1. Getting Started

✌ What is Python ?

✌ Installing Python

1. Download python from python.org
2. Run the installer, check 'Add Python 3.10 to PATH', and install.
3. Check the python version in the command prompt by using python command.
4. Download the latest version of VSCode editor from code.visualstudio.com
5. Add Python extension from marketplace.

✌ Your First Python Program

1. Create app.py and open it in VS Code.
2. Run the file in the terminal using python app.py

2. Primitive Types

✌ Variables

• Variables are used to store values in a computer's memory.
• Python is a case-sensitive language.

✌ Variable Names

• Variable names should be meaningful and descriptive.
• lowercase is used for naming
• Underscore(_) is used to separate multiple words
• space around =

✌ String

✌ Escape Sequences \" , \' , \, \n

✌ Formatted Strings

✌ String Methods

✌ Numbers

✌ Working with Numbers

✌ Type Conversion int(x), float(x), bool(x), str(x)

3. Control Flow

✌ Comparison Operators

✌ Conditional Statements

✌ Ternary Operator

✌ Logical Operators and,or,not

✌ Short-circuit Evaluation

✌ Chaining Comparison operators

✌ For Loops

✌ For..Else

✌ Nested Loops

✌ Iterables

✌ While loops

✌ Infinite Loops

4. Functions

✌ Defining Functions

✌ Arguments

✌ Types of Functions

✌ Keyword Arguments

✌ Default Arguments

✌ *args

✌ **args

✌ Scope

✌ Debugging (VERY IMPORTANT) : find and fix the bug

• Run and debug -> Create launch.json file -> Python file

• F9 -> insert a breakpoint

• F5 -> run the application to this point

• F10 -> execute one statement at a time

• If we press F10 again execution stops

• This time we want to step inside this multiply function so instead, press F11

• Now we go inside the multiply function

• Press F10 to go to the next line

• Shift + F5 -> to stop the debugger

• If we find the problem is a function set debug point inside that function

• If we find everything is alright inside a function, use Shift + F11 -> to step out of that function

✌ VSCode Shotcut Windows

• Home : beggining of line

• End : end of line

• Ctrl + Home/End : begin/end of file

• Alt + Up/Down : move whole line up/down

• Shift + Alt + up/down : copy line

• Ctrl + / : comment
