1. Hello, World!
print 'Hello World!'
2. Addition of Two Numbers
num1 = int(input("Enter the first number: ")) num2 = int(input("Enter the second number: ")) sum = num1 + num2 print("The sum of", num1, "and", num2, "is", sum)
3. Multiplication on for loop
num = int(input("Enter a number: ")) for i in range(1, 11): print(num, "x", i, "=", num * i)
4. Finding the Largest of Three Numbers
num1 = int(input("Enter the first number: ")) num2 = int(input("Enter the second number: ")) num3 = int(input("Enter the third number: ")) if num1 >= num2 and num1 >= num3: print(num1, "is the largest number") elif num2 >= num1 and num2 >= num3: print(num2, "is the largest number") else: print(num3, "is the largest number")
5. Palindrome word Check
word = input("Enter a word: ") if word == word[::-1]: print(word, "is a palindrome") else: print(word, "is not a palindrome")
In conclusion, Python is a versatile, readable, and well-supported programming language that is ideal for a wide range of applications.
