PROGRAMMING

1. VARIABLES

   • A VARIABLE IS A LOCATION IN WHICH YOU COULD TEMPORARILY STORE LETTER OR NUMBERS
   • RULES FOR NAMING VARIABLES
     • A VARIABLE CAN ONLY CONTAIN NUMBERS, LETTERS AND UNDERSCORES
     • A VARIABLE NAME CAN'T START WITH A NUMBER
     • TO MAKE YOUR PROGRAMS EASIER TO UNDERSTAND, USE MEANINGFUL NAMES FOR YOUR VARIABLES, SUCH AS 'firstName' RATHER THAN 'var1'

2. SYNTAX ERRORS

   • SYNTAX ERRORS OCCUR WHEN A PROGRAM DOES NOT FOLLOW TO THE GRAMMAR OF THE PROGRAMMING LANGUAGE
   • WHEN YOU DO A SYNTAX ERROR IN PYTHON, THE WRITING WILL BE RED

3. DATA TYPES

   • THERE ARE FOUR DATA TYPES
     • STRING: HOLDS ALPHANUMERIC DATA AS TEXT
     • INTEGER: HOLDS WHOLE NUMBERS
     • FLOAT: HOLDS NUMBERS WITH A DECIMAL POINT
     • BOOLEAN: HOLDS EITHER 'TRUE' OR 'FALSE'
