Python is one of the most beginner-friendly programming languages, thanks to its simple syntax and powerful capabilities. If you're just starting out, practicing small code snippets is a great way to build your confidence.

Here are 10 beginner-friendly Python programs that cover fundamental concepts like variables, conditionals, functions, loops, and more. Let's dive in! 👇

---

1️⃣ Print "Hello, World!"

The classic first program in any language:

print("Hello, World!")

🧠 Concepts: Printing to the console.

---

2️⃣ Swap Two Variables (Without Using a Third Variable)

a = 5
b = 10

# Swapping without a third variable
a, b = b, a

print("a:", a, "b:", b)

🧠 Concepts: Tuple unpacking in Python.

---

3️⃣ Check if a Number is Even or Odd

num = 4
if num % 2 == 0:
    print(num, "is even")
else:
    print(num, "is odd")

🧠 Concepts: Conditionals and modulo operator.

---

4️⃣ Find the Largest of Three Numbers

a = 5
b = 10
c = 3

if a > b and a > c:
    print(a, "is the largest")
elif b > a and b > c:
    print(b, "is the largest")
else:
    print(c, "is the largest")

🧠 Concepts: Multiple conditions using if, elif, and else.

---

5️⃣ Calculate the Factorial of a Number

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

num = 5
print("Factorial of", num, "is", factorial(num))

🧠 Concepts: Recursion.

---

6️⃣ Check if a String is a Palindrome

def is_palindrome(s):
    return s == s[::-1]

s = "radar"
if is_palindrome(s):
    print(s, "is a palindrome")
else:
    print(s, "is not a palindrome")

🧠 Concepts: String slicing and comparison.

---

7️⃣ Reverse a String

def reverse_string(s):
    return s[::-1]

s = "hello"
print("Reverse of", s, "is", reverse_string(s))

🧠 Concepts: String slicing.

---

8️⃣ Find the Sum of Digits of a Number

def sum_of_digits(n):
    return sum(int(digit) for digit in str(n))

num = 12345
print("Sum of digits of", num, "is", sum_of_digits(num))

🧠 Concepts: String conversion, list comprehension.

---

9️⃣ Check if a Number is Prime

def is_prime(n):
    if n <= 1:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True

num = 29
if is_prime(num):
    print(num, "is a prime number")
else:
    print(num, "is not a prime number")

🧠 Concepts: Loops, conditionals, optimization with square root.

---

🔟 Generate Fibonacci Sequence up to N Terms

def fibonacci(n):
    fib_sequence = []
    a, b = 0, 1
    for _ in range(n):
        fib_sequence.append(a)
        a, b = b, a + b
    return fib_sequence

n = 10
print("Fibonacci sequence up to", n, "terms is", fibonacci(n))

🧠 Concepts: Loops, list operations, basic algorithm.
