Python

1. What is Python?

   • It is a popular programming language

2. Codes

   • Comments make it easier to understand your code
     • It will not affect the way the program runs
     • Comments start with a # symbol and appear in red

3. Terms

   • Decomposition - the simplest tasks to follow or solve a problem
   • Algorithm - a process or set of simple steps, in order, to follow to solve a problem
   • De-bugging is to fix the errors in the code
   • A variable is a location in memory in which you can temporarily store text or numbers
     • A variable can only contain numbers, letters and underscores
     • A variable can't start with a number
     • You can't use a Python reserved word as a variable name - for example "class" is a reserved word so "class=input()" will result in syntax error

4. Why Python?

5. Py

   • Saved as py so the computer knows that it is a python document
   • The computer will know what software to open it on
