The "Hello, World!" program in Python serves as the quintessential starting point for beginners embarking on their programming journey. It epitomizes the simplicity and elegance of Python's syntax while introducing the fundamental concept of outputting text to the console. With just a single line of code, "print('Hello, World!')", Python novices witness the immediate gratification of seeing their message displayed on the screen. This straightforward program not only demonstrates the ease of Python's syntax but also lays the groundwork for understanding key concepts such as functions, strings, and basic program execution. Beyond its technical significance, the "Hello, World!" program symbolises the initiation into the vast world of programming, inspiring curiosity and igniting a passion for exploration and learning.

print("hello world")

2. Addition of Two Numbers

In Python, adding two numbers is a straightforward and intuitive process. Utilizing the simple syntax of the language, one can easily perform this basic arithmetic operation. By assigning the numbers to variables and using the addition operator (+), Python seamlessly computes the sum. Whether the numbers are integers, floating-point numbers, or even complex numbers, Python's dynamic typing system handles the addition effortlessly. Additionally, Python's readability enhances comprehension, making the code accessible to both beginners and experienced developers alike. This fundamental operation serves as a foundational building block in Python programming, showcasing the language's elegance and efficiency in performing everyday tasks.

num1 = 5

num2 = 3

sum = num1 + num2

print("The sum of ", num1, " and ", num2, " is ", sum)

3. Check Even or Odd

In Python, determining whether a number is even or odd is a fundamental task that illustrates the language's simplicity and efficiency. With just a few lines of code, one can quickly write a program to check this condition. By utilizing the modulo operator (%), Python effortlessly determines the remainder when dividing the given number by 2. If the remainder is zero, the number is even; otherwise, it is odd. This straightforward process showcases Python's readability and ease of use, making it an ideal choice for beginners learning programming concepts. Moreover, this basic program serves as a building block for more complex logic and algorithms, highlighting Python's versatility across various domains of application development, data analysis, and scientific computing.

num = int (input (“Enter any number to test whether it is odd or even: “)

if (num % 2) == 0:

              print (“The number is even”)

else:

              print (“The provided number is odd”)

Output:

Enter any number to test whether it is odd or even:

887

887 is odd.

4. Simple Calculator

A simple calculator program in Python can be designed using basic arithmetic operations such as addition, subtraction, multiplication, and division. Utilizing Python's built-in functions and control structures, one can prompt the user to input two numbers and select the desired operation. Subsequently, the program performs the operation and displays the result. For instance, one can define functions for addition, subtraction, multiplication, and division, then prompt the user to choose an operation. Based on the user's choice, the corresponding function is called with the provided numbers as parameters, and the result is printed. Additionally, error handling can be implemented to handle cases like division by zero or invalid inputs. Overall, with just a few lines of code, a simple yet functional calculator can be created in Python.

# This function adds two numbers

def add(x, y):

    return x + y

# This function subtracts two numbers

def subtract(x, y):

    return x - y

# This function multiplies two numbers

def multiply(x, y):

    return x * y

# This function divides two numbers

def divide(x, y):

    return x / y

print("Select operation.")

print("1.Add")

print("2.Subtract")

print("3.Multiply")

print("4.Divide")

while True:

    # take input from the user

    choice = input("Enter choice(1/2/3/4): ")

    # check if choice is one of the four options

    if choice in ('1', '2', '3', '4'):

        try:

            num1 = float(input("Enter first number: "))

            num2 = float(input("Enter second number: "))

        except ValueError:

            print("Invalid input. Please enter a number.")

            continue

        if choice == '1':

            print(num1, "+", num2, "=", add(num1, num2))

        elif choice == '2':

            print(num1, "-", num2, "=", subtract(num1, num2))

        elif choice == '3':

            print(num1, "*", num2, "=", multiply(num1, num2))

        elif choice == '4':

            print(num1, "/", num2, "=", divide(num1, num2))

        # check if user wants another calculation

        # break the while loop if answer is no

        next_calculation = input("Let's do next calculation? (yes/no): ")

        if next_calculation == "no":

          break

    else:

        print("Invalid Input")

5. A leap year

A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. For example,

# Python program to check if year is a leap year or not

year = 2000

# To get year (integer input) from the user

# year = int(input("Enter a year: "))

# divided by 100 means century year (ending with 00)

# century year divided by 400 is leap year

if (year % 400 == 0) and (year % 100 == 0):

    print("{0} is a leap year".format(year))

# not divided by 100 means not a century year

# year divided by 4 is a leap year

elif (year % 4 ==0) and (year % 100 != 0):

    print("{0} is a leap year".format(year))

# if not divided by both 400 (century year) and 4 (not century year)

# year is not leap year

else:

    print("{0} is not a leap year".format(year))

In conclusion, writing basic Python programs like those to determine leap years or create calculators serves several important purposes. Firstly, it helps beginners grasp fundamental programming concepts such as variables, conditions, loops, and functions in a practical context. These programs offer a hands-on approach to learning syntax and logic, aiding in building a strong foundation for more complex projects. Additionally, they foster problem-solving skills by breaking down larger problems into smaller, manageable components. Understanding how to solve basic problems like calculating leap years or performing arithmetic operations lays the groundwork for tackling more advanced challenges in programming. Moreover, such programs encourage experimentation and creativity, as learners can modify and expand upon them to explore new functionalities and improve their coding abilities. Overall, writing basic Python programs is essential for novices to gain confidence, develop critical thinking skills, and pave the way for their journey towards becoming proficient programmers.
