Study Notes
- Here are detailed study notes on Introduction to Python & Programming Basics, Iteration and functions in Python, Data Structures in Python, Object-Oriented Programming in Python and Python for Engineering Applications and Advanced Topics:
Introduction to Python & Programming Basics
- Python's importance in engineering and its programming paradigms are the focus
- Setting up the Python environment involves using tools like IDLE, Jupyter Notebook, and Anaconda
- Python syntax encompasses data types, writing, and executing scripts
- Indentation, commenting, and debugging are key aspects of Python coding
- Variables and operators, including arithmetic, relational, logical, bitwise, and assignment types, are covered
- Input/Output operations cover accepting user input via input() and displaying output using print()
- Formatted output is achieved using f-strings
- Control structures, focusing on conditional statements, and decision-making constructs are used
Iteration and Functions in Python
- Loops and iteration cover for and while loops, nested loops, and break/continue statements
- Loop control flow is discussed
- Python functions cover defining functions, arguments, return statements, positional and keyword arguments
- Lambda functions, recursion, efficiency, scope, and variable lifetime are all discussed
- Exception handling covers handling runtime errors using try-except blocks, raising exceptions, and using finally
Data Structures in Python
- Lists cover creating, accessing, modifying, list comprehension and iterating through lists
- Tuples and sets are immutable sequences, sets support union, intersection, and difference operations
- Dictionaries include key-value pair structures and dictionary methods, along with comprehensions
- String handling emphasizes string manipulation, formatting, built-in string methods, raw strings, and regular expressions
- File handling includes reading and writing text files with various functions and handling file exceptions
Object-Oriented Programming in Python
- Object-oriented programming involves classes, objects and a comparison with procedural programming is made
- Class definition includes constructors (init method), instance variables, and methods
- Encapsulation and abstraction cover Data hiding with access specifiers, and getter/setter methods
- Single, multiple, multilevel, and hierarchical inheritance and polymorphism are covered
- Method overriding and the
super()function are discussed - Modules and packages cover importing built-in and creating user-defined Python packages for organizing large-scale projects
Python for Engineering Applications & Advanced Topics
- Python libraries include NumPy for array and matrix operations, pandas for data manipulation, and Matplotlib for data visualization
- Data analysis is performed with Python
- Reading and writing structured data, data wrangling, and basic statistics are performed with Python
- Introduction to machine learning involves an overview of AI/ML and using scikit-learn for simple classification problems
- Automating tasks uses Python for repetitive tasks, file handling, web scraping, and API interactions
- Project-based learning involves students working on a real-world problem using Python, integrating concepts from previous units into a functional solution
