floats[::-1]) # Output: [8.8, 7.7, 6.6, 5.5, 4.4, 3.3, 2.2, 1.1]

1. Create a list named integers that contains 0, 1 and 3.
2. Add the number 4 to the end of the list using two different methods.
3. Add the number 2 in the list at the correct index to get a sequence.
4. Print the list, it should display 0, 1, 2, 3, 4.
5. Create a new list that contains 5, 6, 7 and 8.
6. Add this new list at the end of the integers list.
7. Remove the number 0 from the list.

Right Answer:

# Step 1 integers = [0, 1, 3] # Step 2 integers.append(4) # Method 1: Using append() integers += [4] # Method 2: Using += operator # Step 3 integers.insert(2, 2) # Insert 2 at the correct index to create a sequence # Step 4 print(integers) # Output: [0, 1, 2, 3, 4] # Step 5 new_list = [5, 6, 7, 8] # Step 6 integers.extend(new_list) # Adding the new list at the end of the integers list # Step 7 integers.remove(0) # Removing the number 0 from the list print(integers) # Output: [1, 2, 3, 4, 5, 6, 7, 8]

1. Create a list named matrix that contains:
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
2. Print the element 8.
3. Print the second row of the matrix, i.e. 4, 5 and 6.
4. Print the third column of the matrix, i.e. 3, 6 and 9.
5. Print the diagonal of the matrix, i.e., 1, 5 and 9.

Right Answer:

# Step 1 matrix = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ] # Step 2 print(matrix[2][1]) # Output: 8 # Step 3 print(matrix[1]) # Output: [4, 5, 6] # Step 4 third_column = [row[2] for row in matrix] print(third_column) # Output: [3, 6, 9] # Step 5 diagonal = [matrix[i][i] for i in range(len(matrix))] print(diagonal) # Output: [1, 5, 9]

1. Create a list named fruits containing the following items: "apple", "banana", "cherry".
2. Print the list to ensure it has been created correctly.
3. Create a tuple named vegetables containing the items: "carrot", "broccoli", "lettuce".
4. Print the tuple.

Right Answer:

# Step 1 fruits = ["apple", "banana", "cherry"] # Step 2 print(fruits) # Output: ['apple', 'banana', 'cherry'] # Step 3 vegetables = ("carrot", "broccoli", "lettuce") # Step 4 print(vegetables) # Output: ('carrot', 'broccoli', 'lettuce')

1. Given a tuple named months that contains "Jan", "Feb", "Mach” and "Apr"
2. Try to correct the typo in "Mach" to "March".
3. What happens?
4. Convert the tuple into a list.
5. Retry to correct the typo in "Mach" to "March".
6. Convert the list into a tuple.
7. Print the tuple.

Right Answer:

# Step 1 months = ("Jan", "Feb", "Mach", "Apr") # Step 2 # Trying to correct the typo will raise an error as tuples are immutable. # Step 3 - Explanation # Tuples are immutable, meaning we cannot change their items directly. # Step 4 months_list = list(months) # Converting tuple to list # Step 5 months_list[2] = "March" # Correcting the typo # Step 6 months = tuple(months_list) # Converting the list back to a tuple # Step 7 print(months) # Output: ('Jan', 'Feb', 'March', 'Apr')

1. Given a list named colors that contains "red", "blue", "green", "yellow" and "pink"
2. Print the second and fourth items from the list.
3. Given the tuple named grades that contains "A", "B", "C", "D" and "F"
4. Print the first and last items from the tuple.

Right Answer:

# Step 1 colors = ["red", "blue", "green", "yellow", "pink"] # Step 2 print(colors[1]) # Output: blue print(colors[3]) # Output: yellow # Step 3 grades = ("A", "B", "C", "D", "F") # Step 4 print(grades[0]) # Output: A print(grades[-1]) # Output: F

1. Create a list named sports that contains "Football", "Basketball", "Swimming" and
"Tennis".
2. Ask the user for their favorite sport.
3. Print "We love that too!" if the user's favorite sport is in the list.

Right Answer:

# Step 1 sports = ["Football", "Basketball", "Swimming", "Tennis"] # Step 2 favorite_sport = input("Enter your favorite sport: ") # Step 3 if favorite_sport in sports: print("We love that too!") else: print("That's a great sport, but not on our list.")

1. Ask the user to provide three numerical inputs.
2. Create a tuple out of them.
3. If the sum of the first and second elements of the tuple is greater than the third, print
the tuple in reverse.
4. Otherwise, print the tuple normally.

Right Answer:

# Step 1 num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) num3 = float(input("Enter third number: ")) # Step 2 num_tuple = (num1, num2, num3) # Step 3 and Step 4 if num1 + num2 > num3: print(num_tuple[::-1]) # Print the tuple in reverse else: print(num_tuple) # Print the tuple normally

1. Given a list named animals that contains "cat", "dog" and “apple”
2. Remove the “apple” from the list.
3. Print the list.
4. Add "rabbit" to the list.
5. Print the list.

Right Answer:

# Step 1 animals = ["cat", "dog", "apple"] # Step 2 animals.remove("apple") # Removing "apple" from the list # Step 3 print(animals) # Output: ['cat', 'dog'] # Step 4 animals.append("rabbit") # Adding "rabbit" to the list # Step 5 print(animals) # Output: ['cat', 'dog', 'rabbit']

1. Given a list named days that contains "Monday", "Tuesday", "Wendesday",
"Thursday" and "Friday".
2. Correct the typo in "Wendesday" to "Wednesday" using the days list.
3. Print the list to ensure the change has been made.

Right Answer:

# Step 1 days = ["Monday", "Tuesday", "Wendesday", "Thursday", "Friday"] # Step 2 days[2] = "Wednesday" # Correcting the typo # Step 3 print(days) # Output: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']
