Python Programming – Accepting Input From The Console In Python, input is used to request and get information from the user, and print is used to display information on the screen. input ( ) In Python, input is accomplished by using an assignment statement combined with a special function called input( ). Syntax of input ( ) is as follows: variable = input(<prompt>) Here, the prompt is an expression that serves to ask the user for input; this is almost always a string literal (i.e., some text inside quotation marks). When Python encounters an input expression, it evaluates the prompt and displays the result of the prompt on the screen. It then pauses and waits for the user to type an expression and press the Enter key. The expression typed by the user is then evaluated to produce the result. As the input provided is evaluated, Python expects a valid expression. If the input provided is not correct then either syntax error or exception is raised by Python.

Python Program to Calculate the Average Score

Python Program to Calculate the Average Score

Overview This script will calculate the average of three values. Make sure to put in “int” before the raw_input function, since we are using integers. # Get three test score round1 = int(raw_input(“Enter score for round 1: “)) round2 = int(raw_input(“Enter score for round 2: “)) round3 = int(raw_input(“Enter score for round 3: “)) # Calculate the average average = (round1 + round2 + round3) / 3 # Print out the test score print “the average score is: “, average Happy Scripting Python Display Calendar Number Guessing Game in Python Python Code: Celsius and Fahrenheit Converter Also Read: Python Program to Check if Three Points are Collinear Must Try: GRASIM Pivot Point Calculator

Quick Sort A Tutorial and Implementation Guide

Quick Sort: A Tutorial and Implementation Guide

Prerequisites To learn about Quick Sort, you must know: Python 3 Python data structures – Lists Recursion What is Quick Sort? We are in the fifth and final tutorial of the sorting series. The previous tutorial talks about Bubble Sort, Insertion Sort, Selection Sort, and Merge Sort. If you haven’t read that, please do as we will be building off of those concepts. Like all sorting algorithms, we consider a list to be sorted only if it is in ascending order. Descending order is considered the worst unsorted case. Quick Sort is quite different and complicated from the sorting techniques we have seen so far. In this technique, we select the first element and call it the pivot. The idea is to group elements such that elements to the left of the pivot are smaller than the pivot and the elements to the right of the pivot are larger than the pivot. This is done by maintaining two pointers left and right. The left pointer points to the first element after the pivot. Let us refer to the element pointed by left as lelement. Similarly, the right pointer points to the farthest element on the right side of the list. Let us call this element as relement. At each step, compare lelement with pivot and relement with pivot. Insertion Sort:…

CommandLineFu with Python

CommandLineFu with Python

Overview One of the best methods to practice Python coding is to study some code and try them out yourself. By doing a lot of code exercises, you will get a much better understanding of what it really does. In other words, learning by doing. To help you improve your Python coding skill, I’ve created a program below which is using the API from CommandLineFu.com Bitly URL Shortener using Python How to use the Hacker News API How to use the Vimeo API in Python CommandLineFu API A common first step when you want to use a Web-based services is to see if they have an API. Luckily for me, Commandlinefu.com provides one and can be found here: “The content of commandlinefu.com is available in a variety of different formats for you to do what you like with. Any page which contains a list of commands (such as the listings by tag, function or user) can be returned in a format of your choice through a simple change to the request URL.” The example URL that they provide is: where: command-set is the URL component which specifies which set of commands to return.

Booleans, True or False in Python

Booleans, True or False in Python

What are Boolean? Boolean values are the two constant objects False and True. They are used to represent truth values (other values can also be considered false or true). In numeric contexts (for example, when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively. The built-in function bool() can be used to cast any value to a Boolean if the value can be interpreted as a truth value They are written as False and True, respectively.
