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. 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. 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. 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 mylist that contains ‘abc’, False, 1 and 3.14159.
2. Change False and 1 to True and 0 in one operation.
3. Extract the element ‘abc’ from the list and assign it to a variable in one operation.
4. Print that variable.
5. Assign the 3 list elements into 3 variables in one operation.
6. Print these variables.

Right Answer:

# Step 1 mylist = ['abc', False, 1, 3.14159] # Step 2 mylist[1:3] = [True, 0] # Change False and 1 to True and 0 # Step 3 abc_var = mylist.pop(0) # Extract 'abc' and assign it to abc_var print(abc_var) # Output: 'abc' # Step 4 var1, var2, var3 = mylist # Assign the remaining list elements to variables # Step 5 print(var1, var2, var3) # Output: True, 0, 3.14159

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.")
