This document provides an introduction to the basics of Python programming language. It discusses that Python is a simple, human-readable language used for a variety of tasks like desktop, web, and mobile applications as well as artificial intelligence. Python has few data types (int, float, string) and a simple syntax without semicolons. The print command is used to output text and values, and variables do not require data types and can be of different types.

2. What is Python?
• It is a high level programming language, it is simple to write and read.
• It is a human readable
• It use for all thing …. Like (desktop programming – Web Application
programming – Mobile Programming - Artificial Intelligence – computer
hardware …etc.)
• Object oriented programming – open source.

3. Why Python?
• Easy to learn.
• You can do any thing using it.
• Just when you know the basics you can write any program.
• Simple data types.
• Very simple syntax.
• No semicolons (;)

4. Data types
• There is no a lot of datatypes in python:
• Int
• Float
• String
• That’s it
• Any variable is in one of this data types.

5. Print command
• It is used for print
• It’s syntax is ( print(thing I want to print) )
• Just in this simple.
• We can use (‘ ‘) or (“ “) for printing the string
• We just put variable name for printing it’s value
• We can use (,) or (+) to print more than one value.

6. Print command examples
• print(‘hello world’)
• print(“Hello world”)
• The difference here if we want to print this string (‘My name’s Ali’).
• This will give an error.
• To remove the error we must write like this print(“my name’s Ali”).

7. Print command example
• We can use print command for some math operators like (+ , - , * ,/)
• So we can simple write: print(3+4)
• Or write: print(4-1)
• Or write: print(4/2)
• Or write: print (4*2)
• Or write: print (4%2)

8. Variables in Python
• We just put name and value we don’t have to put data type
• Just like this:
x=5
• If we write x or print(x) the result will be: 5
• We can know the type of x if we write: print(type(x))
• The result will be <class ‘int’>

9. Print command example
• In all programming language we cann’t write command like (“x”*5)
• But in python we can
• If we write: print(“x”*5) the result will be:
• xxxxx
• But we cann’t write (“x”+5) because x is a string and 5 is an int
• We will solve this problem latter.
