What is an Array?

The array can store a list of elements of similar data type. Array can store more than one values under the same array name.

Access the Elements of an Array

Elements of array can be accessed by indexing them.

flower[0]= "Rose"
print(flower)

We should know about the fact that the indexing of an array starts from 0.

The Length of an Array

To determine the length of an array we use len(). To know more you can refer to this this.

flowers = ["Rose", "Jasmine", "Tulip"]
print(len(flower)) #returns 3

Adding Array Elements

We use the method append() to add an element to the array.

flowers = ["Rose", "Jasmine", "Tulip"]
flower.append("Sunflower")
print(flowers) #returns ['Rose', 'Jasmine', 'Tulip', 'Sunflower']

Removing Array Elements

In order to remove an element from the array, we use pop() and remove() methods.

flowers = ["Rose", "Jasmine", "Tulip"]
flowers.remove("Jasmine")
print(flowers) #returns['Rose', 'Tulip']

In the pop() method we only need the index of the element that should be removed.

flowers = ["Rose", "Jasmine", "Tulip"]
flowers.pop(1)
print(flowers) #returns['Rose', 'Tulip']

Loop in Array

We can use for loop in to introduce loop in array

flowers = ["Rose", "Jasmine", "Tulip"]
for x in flowers:
  print(flowers)

Array Methods

There are built-in methods in array :

• append()
• count()
• copy()
• extend()
• clear()
• pop()
• remove()
• reverse()
• sort()
• index()
• insert()
