Road Map
• The Internet (2-3 weeks)
– Layered architecture
– Applications: web, email, p2p,
etc.
– The path of your
email/webpage.

Road Map
• Python Programming
(3-4 weeks)
– Getting started (Chapter
1)
– Basic concepts: type,
variable, I/O (Chapter 2)
– Loops: while, for, if
(Chapters 3-4)

Why Programming
• What is a program?
• You can handle little problems yourself
• You know when you hire someone how big
a job it is (like going to a mechanic)
• You have some idea of what is possible.
• A good programmer has more job options
(you’ll need more than this one class,
though)

Why Python?
•
•
•
•
•
ECS15
Great for interfacing one program to another
Free!
Used in industry –Google, ILM, NASA….
Easy to get started with!
Lots of “libraries” (add-ons) that do things
like sound editing, computational biology,
Web database access…..

What should you get from this class?
• You can handle little problems yourself
– Do research, find interesting stuff
– Security
– impress your friends
• Your know when you hire someone how big a job
is.
• You know some idea of what is possible
• People with good IT skills have more job options.

It teaches you to think!
• The computer is your genie in a bottle
– It can be your best help
– It can be really frustration
•

ECS15
It does exactly what you tell it to
Your job is to figure out what/how to tell it.
Learning the language is easy, …
Some people really like it!

Other options
• ECS 10: Programming in Python
– You will get full credit (after taking ECS 15)
– GE class
• ECS 30: More intensive class for those with
some programming experience (basic, c,
java), learn C++, required for ECS majors.
