Simple Program Code In Python  ( Python For Beginners) Part - 2

1. Check for Palindrome:

def is_palindrome(s):

return s == s[::-1]

string = input("Enter a string: ")

if is_palindrome(string):

print("Palindrome")

else:

print("Not a palindrome")

2. Find the Largest Among Three Numbers:

a = float(input("Enter the first number: "))

b = float(input("Enter the second number: "))

c = float(input("Enter the third number: "))

max_num = max(a, b, c)

print("Largest number:", max_num)

3. Print Multiplication Table:

num = int(input("Enter a number: "))

for i in range(1, 11):

print(f"{num} x {i} = {num * i}")

4. Convert Celsius to Fahrenheit:

celsius = float(input("Enter temperature in Celsius: "))

fahrenheit = (celsius * 9/5) + 32

print("Temperature in Fahrenheit:", fahrenheit)

5. Simple String Operations:

string = "Hello, World!"

print("Length of the string:", len(string))

print("Uppercase:", string.upper())

print("Lowercase:", string.lower())

print("Reversed string:", string[::-1])

6. Bubble Sort Algorithm:

def bubble_sort(arr):

n = len(arr)

for i in range(n - 1):

for j in range(0, n - i - 1):

if arr[j] > arr[j + 1]:

arr[j], arr[j + 1] = arr[j + 1], arr[j]

arr = [64, 34, 25, 12, 22, 11, 90]

bubble_sort(arr)

print("Sorted array:", arr)

7. Check Leap Year:

def is_leap_year(year):

if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0):

return True

return False

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

if is_leap_year(year):

print("Leap year")

else:

print("Not a leap year")

8. Count Vowels in a String:

def count_vowels(s):

vowels = 'aeiouAEIOU'

count = 0

for char in s:

if char in vowels:

count += 1

return count

string = input("Enter a string: ")

print("Number of vowels:", count_vowels(string))

9. Find the LCM of Two Numbers:

def compute_lcm(x, y):

if x > y:

greater = x

else:

greater = y

while True:

if greater % x == 0 and greater % y == 0:

lcm = greater

break

greater += 1

return lcm

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

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

print("LCM:", compute_lcm(num1, num2))

10. Basic Class and Object:

class Rectangle:

def __init__(self, length, width):

self.length = length

self.width = width

def area(self):

return self.length * self.width

length = float(input("Enter length of the rectangle: "))

width = float(input("Enter width of the rectangle: "))

rect = Rectangle(length, width)

print("Area of the rectangle:", rect.area())
