History of Python
Python was conceived in the late 1980s by

Guido van Rossum
First appeared in February 1991: 30 year ago
Python 2.0 was released in 2000
Python 3.0 was released in 2008
Python 3.0 is a major revision of language and is not compatible with python 2
Since January 1, 2020 python 2 is no longer supported
Python 3.9 is the last python version for now

Слайд 6

What is Interpreter
Program
Executes instructions written in a high-level language
Process code at

a run time
Checking the code for errors line by line
No Object Code is generated, hence are memory efficient.
Programming languages like JavaScript, Python, Ruby use interpreters.

Слайд 7

What is compiler
Program
Takes the entire program as input
Generate machine code
Checking the

code for errors during compilation process
Compiled program takes more memory
Example of programming languages that use compilers: C, C++, Java, COBOL

Слайд 8

Compiling process

Слайд 9

Python Interpreter

Слайд 10

Python Installation
Python installation link https://www.python.org/downloads/
Download python 3.x version
Open the .exe file
Follow

the installation instructions
Add python3.x to PATH
Open python 3.x interpreter user interface
Print “hello team” text

Слайд 11

Code Editor vs IDE
Developer’s tool designed to edit the source code

of computers programs
Text editor with powerful built-in features
Key features
Syntax highlighting
Printing
Multiview
Preview window
Code editors
Atom
Sublime Text
Notepad++
VIM
Visual Studio Code

Integrated Development Environment
Set of software development tools designed to make coding easier.
Key features
Text editing
Debugging
GUI
Syntax highlighting
Unit testing
Code completion(Autocomplete)
IDE’s
NetBeans
Eclipse
IntelliJ
Visual Studio
PyCharm

Слайд 12

Visual Studio Code
Built-in open source-code editor made by Microsoft
Cross-Platform
Fast
Embedded Version Control
Use

less memory
Support a huge amount of languages

Слайд 13

Visual Studio Code Installation
Download the Visual Studio Code installer for Windows

(32 or 64 bit, depending on your system)
https://code.visualstudio.com/download
Run the installer VSCodeUserSetup-{version}.exe
Follow the instructions
Select “Create a desktop icon” checkbox
Select “Add to PATH” checkbox
By default, VS Code is installed under C:\users\{username}\AppData\Local\Programs\Microsoft VS Code
Launch Visual Studio Code

Слайд 14

Visual Studio Code Setup
Open EXTENSIONS toolbar(Ctrl+Shift+x)
Type Python and Install python extension

for Visual Studio Code
Create a folder somewhere in your computer
Select the folder what you created by File->Open Folder
Create a new file with .py extension
Write print(“Hello Team”) text
Select python interpreter(Ctrl+Shift+p)
Type “Python interpreter” and select interpreter
Open the terminal (View->Terminal or Ctrl`)
Run you code (python some_file.py)
Congratulations!!!

Version Control Systems
Process management system
Also called revision control system
Maintain changes

recorded in a file or set of files over period of time.
Each change is maintained as a version
User can track specific versions later
Allow to compare different versions

Слайд 16

Version Control Systems Types
Local Version Control System
Maintains track of files within

the local system
This approach is very common and simple
This type is also error prone which means the chances of accidentally writing to the wrong file is higher.
Tools
RCS

Слайд 17

Version Control Systems Types
Centralized Version Control Systems
Files are tracked under the

centralized sever
Single server that contains all the versioned files
Everyone knows to a certain degree what everyone else on the project is doing
Disadvantages
Single point of failure
Tools
Tortoise SVN
CVS
Bazaar
Subversion
Perforce

Version Control Systems Types
Distributed Version Control Systems
Fully mirror the repository, including

its full history
Every clone is really a full backup of all the data
Several remote repositories
Availability collaborate with different groups of people in different ways simultaneously within the same project
Allow set up several types of workflows
Tools
Git
Mercurial

GIT
First developed by the creator of Linux kernel, Linus Torvalds in

2005
Goals
Speed
Simple design
Strong support for non-linear development(thousands of parallel branches)
Fully distributed
Stores series of snapshots of a miniature filesystem
If file is not changed GIT make a link to the previous identical file it has already stored
