PYTHON

PYTHON

worlds fastest programming language
1. used by software engineers,mathematicians,data analysists even kids
  1. can be used for artificial intelligence
Algorithm is the different, precise steps to solve a problem in computing.
1. Algorithm is given to computers to solve the problem
  1. If all coding is in the right order when solving a problem in computing, it is called algorithm
2. Algorithm would be the simplest steps available
  1. Breaking down a problem into smaller bits is called DECOMPOSITION
    1. by doing this it leads to an algorithm
SEQUENCING
1. when you do something one after the other
PYTHON'S DEVELOPMENT ENVIRONMENT
1. is called IDLE - Integrated Development Environment
  1. has two modes- interactive mode and script mode
    1. interactive mode lets you see your results as you type them
DE-BUGGING
1. MEANS TAKING ERROR OUT OF THE CODE
VARIABLE
1. A variable is a location in memory which you can temporarily store text or numbers
  1. its not permanent because we can change it
    1. e.g. x=1 y=2 x+y=z so z=3 but because we can change the value of x and y and z, it is temporary
2. variable can only contain numbers,letters and underscores
  1. a variable name cannot start with a number
    1. in python you cant use a python reserved word as a variable name e.g.class is a reserved word so class=input would result in an error
      1. to make programs easier to understand, use
