How can I convert C++ code to Python?

Can you show me how to convert a simple C++ program to Python?

Sure! What C++ program do you have in mind?

I have a program that calculates the factorial of a number.

Here's a simple C++ factorial program:

#include <iostream>
using namespace std;

int factorial(int n) {
    return (n == 1 || n == 0) ? 1 : factorial(n - 1) * n;
}

int main() {
    int num;
    cout << "Enter a number: ";
    cin >> num;
    cout << "Factorial: " << factorial(num);
    return 0;
}

In Python, it would look like this:

def factorial(n):
    return 1 if n in (0, 1) else n * factorial(n - 1)

num = int(input("Enter a number: "))
print("Factorial:", factorial(num))

That looks great! Can you explain how the recursion works in both languages?

Of course! In both C++ and Python, recursion works by a function calling itself. The base case stops the recursion when n is 0 or 1, returning 1. For other values, it multiplies n by the factorial of n-1, effectively breaking the problem down into smaller parts.
