Python Programming Basics With Ubuntu Linux

In the terminal you can run your python programs:
Go To Applications->Accessories->Terminal

python yourprogramhere.py

Note you need to be in the same directory as your python program, otherwise you need to type:

python /fulldirectorypath/yourprogramhere.py

or

python ./remainingdirectorypath/yourprogramhere.py

if you only type python at the prompt then you enter into the python program where it expects you to code in python commands at that point and time. Don't do this instead code your python programs in the text editor and run them with the python command.

Tip you can cycle through your previously typed commands in Linux by hitting the up and down arrows on the keyboard at the prompt.

Go To Applications->Accessories->Text Editor
in the Text Editor go to View->Highlight Mode->Scripts->Python
in the Text Editor go to Edit->Preferences
in Preferences make sure the following is checked:

in the View Tab
Text Wrapping All Options Checked
Display Line Numbers Checked
Highlight Current Line Checked
Display Right Margin Checked and leave it at 80
Highlight Matching Bracket Checked

in the Editor
Tab Width leave it at 8
Insert Spaces Instead of Tabs DO NOT CHECK!!!! This will keep your python programs from running correctly do to the fact that it relies on tabs for the begin and ending parts of code blocks such as functions, condition statements, etc.
Enable Automatic Indentation Checked.
File Saving Check All

in the Font & Color Tab
Use The System Fixed Width Font Do Not Check.
Now you can select a larger font which will make it easy to read your code and debug faster.

Now you are ready to code your program in Python in the text editor and save your file with the extension .py

After you save your file test the program in the terminal with your python command as explained up above. If you make a syntax error you will get detailed messages of what the problem is and what line the error is on. The error messages are better in the terminal than they are in Idle.

Getting Linux Distrobutions

Linux Distros:
Ubuntu
If you have an extra hard drive that you can put in your computer than this is a great distro of linux to learn on for the desktop. It is super easy to use and update.

Mandriva
Mandriva One for the linux that runs off of the CD that I am using in class.

Burning OS Images to a Disk on Windows for Free:
ImgBurn

Cheap Linux Distrobutions

If you can not get your linux disk to boot from your computer when it is in the CD/DVD drive after you have restarted the computer then you will need to go into your BIOS and setup the boot sequence to where the CD/DVD drive is before the hard drive in the boot sequence order.

1. CD/DVD
2. Hard Drive

Then save your BIOS configuration and exit the BIOS setup screen. Then restart your computer and your computer will boot off of the CD/DVD that has linux on it.
