12. Introduction to Programming
⚫ The process of creating computer programs is
called programming
⚫ A program is known as a recipe for a computer
⚫ A recipe is a step by step procedure
⚫ In programming terms, this recipe is called an
Algorithm
13. Programming Language
⚫ Instructions for a computer are expressed in a
programming language.
⚫ A programming language is an artificial language
that can be used to control the behavior of a
machine, particularly a computer.
15. Why Python?
⚫ Python is called a high-level programming
language.
⚫ A high-level programming language is a
programming language that is:
1. more abstract,
2. more easy to use, and
3. more portable across platforms
16. High Vs Low Level Programming
Languages
⚫ High-level languages are closer to humans.
⚫ Low-level languages are closer to machines.
Machine code:
Instructions that a particular processor can
understand and execute.
Humans almost never write programs directly in
machine code!
18. Topic 1
Introduction to interpreted
programming languages
>> setting the
environments rights
Python Programming
19. The way of a Python Program
Interpret:
⚫ To execute a program line by line.
Compile:
⚫ To translate a program for later execution.
Execute (by a computer):
⚫ To carry out the instructions.
Interpreter Vs Complier
22. Python
⚫ Python is usually interpreted.
⚫ Python can also be compiled.
– But this is done in the very last stage.
– To create "ready-for-use" programs.
23. What is a Code?
⚫ The text of a program is called:
- the source code
- the script.
⚫ The compiled text of a program is
called:
- the object code
- the executable
- the byte code
