Simple Program Code In Python  ( Python For Beginners) Part-1

1. Hello World Program:

print("Hello, World!")

2. Simple Calculator:

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

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

print("Sum:", a + b)

print("Difference:", a - b)

print("Product:", a * b)

print("Quotient:", a / b)

3. Factorial of a Number:

def factorial(n):

if n == 0:

return 1

else:

return n * factorial(n - 1)

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

print("Factorial:", factorial(num))

4. Fibonacci Sequence:

def fibonacci(n):

if n <= 1:

return n

else:

return fibonacci(n - 1) + fibonacci(n - 2)

terms = int(input("Enter the number of terms: "))

print("Fibonacci sequence:")

for i in range(terms):

print(fibonacci(i))

5. Check for Prime Number:

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

if is_prime(num):

print("Prime")

else:

print("Not prime")

6. Simple Interest Calculator:

p = float(input("Enter the principal amount: "))

r = float(input("Enter the rate of interest: "))

t = float(input("Enter the time period: "))

interest = (p * r * t) / 100

print("Simple Interest:", interest)

7. Check for Even or Odd:

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

if num % 2 == 0:

print("Even")

else:

print("Odd")

8. Area of a Circle:

import math

radius = float(input("Enter the radius of the circle: "))

area = math.pi * radius * radius

print("Area:", area)

9. List Comprehension:

squares = [i ** 2 for i in range(10)]

print("Squares:", squares)

10. Simple File Handling:

# Writing to a file

with open("output.txt", "w") as file:

file.write("Hello, this is a sample text.")

# Reading from a file

with open("output.txt", "r") as file:

data = file.read()

print("Data from file:", data)
