Creating a list

# Python

# Creating an empty list
aList = []

# Creating a list with elements
aList = [1, 2, 3, 'apple', 'banana']

%%js
// Javascript

// Creating an empty array
let aList = [];

// Creating an array with elements
aList = [1, 2, 3, 'apple', 'banana'];

Accessing Elements

You can access an element at a specific index using the syntax aList[i]. Remember, the first element is at index 0.

# Python

aList = ['apple', 'banana', 'cherry']
print(aList[0])  # Output: 'apple'

%%js
// Javascript

const aList = ['apple', 'banana', 'cherry'];
const firstElement = aList[0]; // apple
const secondElement = aList[1]; // banana

Appending Elements

Use the append() method to add an element to the end of the list.

# Python

aList.append('grape')  # Adds 'grape' at the end
print(aList)  # Output: ['apple', 'banana', 'cherry', 'kiwi', 'grape']

%%js
// Javascript

let aList = ['apple', 'banana', 'cherry', 'kiwi'];

// Adding 'grape' at the end
aList.push('grape');

// Printing the array
console.log(aList); // Output: ['apple', 'banana', 'cherry', 'kiwi', 'grape']
