Module IV_updated(old).pdf
Module IV_updated(old).pdfR.K.College of engg & Tech The document discusses classes and objects in Python programming. It covers key concepts like defining classes, creating objects, assigning attributes to objects, passing objects as arguments and returning objects from functions. It provides examples to illustrate these concepts like defining a Point class to represent coordinate points, creating Rectangle class with a Point object as one of its attributes. The document also discusses concepts like aliasing of objects and how to create a copy of an object instead of alias.
Module III.pdf
Module III.pdfR.K.College of engg & Tech The document discusses Python lists and their key features. It covers how lists are ordered sequences that can contain elements of different types. Lists are mutable and can be accessed using indexes. Common list operations include slicing, concatenation, repetition, sorting, and using various list methods like append(), extend(), index(), reverse() etc. Tuples are immutable sequences similar to lists. Dictionaries are another data type that store elements as key-value pairs. The document also briefly introduces regular expressions for text parsing and extraction.
Python_Module_2.pdf
Python_Module_2.pdfR.K.College of engg & Tech The document discusses different types of loops in Python including while loops, for loops, and infinite loops. It provides examples of using while loops to iterate until a condition is met, using for loops to iterate over a set of elements when the number of iterations is known, and how to terminate loops early using break or skip iterations using continue. It also discusses using the range() function to generate a sequence of numbers to iterate over in for loops.
Python_Module_1.pdf
Python_Module_1.pdfR.K.College of engg & Tech This document discusses why learning to program is useful, provides an overview of Python programming, and covers installing and getting started with Python. Key points include:
- Programs are written to solve problems computationally and humans tend to get bored with repetitive tasks, so programming allows computers to act as assistants.
- Python is a programming language that can be used on many devices and supports different data structures and algorithms.
- To communicate with the CPU to solve problems, one must write a set of instructions called a program. Installing Python or the Anaconda distribution allows you to start programming with Python.

Python for Data Analysis_ Data Wrangling with Pandas, Numpy, and Ipython ( PD...R.K.College of engg & Tech This document provides an overview and table of contents for the book "Python for Data Analysis" by Wes McKinney. The book covers using Python and essential Python data analysis libraries like NumPy, pandas, matplotlib, and others for data wrangling, exploration, and modeling. It includes chapters on data structures and manipulation, data loading and storage, data cleaning, aggregation, visualization, and more. The second edition was published in 2017 and builds on the first edition.
Ch-8.pdf
Ch-8.pdfR.K.College of engg & Tech This document provides an overview of Python data structures, focusing on lists and tuples. It discusses how lists and tuples store and organize data, how to define, access, update, and manipulate elements within lists and tuples using various Python functions and methods. Lists are described as mutable sequences that can contain elements of different data types, while tuples are described as immutable sequences. The document provides examples of using lists and tuples for tasks like stacks, queues, and storing records. It also covers list and tuple operations like slicing, filtering, mapping, and reducing.
Ch-5.pdf
Ch-5.pdfR.K.College of engg & Tech This document discusses Python functions and modules. It explains that Python allows programmers to break programs into independent segments called functions. Functions enable easier understanding, coding, testing and maintenance of programs. The document then covers various aspects of defining, calling and using functions in Python like function declaration, parameters, local and global variables, return values, recursion and importing from modules.

Functions enable easier understanding, coding, testing and maintenance of programs. The document covers function declaration, definition, calls, parameters, local and global variables, return statements, default arguments, anonymous functions, recursion and importing from modules.
Ch-4.pdf
Ch-4.pdfR.K.College of engg & Tech This document discusses control statements in Python programming. It covers sequential, selection, and iterative control statements including if, if-else, nested if, if-elif-else, while loops, for loops, break, continue, pass, and else statements used with loops. Control statements allow programmers to control the flow and execution of code by making decisions or repeating actions.
Ch-3.pdf
Ch-3.pdfR.K.College of engg & Tech The document provides an overview of the Python programming language. It discusses features of Python like being simple, easy to learn, versatile, free and open source. It also covers limitations of Python such as being slower than C/C++ for computation heavy tasks. The document describes applications of Python like web development, scientific computing, games development. It then explains basics of Python programming like writing the first program, data types, variables, operators, expressions and lists. Finally, it discusses type conversion and type coercion in Python.
Creating Interface- Practice Program 6.docx
Creating Interface- Practice Program 6.docxR.K.College of engg & Tech The document discusses how to define an interface in Java that specifies methods for generating different types of number series. An interface named Series is defined with three methods - getNext() to return the next number, reset() to restart the series, and setStart() to set the starting value. Classes can then implement the Series interface and provide implementations of these three methods to generate specific types of number series, like one that returns even numbers starting from 2.

Practice Program-9-Packages-Unit 4.docxR.K.College of engg & Tech Packages in Java help organize code by providing a layer of encapsulation and control. Packages group related classes and interfaces together, and allow classes to be made private to a package. To define a package, use the package statement at the top of a file with the package name. Multiple files can belong to the same package. Packages are hierarchical, with names separated by periods. Directories mirror package hierarchies.
Unit-3 Practice Programs-5.docx
Unit-3 Practice Programs-5.docxR.K.College of engg & Tech The document provides examples of multilevel inheritance in Java. In multilevel inheritance, a subclass inherits from an intermediate derived class, which itself inherits from a base class. This allows subclasses to inherit properties from all parent classes up the inheritance chain. Three programs are given as examples, demonstrating how subclasses can call constructors and methods of parent classes in the inheritance hierarchy.
