Python Program to find the sum of array
In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven an array as an input, we need to compute the sum of the given array.Here we may follow the brute-force approach i.e. traversing over a list and adding each element to an empty sum variable. Finally, we display the value of the sum.We can also perform an alternate approach using built-in sum function as discussed below.Example# main arr = [1, 2, 3, 4, 5] ans = sum(arr, n) print ('Sum of the array is ', ans)Output15 All the variables & functions are ...
Read MoreInsertion Sort in Python Program
In this article, we will learn about the implementation of Insertion sort in Python 3.x. Or earlier.AlgorithmIterate over the input elements by growing the sorted array at each iteration.Compare the current element with the largest value available in the sorted array.If the current element is greater, then it leaves the element in its place and moves on to the next element else it finds its correct position in the sorted array and moves it to that position in the array.This is achieved by shifting all the elements towards the right, which are larger than the current element, in the sorted ...
Read MoreWhich one is the Python module to obfuscate javascript?
You can use the jsmin module to minimize/obfuscate javascript code using Python. Install jsmin using:$ pip install jsminTo use jsmin in your python project to minimize a js file, say hello.js, you can use it as follows:>>> from jsmin import jsmin >>> with open('hello.js') as js_file: ... minified = jsmin(js_file.read()) >>> print minifiedYou'll get the minified JS code printed to your shell. You can also use jsmin as a command line tool:$ python -m jsmin hello.jsYou can read more about jsmin on pypi docs: https://pypi.python.org/pypi/jsmin
Read MorePython Program for Finding the vertex, focus and directrix of a parabola
In this article, we will learn about the solution to the problem statement given below −Problem statementThe standard form of a parabola equation is y=ax^2+bx+c. Input the values of a, b and c, our task is to find the coordinates of the vertex, focus and the equation of the directrix.The vertex of a parabola is the coordinate from which it takes the sharpest turn whereas y=a is the straight-line used to generate the curve.A directrix a fixed-line used in describing a curve or surface.Now let’s see the implementation −Example Live Demodef findparabola(a, b, c): print ("Vertex: (" , (-b / ...
Read MoreWindows 10 Toast Notifications with Python
We can create a notifier for the events that occurred in Windows using Python. This is very simple with the win10toast module. If you are familiar with the Toast in Android then understanding the Toast notifications with Python is a piece of cake. We can generate notifications whenever an event occurs as a remainder. Let's see.Run the following command in command-line to install win10toast modulepip install win10toastIf the module successfully installed then, you will get the following result when you run the command.Collecting win10toast Downloading https://files.pythonhosted.org/packages/d4/ba/95c0ea87d9bcad68b90d8cb130a313b939c88d8338a2fed7c11eaee972fe/win10toast-0.9-py2.py3-none-any.whl Collecting pypiwin32 (from win10toast) Downloading https://files.pythonhosted.org/packages/d0/1b/2f292bbd742e369a100c91faa0483172cd91a1a422a6692055ac920946c5/pypiwin32-223-py3-none-any.whl Requirement already satisfied: setuptools in c:\users\hafeezulkareem\anaconda3\lib\site-packages (from win10toast) ...
Read MoreHow to setup cookies in Python CGI Programming?
Setting up CookiesIt is very easy to send cookies to browser. These cookies are sent along with HTTP Header before to Content-type field. Assuming you want to set UserID and Password as cookies. Setting the cookies is done as follows −#!/usr/bin/python print "Set-Cookie:UserID = XYZ;\r" print "Set-Cookie:Password = XYZ123;\r" print "Set-Cookie:Expires = Tuesday, 31-Dec-2007 23:12:40 GMT;\r" print "Set-Cookie:Domain = www.tutorialspoint.com;\r" print "Set-Cookie:Path = /perl;" print "Content-type:text/html\r\r" ...........Rest of the HTML Content....From this example, you must have understood how to set cookies. We use Set-Cookie HTTP header to set cookies.It is optional to set cookies attributes like Expires, Domain, and Path. ...

Read MoreK'th Non-repeating Character in Python using List Comprehension and OrderedDict
In this article, we will learn about K’th Non-repeating Character in Python using List Comprehension and OrderedDict. To do so we take the help of inbuilt constructs available in Python.Algorithm1. First, we form a dictionary data from the input. 2. Now we count the frequency of each character. 3. Now we extract the list of all keys whose value equals 1. 4. Finally, we return k-1 character.Examplefrom collections import OrderedDict import itertools def kthRepeating(inp, k): # returns a dictionary data dict=OrderedDict.fromkeys(inp, 0) # frequency of each character for ch in inp: ...

In this article, we will learn about convolutions in Python 3.x. Or earlier. This articles come under neural networks and feature extraction.Ide preferred − Jupyter notebookPrerequisites − Numpy installed, Matplotlib installedInstallation>>> pip install numpy >>>pip install matplotlibConvolutionConvolution is a type of operation that can be performed on an image to extract the features from it by applying a smaller container called a kernel/coordinate container like a sliding window over the image. Depending on the values in the convolutional coordinate container, we can pick up specific patterns/features from the image.Here, we will learn about the detection of horizontal and vertical endpoints in ...
Read MoreInternal working of the list in Python
In this tutorial, we will learn about the internal working of the list in Python 3.x. Or earlier. We will also look at the object and frame formation when we write a python statement at each step.Initializing the list: This means that we are creating a list with some elements.>>> lis=[1, 2, 3, 4]Here list variable is declared in the global frame which is referring to a list object as shown aboveNow let’s see what happened when we append the element in the list.>>> lis.append(8)Here the element is added at the end and the size of the list is increased ...
