How to Write Python Script Video Lecture - IT & Software

Can you tell me how to write Python script?
Python has a large code library online.
You could probably find a code module that
does what you want.
I need to know how to write what isn't in
the modules as well as how to thread them
together.
One of the best ways to learn how to write
Python script is to read about the proper
methods.
Methods are the functions, right?
Java uses methods, but Python's functions
are the same thing.
How else is programming in Python different?
Python is much more compact and efficient
than Java.
You can write a command or function in half
or a third of the lines of Java.
Let's start near the beginning.
How would I write the Hello World program
in Python?
If you want to do the classic Hello World
program, save the phrase to a file with a
print statement in front of the statement
Hello World.
That creates a text file with the words.
How do I activate it?
Go to the Python shell and type the command
python Helloworld.py or whatever you named
the file.
It ought to be dot py if you want to run it
as a Python program.
And once you tell Python to run it by writing
python program name, it will run.
The result should be Hello World.
Don't I have to compile it?
One of the beauties of Python is that it doesn't
need to be compiled.
It is interpreted real-time.
I'd hope that time was real.
If it isn't, the code is the least of our
problems.
One advantage of Python over compiled code
is that you can run what you just typed to
test it for errors.
Another is that you can fix a defective code
module while the rest is still running.
As long as the project itself does not run
off a cliff.
