Python-Strings and Variables

1. You must use a set of instructions from the computer to follow

2. For the computer to solve the problem you must break down the problem into small, simpler tasks this is called: decomposition.

3. Algorithms are the different, precise steps to solve the problem-a set of instruction

4. A sequence is the consecutive order in which the computer has to solve the problem

5. A Syntax error is an error in the source code

6. In computing, a bug is an error in the coding

7. IDLE-Integrated Development Environment

8. A variable is a name memory location-temporary valuables
