Unit iii functions, arrays fruitful functions: return values, parameters, local and global scope, function composition, recursion; strings: string slices, immutability, string functions and methods, string module; python arrays, access the elements of an array, array methods.
Python Programming Pdf Variable Computer Science Python Python language statements that tell the computer what to do get user input, display output, set values, do arithmetic, test conditions, repeat groups of statements,. A variable is a named location used to store data in the memory. it is helpful to think of variables as a container that holds data which can be changed later throughout programming. Introduction python is a popular high level, general purpose programming language. guido van rossum invented it in 1991, and the python software foundation continued to advance it. programmers may convey their ideas in less code because to its syntax, which was created with code readability in mind. •variables are the basic unit of storage for a program. •variables can be created and destroyed. •at a hardware level, a variable is a reference to a location in memory. •programs perform operations on variables and alter or fill in their values.

Before we get familiarize with python functions, it is important that we understand the indentation rule to declare python functions and these rules are applicable to other elements of python as well like declaring conditions, loops or variable. Explain identifiers, variable, constants, assignment and expressions used in python. identify basic concepts of input and output . apply string manipulation techniques in python. This is our first python program. it is customary to have a programmer's first program write "hello world" (inspired by the first program in brian kernighan and dennis ritchie's classic book, 'the c programming language.'). Under unix systems, a standard technique for running programs written in languages like python is to include a specially formed comment as the first line of the file, informing the shell where to find the interpreter for your program.
