Question

Provide Python code that does the following:

1. Create the following list in your program:

lst1 = ["apple", "banana", "pear", "grapefruit", "pineapple", "grape", "guava", "plum", "peach"]

Write code that then does the following:

1. Print the last item in the list.

2. Print the first item in the list.

3. Print all but the last three items in the list.

4. Print the first, third, fifth etc. items of the list.

5. Print the second, fourth, sixth etc. items of the list.

Parts A- E should work for a list with any number of elements. You can assume the list will have at least 6 elements.

**Please look at the Screenshot below and use this code to copy-paste.

***The code in the below screenshot is neatly indented for better understanding.


# Create the list
lst1 = ["apple", "banana", "pear", "grapefruit", "pineapple", "grape", "guava", "plum", "peach"]

# a. get last item by -1 index
print("The Last Item is: ", lst1[-1])

# b. first item as 0th index
print("the First Item is: ", lst1[0])

# c. all but last three is [0:-3]
print("All But Last Three are: ", lst1[0:-3])

# d. print odd indices using step 2 i.e., lst1[0::2]
print("The Odd Indices are: ", lst1[0::2])

# e. print the even indices using step 2 i.e, lst1[1::2] { start with index-1}
print("The Even Indices are: ", lst1[1::2])

OUTPUT:

The Last Item is: peach
the First Item is: apple
All But Last Three are: ['apple', 'banana', 'pear', 'grapefruit', 'pineapple', 'grape']
The Odd Indices are: ['apple', 'pear', 'pineapple', 'guava', 'peach']
The Even Indices are: ['banana', 'grapefruit', 'grape', 'plum']
