Start Writing Your Code

There are two ways to write code in Python

1. You can write your code in Python Interactive Mode. Open Command Prompt(Windows User) or Terminal(Linux or Mac users)  and type python and enter. It will open Python interactive mode. Here you can write code temporarily. You can check all the functionality of Python. However, If you want to save your code in system it is better to write code in script (see point 2)

2. You can Write your code in a Python Script. Open any text editor like notepad, notepad++(windows) or gedit(Linux) and create a new file and save it with .py extension(i.e. filename.py).

NOTE - It is advisable to use IDE(Integrated  Development Environment) i.e Sublime Text, pycharm.

Writing Python Code in Sublime Text

After installing Sublime Text in your system, open it and write your Python code. Save your  file with .py extension (i.e. filename.py). Go to Tools menu and go to build system and select Python. Now write your Python Code and run your python script with ctrl + B.
