Modifying Elements

# Python

aList = ['apple', 'banana', 'cherry']
aList[1] = 'kiwi'  # Change 'banana' to 'kiwi'
print(aList)  # Output: ['apple', 'kiwi', 'cherry']

%%js
// Javascript

let alist = ['apple', 'banana', 'cherry', 'grape'];

// Specify the index you want to update
let index = 2; // For example, to update 'cherry'

// Update the value at the specified index
alist[index] = 'kiwi'; // Now 'cherry' is replaced with 'kiwi'

console.log(alist); // Output: ['apple', 'banana', 'kiwi', 'grape']

Checking Length

# Python

aList = ['apple', 'banana', 'cherry']
number_of_elements = len(aList)  # Gets the number of elements
print(number_of_elements)  # Output: 3

%%js
// Javascript

let aList = ['apple', 'banana', 'cherry'];
let numberOfElements = aList.length; // Gets the number of elements
console.log(numberOfElements); // Output: 3

Interating through a List

# Python

for item in my_list:
{ <block of statement> }


%%js
// Javascript

let myList = ['apple', 'banana', 'cherry'];


for (let item of myList) {
   // Replace this comment with your block of statements
   console.log(item); // Example statement
}
