What Is a List?

A list is a collection of items in a particular order.

Initialize a list

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
birds = []

Accessing Elements in a List

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
print(bicycles[0])

Modify a value in the list

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
bicycles[0] = "tank"
print(bicycles[0])

Add a value in the list

# append a value
bicycles = ['trek', 'cannondale', 'redline', 'specialized']
bicycles.append("tank")

# insert a value in the beginning
bicycles = ['trek', 'cannondale', 'redline', 'specialized']
bicycles.insert(0, "tank")

Remove a value from a list

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
# please google and find thoe to remove element 'redline'

Finding the Length of a List

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
print(len(bicycles))

Iterate a List

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
for bicycle in bicycles:
    print(bicycle)

some additional method

bicycles = ['trek', 'cannondale', 'redline', 'specialized']
bicycles.sort()
print(bicycles)

bicycles.reverse()
print(bicycles)
