Python simple program:

Print multiplication table of a number:
===========================
num = int(input("Enter the number: "))
print("Multiplication Table of", num)
for i in range(1, 11):
   print(num,"X",i,"=",num * i)

Print table of a number:
=================
num = int(input("Enter the number: "))
print("Multiplication Table of", num)
for i in range(1, 11):
   print(num * i)

Print sum of n natural number:
=======================
num = int(input("Enter the value of n: "))
hold = num
sum = 0
if num <= 0: 
   print("Enter a whole positive number!") 
else: 
   while num > 0:
        sum = sum + num
        num = num - 1;
   print("Sum of first", hold, "natural numbers is: ", sum)

Factorial of Number:
================
def factorial(num):
    """This is a recursive function that calls
   itself to find the factorial of given number"""
    if num == 1:
        return num
    else:
        return num * factorial(num - 1)
num = int(input("Enter a Number: "))
if num < 0:
    print("Factorial cannot be found for negative numbers")
elif num == 0:
    print("Factorial of 0 is 1")
else:
    print("Factorial of", num, "is: ", factorial(num))

Convert decimal to binary:
====================
def decimalToBinary(num):
   #This function converts decimal number to binary and prints it
    if num > 1:
        decimalToBinary(num // 2)
    print(num % 2, end='')
number = int(input("Enter any decimal number: "))
decimalToBinary(number)
