   3. Print the first character of the first string in the first item of list1 with a suitable message (HINT: The first item is the item with index 0).
   4. Print the sum of the last 4 numbers in the last element of list1, with a suitable message.
   5. Append the list ['apple', 'pear', 'grape'] to list1 and print the updated value of list1 with a suitable messag
   6. Save your code to a file with name lab4sol.py.
   7. Submit your Python code (i.e. lab4sol.py file) through BB.

Answer 1

list1 = [['Rose', 'Daisy'], 7, 0, 5.5, [1, 22, 2.45, 3, 6, 5.8]]

# printing the list

print (list1)

# printing the length of list by using len() funtion

print("number of items in list1 is:",len(list1))

#printing first char the first element of first list

print("The first item is the item with index 0 :",list1[0][0][0])

#printing the sum of last four elements in the list

print("The sum of the last four elements in the list1 :",list1[4][2]+list1[4][3]+list1[4][4]+list1[4][5])

# appending the list to list1

list1.append(['apple', 'pear', 'grape'])

print("final list1 after appending the list: ",list1)
