python
- it is a popular progaramming
- Used by mathematicians,
scientists ,bankers, data
anlayists and even kids
- It is easy to use and
programme with it is even used
to make artificial intelligence.

- IDLE- integrated
development
enviroment
- when coding go to search
and type idle it will come
up if it is downloaded on
your computing
- There are 2 modes: Interactive
mode lets you see your results as
you type them, this mode uses
the Shell window. The second
mode is Script mode. script mode
lets you save your program and
run it again later,this mode uses
the Editor window

- ALGRITHMS
- If all correct simple steps
are in the right place
when solving a probelm
precisely it is called an
algrithm
- When you break a
probelm in to small and
simple steps, you make
an algrithm this is called
de-composition

- CODING
- In IDLE's Interactive Mode, at the prompt,
type: print("Hello World!"), Press Enter, the
result will be : Hello World! Remember to
spell print correctly and place the speech
marks and brackets in the correct places or
else the programme will not work correctly
- USING SCRIPT
MODE
- In the Shell window, select File, New File from
the menu Type: print ("What is your name?")
firstname = input() print ("Hello, ",firstname)
Save the program as MyFirstPython.py Select
Run, Run Module or press F5 to execute (run) the
program

- COMPUTER BUGS
- The name ‘Bug’ refers to an
error in a program Thought to
come from a real bug that
crawled into some cogs in an
early machine and stopped it
working
- DE-BUGGING
- Syntax errors Reading interpreter feedback
Traceback (most recent call last): File
"<pyshell#0>", line 1, in <module> primt
("Hello World!") NameError: name 'primt' is
not defined

("Hello World!") NameError: name 'primt' is
not defined

- FUNCTIONS
- Functions are special built-in
routines that do a specific job
Functions appear in purple
print() and input() are examples
of functions

- VARIABLES
- A variable is a location in
memeory in which you
can temporarily store
text or numbers because
you can change the
variable to a different
value
- A variable name
can contain only
numbers,letter
and underscores
- A variable
cannot start
with a
number
- you cant use python
"reserved word" as a
variable name- fro
example class is a
reseved word so
class=imput() will result
in a syntax
- To make your programme easier
to understand, use meanigful
name for your variables such as
"firstName" rather than "vart"

- SEQUENCING
INSTRUCTIONS
- Sequencing instruction is when you
pur steps one after the other. You
need to use sequencing in coding. So
the computer will do everything
correctly
- Sequencing instructions-the sequence order is
important, Accuracy is important
