Popcorn Hack #2

Create a simple calculator in javascript and python

%%js
const prompt = require("prompt-sync")();

const firstNumber = parseFloat(prompt("Enter the first number: "));
const secondNumber = parseFloat(prompt("Enter the second number: "));
const operation = prompt("Enter the operation (+, -, *, /): ");

let result;

switch (operation) {
  case "+":
    result = firstNumber + secondNumber;
    break;
  case "-":
    result = firstNumber - secondNumber;
    break;
  case "*":
    result = firstNumber * secondNumber;
    break;
  case "/":
    if (secondNumber !== 0) {
      result = firstNumber / secondNumber;
    } else {
      result = "Error: Division by zero is not allowed.";
    }
    break;
  default:
    result = "Invalid operation!";
}

console.log("The result is:", result);

# Simple calculator in Python

first_number = float(input("Enter the first number: "))
second_number = float(input("Enter the second number: "))
operation = input("Enter the operation (+, -, *, /): ")

if operation == "+":
    result = first_number + second_number
elif operation == "-":
    result = first_number - second_number
elif operation == "*":
    result = first_number * second_number
elif operation == "/":
    if second_number != 0:
        result = first_number / second_number
    else:
        result = "Error: Division by zero is not allowed."
else:
    result = "Invalid operation!"

print("The result is:", result)


The result is: 4.0

Popcorn Hack 3

Write a function that takes a list of strings and an integer

%%js
function repeatStrings(strings, n) {
    return strings.map(str => str.repeat(n));
  }
  
  // Example usage:
  const strings = ["apple", "banana", "cherry"];
  const n = 3;
  console.log(repeatStrings(strings, n));
  // Output: ["appleappleapple", "bananabananabanana", "cherrycherrycherry"]
  

<IPython.core.display.Javascript object>

##Python
def repeat_strings(strings, n):
    return [s * n for s in strings]

# Example usage:
strings = ["apple", "banana", "cherry"]
n = 3
print(repeat_strings(strings, n))
# Output: ['appleappleapple', 'bananabananabanana', 'cherrycherrycherry']


['appleappleapple', 'bananabananabanana', 'cherrycherrycherry']

Popcorn Hack 4

a function that compares two sets, and checks if there is an value within set 2 that is within set 1. If a value from set 2 is in set 1, then return the boolean output ‘True’ . If not, then return the boolean value ‘False’.

%%js
function hasCommonValue(set1, set2) {
  return set2.some(value => set1.includes(value));
}

// Example usage:
const set1 = [1, 2, 3, 4, 5];
const set2 = [5, 6, 7];
console.log(hasCommonValue(set1, set2)); // Output: true

const set3 = [8, 9, 10];
console.log(hasCommonValue(set1, set3)); // Output: false


<IPython.core.display.Javascript object>

#Python

def has_common_value(set1, set2):
    return any(value in set1 for value in set2)

# Example usage:
set1 = {1, 2, 3, 4, 5}
set2 = {5, 6, 7}
print(has_common_value(set1, set2))  # Output: True

set3 = {8, 9, 10}
print(has_common_value(set1, set3))  # Output: False


True
False

Abstract keys of bananas, apples, and pears, and assign them to numbers 1, 2 and 3 in the most effective way

%%js
// Creating an object to map fruits to numbers
const fruitMap = {
  bananas: 1,
  apples: 2,
  pears: 3
};

// Accessing values through keys
console.log("Bananas:", fruitMap.bananas); // Output: Bananas: 1
console.log("Apples:", fruitMap.apples);   // Output: Apples: 2
console.log("Pears:", fruitMap.pears);     // Output: Pears: 3


<IPython.core.display.Javascript object>

#Python
# Creating a dictionary to map fruits to numbers
fruit_map = {
    "bananas": 1,
    "apples": 2,
    "pears": 3
}

# Accessing values through keys
print("Bananas:", fruit_map["bananas"])  # Output: Bananas: 1
print("Apples:", fruit_map["apples"])    # Output: Apples: 2
print("Pears:", fruit_map["pears"])      # Output: Pears: 3


Bananas: 1
Apples: 2
Pears: 3
