PYTHON PROGRAMMING (CS721PE)COURSE PLANNERI.COURSE OVERVIEW:Python Programming is intended for software engineers, systems analysts, programmanagers and user support personnel who wish to learn the Python programming language. ThisPython for beginners training course leads the students from the basics of writing and runningPython scripts to more advanced features such as file operations, regular expressions, working withbinary data, and using the extensive functionality of Python modules. Extra emphasis is placed onfeatures unique to Python, such as tuples, array slices, and output formatting.II.PRE-REQUISITES:Experience with a high level language (C/C , Java, MATLAB) is suggested. Prior knowledge ofa scripting language (Perl, UNIX/Linux shells) and Object-Oriented concepts is helpful but notmandatory.III. COURSE OBJECTIVIES: To be able to introduce core programming basics and program design with functions usingPython programming language. To understand a range of Object-Oriented Programming, as well as in-depth data andinformation processing techniques. To understand the high-performance programs designed to strengthen the practicalexpertise.Course PurposeThis course PYTHON PROGRAMMING is an essential part of any Computer-Scienceeducation. To master the fundamentals of writing Python scripts, learn core Python scriptingelements such as variables and flow control structures, discover how to work with lists andsequence data, write Python functions to facilitate code reuse ,use Python to read and write files,make their code robust by handling errors and exceptions properly, work with the Python standardlibrary, explore Python's object-oriented features , search text using regular expressions and finallyworking with GUI (Graphical User Interfaces)IV.COURSE OUTCOMES:S.Bloom TaxmonyCourse Outcomes (CO)No.After completing this course the student must demonstrate the knowledge and ability to:Examine Python syntax and semanticsL4 AnalyzeCO1 and be fluent in the use of Python flowcontrol and functions.Demonstrate proficiency in handlingL3 ApplyCO2Strings and File Systems.Create, run and manipulate PythonL6 CreatePrograms using core data structures likeCO3Lists, Dictionaries and use RegularExpressions.Interpret the concepts of ObjectL3 ApplyCO4 Oriented Programming as used inPython.Implement exemplary applicationsL6 CreateCO5related to Network Programming, WebIV CSE B.TECH I SEMPage 42

site "Python 2.x is legacy, Python 3.x is the present and future of the language". In addition, "Python 3 eliminates many quirks that can unnecessarily trip up beginning programmers". However, note that Python 2 is currently still rather widely used. Python 2 and 3 are about 90% similar. Hence if you learn Python 3, you will likely
There are currently two versions of Python in use; Python 2 and Python 3. Python 3 is not backward compatible with Python 2. A lot of the imported modules were only available in Python 2 for quite some time, leading to a slow adoption of Python 3. However, this not really an issue anymore. Support for Python 2 will end in 2020.

In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The jet of abrasive particles is carried by carrier gas or air. High velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet. Nozzle directs the abrasive jet in a controlled manner onto .
