working with lists in python

FOLLOW THROUGH THIS BY TYPING THE CODE IN YOUR SCRIPT/INTERPRETER

# Printing a simple list
print("WORKING WITH LISTS AND MANIPULATING THEM n")
numbers = ["one", "two", "three"]
print("Original list:t {} n".format(numbers))

# Changing an element in a list
numbers[2] = "change three"
print("After changing numbers[3] the list became:t {} n".format(numbers))

# Adding elements to the end of a list
numbers.append("append four")
print("After appending 'four':t {} n".format(numbers))

# Inserting elements at specific positions in a list
numbers.insert(4, "insert five")
print("After inserting five:t {} ".format(numbers))

numbers.insert(0, "insert zero")
print("insert zero at the beginning:t {} n".format(numbers))

# Removing an item in a list 
del numbers[0]
print("Remove 'insert zero':t {} n".format(numbers))

# Using pop to remove the last element of a list and printing it
popped_item = numbers.pop()
print("The popped item is:t {} n".format(popped_item))
print("Popped the last item:t {}".format(numbers))

# Using pop(index) to remove an item from any position in the list
"""Passing a number in pop will remove the item in that index"""
pop_one = numbers.pop(0)
print("We have popped:t {}".format(pop_one))
print("After popping one:t {}n".format(numbers))

# Using remove() to remove a list item by value
numbers.remove("two")
print("After removing two:t {}".format(numbers))

--------
THE OUTPUT
WORKING WITH LISTS AND MANIPULATING THEM

Original list:   ['one', 'two', 'three']

After changing numbers[3] the list became:       ['one', 'two', 'change three']

After appending 'four':  ['one', 'two', 'change three', 'append four']

After inserting five:    ['one', 'two', 'change three', 'append four', 'insert five']
insert zero at the beginning:    ['insert zero', 'one', 'two', 'change three', 'append four', 'insert five']

Remove 'insert zero':    ['one', 'two', 'change three', 'append four', 'insert five']

The popped item is:      insert five

Popped the last item:    ['one', 'two', 'change three', 'append four']
We have popped:  one
After popping one:       ['two', 'change three', 'append four']

After removing two:      ['change three', 'append four']
