Chapters
Chapter 1 : Getting Started with Python Programming
In this section you will learn about getting started with Python programming.
You will see what is Python? What is it used for? How do you install Python? How do you use Python?
Chapter 2 : Python Fundamentals
This section introduces you to the fundamentals of Python programming.
Here you will learn about syntax, number, string, variables, data types, constant, Booleans, comments, type conversion, Operators, etc.
Chapter 3 : Python – Control Flow
Control flow is one of the most important aspects of any programming language.
In Python, control flow is handled by if-else statements, while loops, for loops, break, continue, return, pass, raise, try, except, finally, yield, and more.
Chapter 4 : Python – Functions
Functions are blocks of code that can be reused across different parts of your program. They are also known as subroutines or methods.
In this section, you will learn everything about python functions, How to create?, How to use?, etc.
Chapter 5 : Python – Lists & Directories
Lists are containers which store elements. The elements stored in lists may be strings, numbers, tuples, dictionaries, sets, etc.
You will learn all about list operations like append(), insert(), remove(), sort(), reverse(), find() and many others.
Also, you will learn about directories and their usage.
Chapter 6 : Python – Sets
Sets are collections of unique items. They are similar to arrays but they don’t have fixed size.
You will understand set operations like union(), intersection(), difference(), symmetric difference(), complement(), power set(), etc.
Also, you will learn about set comprehension.
Chapter 7 : Python – Exception Handling
Exceptions are errors that occur during execution of programs. These errors are usually caused due to bugs in the code.
You will know about exceptions like TypeError, NameError, IndexError, ValueError, OverflowError, ArithmeticError, MemoryError, SyntaxError, IndentationError, UnicodeEncodeError, UnicodeDecodeError, AttributeError, IOError, EOFError, EnvironmentError, ImportError, SystemExit, GeneratorExit, KeyboardInterrupt, RuntimeError, and so on.
You will also learn how to handle these exceptions using try/except statement.
Chapter 8 : Python – Working with Files
Working with files is very easy in Python. It has built-in support for reading and writing text files. Also, there are modules available to read binary files.
You will get to know about file handling operations like open(), close(), write(), read(), seek(), tell(), truncate(), flush(), close(), etc.
Chapter 9 : Python OOP – Classes and Objects
Object oriented programming (OOP) is a paradigm where objects interact with each other through inheritance and polymorphism.
You will learn classes and objects in Python. You will learn about object creation, attributes, methods, class hierarchy, superclass and subclass relationship, etc.
Chapter 10 : Python OOP – Special Methods and Property
Special methods and properties are used to access private members of an object.
You will see special methods like __init__(), __repr__(), __str__(), __add__(), __sub__(), __mul__(), __div__(), __truediv__(), __floordiv__(), __mod__(), __pow__(), __and__(), __or__(), __xor__(), __pos__(), __neg__(), __nonzero__(), __len__(), __getitem__(), __setitem__(), __delitem__(), __contains__(), __iter__(), __eq__(), __ne__(), __lt__(), __gt__(), __le__(), __ge__(), __cmp__(), __hash__(), __reduce__(), __format__(), __dir__(), __doc__(), __name__(), __package__(), __module__(), __loader__(), __annotations__(), __dict__(), __weakref__().
You will also learn property related topics like attribute lookup, descriptor protocol, property decorator, etc.
Chapter 11 : Python OOP – Inheritance and Enumeration
Inheritance is one of the most important concepts in OOP. In this section, you will learn about inheritance in Python. You will also learn about enumeration.
You will be able to create your own classes by inheriting from existing ones. You will also learn how to use multiple inheritance.
Chapter 12 : Python OOP – Descriptor, Metaprogramming, and Exceptions
Descriptors are used to define custom behavior for a class or instance. They can be defined at class level or instance level.
Metaprogramming is the process of creating new functionality without modifying source code. This is done by manipulating program data structures instead of their representation.
You will be introduced to metaclasses and descriptors in Python. You will be taught about exception handling in Python.
Chapter 13 : Python for Advance Programmer
In this section you will learn advance techniques and methods in python to become an advance programmer.
You will learn advanced features of python such as generators, list comprehensions, generator expressions, map() function, filter() function, reduce() function, zip() function, iter tools module, lambda functions, operator overloading, dynamic typing, duck typing, etc.
You will understand how to use them effectively in real world applications.
Chapter 14 : Python Regex
Regex is a powerful tool that helps us to find patterns in strings. It is very useful when we need to search for patterns in text files or web pages.
You will get to know about regular expression syntax, different types of regex engines, basic usage of re module, using re.compile() method, matching groups, capturing groups, named groups, lookahead assertions, lookbehind assertions, quantifiers, back references, character sets, Unicode support, etc.
This section will help you to write robust and efficient programs.
Chapter 15 : Python Unit Testing
Unit testing is a technique which allows us to test individual units of our software independently. You can run unit tests on each file separately.
You can execute unit tests with various parameters and assert if they pass or fail.
You will learn about unit test module, nose framework, pytest framework, mock objects, patch object, etc.
