Exercise 0: The Setup

This chapter teach us how to setup your python development environment varied platforms.

My os is linux, python 2.7 and gedit are pre-installed and configured, so all i should do is just setup the preferences of gedit.

Python use whitespace indentation to delimit blocks, hence the first preference is whitespace, the following setup is stolen fromthe book:

1. Open Preferences select theEditor tab.
2. Change Tab width: to 4.
3. Select (make sure a check mark is in) Insertspaces instead of tabs.
4. Turn on "Automatic indentation" as well.

Additionally, we should also can see the line number, so Open the View tab turn on "Display line numbers".

Next, testing python and gedit.

Open the terminal, after type python, i get the python console, i can code and run it directly here.

Open another terminal, after type gedit, it will open the gui gedit, i can code directly here.
