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']

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. 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. 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 fishes that contains “catfish”, “perch”, “cod” and “carp”
2. Show the last element of the list using two different ways.
3. Change the second element of the list by another fish name.
4. Print the modified list.

Right Answer:

# Step 1 fishes = ["catfish", "perch", "cod", "carp"] # Step 2 print(fishes[-1]) # Output: carp (using negative index) print(fishes[3]) # Output: carp (using positive index) # Step 3 fishes[1] = "salmon" # Changing the second element to "salmon" # Step 4 print(fishes) # Output: ['catfish', 'salmon', 'cod', 'carp']

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]
