# Lists in Python

# Lists are used to store multiple items in a single variable.

# Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.

# Lists are created using square brackets:

mylist = ["apple", "banana", "cherry"]

# You access the list items by referring to the index number:

print(mylist[1]) # banana

# Change Item Value

# To change the value of a specific item, refer to the index number:

mylist = ["apple", "banana", "cherry"]

mylist[1] = "mango"

print(mylist) # ['apple', 'mango', 'cherry']

# Length of List

thislist = ["apple", "banana", "cherry"]

print(len(thislist)) # 3

# Add Items

# To add an item to the end of the list, use the append() method:

thislist = ["apple", "banana", "cherry"]

thislist.append("orange") # ['apple', 'banana', 'cherry', 'orange']

# To add an item at the specified index, use the insert() method:

thislist = ["apple", "banana", "cherry"]

thislist.insert(1, "orange") # ['apple', 'orange', 'banana', 'cherry']

# Remove Item

# There are several methods to remove items from a list:

# The remove() method removes the specified item:

thislist = ["apple", "banana", "cherry"]

thislist.remove("banana") # ['apple', 'cherry']

# The pop() method removes the specified index, (or the last item if index is not specified):

thislist = ["apple", "banana", "cherry"]

thislist.pop() # ['apple', 'banana']
