How to make Python First Programme

                First programme in Python

In My views Python is simplest language to enter in the Programming World.
It has very simple Syntax ,there is no semicolon and brackets are Required.

And also you should have to remember that Python is fully "Object Oriented" and a strong and Powerful language . In Linux python is already installed and
Window users see here to see how to install and compile.

now lets started with its First Programme .

Type Python on terminal(for linux users)

root@bt:~#python
print "Hello kushagra"

Hello kushagra
2+8
10
a=2
b=8
c=a+b
print c
10

Eh! Easy naa :)

Now we should start by writing scripts in Python .

open any text Editor and just write

print "Hello Kushagra"

and save it as Hello.py on Desktop
now open your terminal by cd command go to your Desktop

output:
root@bt:~#cd Desktop
root@bt:~/Desktop# python Hello.py
Hello Kushagra
root@bt:~/Desktop#
Happy programming .

How to implement If condition in python

                                                  If Statement

If condition is used to decision making ,so if statement is also know selection statement

Syntax:

if  condition :
  Statement ;
else:
  Statement;

Programme:

a=20

print('enter any numb')

x=int(input())

    print('oops guess larger number')

elif x>a:

    print('oops guess smaller number dude')

else :

Output:

5
