- Text data processing
- Distributed processing
- Graphics, and other applications
- How to get started with Python
  - Install Python from python.org
  - Use an IDE (e.g., PyCharm, Visual Studio Code) or a text editor (e.g., Sublime Text, Atom, Notepad++) to write the code.

Basic Syntax and Data Types in Python

Variables: Containers used to store data values
Operators: Arithmetic, assignment, comparison, and logical, perform operations on data.
Data types: Integers, floating-point numbers, strings, and booleans. Examples of variables declaration

Arithmetic Operations

Symbols corresponding to the task and their examples and results

Comparator Operators

Symbols including ==, !=, <, >, <=, and >= for equality, inequality, less than, greater than, less than or equal to, and greater than or equal to.

Flowcharts

Graphical representation of a program's flow.
Four basic shapes used in flowchart:
- Oval: Start and end
- Parallelogram: Input and output
- Rectangle: Calculations
- Diamond: Selection structures
Arrows connect the shapes, tracing the program's flow from start to end.

Sequential Python Code

Examples and explanation to demonstrate writing sequential Python code.
Important lesson: variables of different types are not compatible, need to perform type conversion.
Casting: converting variables to different types (e.g., int(), float(), str()) in order to solve type mismatch and perform operations.
Order of precedence of operators in Python
