This document discusses classes and objects in Python. It defines a Calculator class and demonstrates how to create class attributes, methods, and instances. It explains the __init__ method, self keyword, and how to access attributes and methods. It also covers data attributes versus class attributes, inheritance, method overriding, and calling parent methods. The document provides examples to illustrate these object-oriented programming concepts in Python.

This document discusses namespaces, global variables, and docstrings in Python. It explains that namespaces are like dictionaries that keep track of variable names and values. There are local, global, and built-in namespaces. Variables defined outside functions are global and can be accessed from anywhere, but reassigned locally without changing the global value unless declared global. Docstrings provide documentation for modules, functions, classes and are accessed with object.__doc__.
The document is about Python's datetime module. It introduces the module and the key classes it contains for manipulating dates and times, including Date, Time, and DateTime objects. It shows how to create datetime objects from these classes, extract attributes like year and hour, and perform operations like adding or subtracting days to manipulate dates. Examples are provided demonstrating common datetime tasks in Python like printing dates in different formats, finding today's date, and comparing datetime objects.
This document provides an overview of the math module in Python. It demonstrates how to import the math module and use common mathematical constants like pi and e. It also shows various math functions for calculating ceilings, floors, factorials, powers, square roots, logarithms, exponents, and converting between radians and degrees. The document contains examples of using these math functions and provides a brief description of their usage.
This document discusses exception handling in Python. It explains that exceptions are errors that occur during program execution and can be handled using try, except, and raise keywords. The document covers throwing exceptions, catching exceptions using try/except blocks, propagating exceptions, using try/except/else and try/except/finally, and some common built-in Python exceptions. It also provides an example of defining a custom exception class.
The document discusses the os and sys modules in Python. It provides examples of how to use common os functions like rename, remove, mkdir, and listdir to work with files and directories. It also demonstrates how to use the sys module to access command line arguments and exit a program. Key functions covered include getcwd(), chdir(), split(), splitext(), join(), argv, and exit.
This document discusses various methods for reading and writing files in Python, including open(), read(), readline(), readlines(), write(), seek(), and tell(). It provides examples of opening files, reading the contents, writing new text, and changing the file position. The open() function is used to open a file and return a file object, which then has various methods that can be called to perform operations on the file.
This document contains the details of a quiz competition with two written rounds consisting of 5 questions each. The first round involves identifying book covers, authors, literary works etc. The second round involves identifying the original names of popular writers who wrote under pen names or pseudonyms. The document provides the questions for both rounds and spaces to write answers. It mentions the scoring criteria and wishes the participants good luck.
