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) ...

In this article, we will learn about the tools to support Data Science other than Python and R?Here we will look at five tools that help in implementing the concept of data science.Apache HadoopJava-based free softwareLarge storage capabilityThe splitting capacity of dataNosqlMore structured orientationBetter performance efficiencyOpen-source software efficiencyHiveDistributed data management systemHighly useful in data miningTorchScientific computing frameworkIt uses Lua programming languageIt can easily implement deep learning algorithmsDomino data labUnified data science toolIncreases iteration speedRemoves deployment frictionConclusionIn this article, we learned about some of the powerful tools available in the field of data science other than Python & R.

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 ...

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 ...

In this article, we will learn about defining and user-defined functions to predict the next greatest element.Problem statementWe are given an array & we need to print the Next Greater Element for every element present in the array. The Next greater Element for an arbitrary element y is the first greatest element present on the right side of x in array. Elements for which no greatest element exist, return -1 as output.4Input test case[12, 1, 2, 3]Output12 -> -1 1 -> 3 2 -> 3 3 -> -1Now let’s observe the source code.Example# Function Def elevalue(arr):    # Iteration   ...

In this article, we will learn the implementation and usage of issubset() function available in the Python Standard Library.The issubset() method returns boolean True when all elements of a set are present in another set (passed as an argument) otherwise, it returns boolean False.In the figure given below B is a subset of A. In case A & B are identical sets mean that A is a proper subset of B. This means both sets contain the same elements in them.Syntax.issubset()Return valueboolean True/FalseNow let’s look at an illustration to understand the concept.Example Live DemoA = {'t', 'u', 't', 'o', 'r', 'i', ...

In this article, we will learn about Input/Output from an external files in C/C++, Java, and Python for Competitive Programming.Python I/O from the fileIn python, the sys module is used to take input from a file and write output to the file. Let’s look at the implementation in the form of code.Exampleimport sys # For getting input sys.stdin = open('sample.txt', 'r') # Printing the Output sys.stdout = open('sample.txt', 'w')Java I/O from the fileHere we take the help of buffered reader method to take input associated with file reader to read input from file and print writer to print the data ...

In this article, we will learn about some Interesting facts about strings in Python 3.x. Or earlier.ImmutabilityAuto-detection of escape sequencesDirect slicingIndexed accessImmutabilityThis means that there is no permission of modification on type and we only have read only access to the strings.Exampleinp = 'Tutorials point' # output print(inp) # assigning a new value to a particular index in a string inp[0] = 't' print(inp) # raises an errorOutputTypeError: 'str' object does not support item assignmentAuto-detection of escape sequencesThe strings containing backslash are automatically detected as an escape sequence.Exampleinp = 'Tutorials point' # output print(inp+””+”101”)OutputTutorials point 101Direct slicingWe all are aware ...
