Turing provided an influential
formalization of the concept of
the algorithm and
computation with the Turing
machine.
Alan Turing,
(1912–1954)
"It is possible to invent a single machine which
can be used to compute any computable
sequence. "

Programming Languages
➲
➲
Java: is a cargo ship. It’s
very bulky. It’s very
enterprise~y. It can also
carry a lot of weight. Will
carry a project, but not very
fun to drive.
PHP: is a bamboo raft. A
series of hacks held together
by string. Still keeps afloat
though.
Languages
➲
C/C++: is a nuclear submarine. The
instructions are in 'Japanese', but all of the
hardware is optimized for performance.
Clumsy, in many aspects can be dangerous,
but it regularly goes where other boats go
when they have holes!
Languages
➲
Python: Small boat with outboard engine. Easy to
learn, fun to ride, no need to have a license, very
Dutch. Kids love it! Many use it as a hobby.
Even if you don't know what you are doing, can't
cause much damage

Python, a general purpose
programming language. It is
interpreted and dynamically
typed and is very suited for
interactive work and quick
prototyping,
while
being
powerful enough to write large
applications in Numpy, Scipy,
Matplotlib etc.

Python is now the most popular introductory teaching
language at Top U.S. Universities; MIT, Stanford
University, University of California, University of IIIinois,
Etc

understand Python)
-Easy to learn
-If you know Python, you can work with almost any
Python with little effort
-High-performance computing
-Powerful
-Python is broad
-Python is fast
-Python is free
-Python is efficient

How to go abut learning...
➲
First



➲
Then

➲
Ignore the details and focus on important principals!
Writing small programs is better than reading long
ones!
Find a few good on-line references and use them
often.
Take a fairly involved problem and write your own
program.
Later


If you are to write fairly long programs, details are
also important. Try to remember how, if not why.
Reading other people's well written code can help a
lot.
Python Language
Warnings do Matter
(not only errors)
➲
➲
A man is smoking a cigarette and blowing
smoke rings into the air. His girlfriend becomes
irritated with the smoke and says, "Can't you
see the warning on the cigarette pack?
Smoking is hazardous to your health!"
To which the man replies, "I am a programmer.
We don't worry about warnings; we only worry
about errors."
