Congratulations on your successful installation. Now you can start programming. Open Notepad++ and create a new file. In the new file, type the following:

print "Hello World!" 

Save the file as hello.py.

Open the command prompt and traverse to the folder where your file is located using cd and then the path of the folder. For executing the file, the command will be python hello.py as shown in the following screenshot:

It is quite easy, isn't it? Likewise, you can execute all the Python files. Once you start working on projects and large files, it's always good to remain organized by creating a folder structure.
