Python is an interpreted, high-level, general-purpose programming language. it is simple and easy to learn, powerful, high level and object oriented programming language. python syntax and dynamic typing with its interpreted nature makes it an ideal language for scripting and rapid application development.
python is easy to learn and powerful and versatile scripting language.it has a large and comprehensive standard library. python support multiple programming pattern, including object oriented, imperative and functional or procedural programming styles.
now a days python is a most demanding language in the world. python language code is very small and easy to understand. many application created by python language.

python basic programs
Q1)write a program in python to print hello world
-->
print('Hello world')
output - Hello world.
----------------------------------------------------
Q2)write a program in python to addtion of two number.
-->
num1 = 5
num2 = 6
sum = num1 + num2
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))
output - the sum of 5 and 6 is 11.
----------------------------------------------------------
Q3) write a program in python swipping of two number using third variable.
-->
x = 3
y = 6
# To take inputs from the user
#x = input('Enter value of x: ')
#y = input('Enter value of y: ')
z = x
x = y
y = z
print('The value of x after swapping: {}'.format(x))
print('The value of y after swapping: {}'.format(y))
output - The value of x after swapping: 6
The value of x after swapping: 3
-----------------------------------------------------------
Q4)write a program in python to find fatorial of a number.
--->
num = 5
# To take input from the user
#num = int(input("Enter a number: "))
factorial = 1
# check if the number is negative, positive or zero
if num < 0:
print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
else:
for i in range(1,num + 1):
factorial = factorial*i
print("The factorial of",num,"is",factorial)
output - The factorial of 5 is 120
-------------------------------------------------------------------------
Q5)Write a program in python to sum of given number.
-->
def getSum(n):
sum = 0
while (n != 0):
sum = sum + int(n % 10)
n = int(n/10)
return sum
n = 12
print(getSum(n))
output - 12
