Screen Capture Using Python

Nowadays, screen capturing is one of the common tasks which most of us are doing in our day-to-day routine and there are instances where in we need to automate this task. In this article, I'll explain you about how can we automate screen capturing using Python. To get started, first of all we need to grab all the required packages and install them. Required packages To automate screenshot capturing, we need to install a package named pyautogui and this can be installed using pip as shown below: pip install pyautogui     Import packages Once required packages are installed, we need to import them into our code. Here we need to import two packages - one for screenshot capturing and another one is for timer as we need to capture our screen after certain seconds of our application launch. Here is the code: import pyautogui import time Implementation  Now we have all the packages imported, we can go ahead and make a call to required function. We will start by calling a function screen

Effective ways to sort Python iterables

The traditional way to sort iterables is by using loops, like for loop or while loop. As part of this article, I am not going to cover this traditional way, rather I will be focusing on a better way to implement sorting. And that better way is by using sorted function . Let's take a look at below list holding some numbers: numbers = [ 2 , 3 , 6 , 4 , 9 , 1 ] Python Copy To sort this list, we just need to call a function as shown below:  numbers = sorted ( numbers ) Python Copy To sort this list in reverse order, we need to pass an additional parameter: numbers = sorted ( numbers , reverse = True ) Python Copy Apart from this simple case, we can also handle some complex scenarios wherein we have a list containing key-value pairs as shown: studentDetails = [ { “Name” : “Nick” , “Marks” : 23 } , { “Name” : “Roy” , “Marks” : 2 } , { “Name” : “Honey” , “Marks” : 45 } ] Python Copy Now, say you want to sort studentDetails based on Marks. So, the only code you n

Create Word Art From An Image Using Python

If you are Python developer then you may be fully convinced that we can do very cool things using Python in very easy way. Today I’m going to show you a very beautiful usage of Python, in which we will see how we can generate a word art of any given image. You can pick an image of your pet, you can pick an image of a natural scenery, you can pick an image of human, basically you can pick anything as your image.  Once the image is selected, it is just the matter of few lines of Python code. Package To generate word art we need to install a package named pywhatkit . If you are using pip to install your Python packages, then here is the syntax: pip install pywhatkit Code Once the package is installed, you need to import the package and call the function named image_to_ascii_art(…) . This function will take two parameters — first one is the image file path and second parameter is the name for output file. Here are the two lines of code: import pywhatkit pywhatkit.image_to_ascii_art(“Wolf.p

Keep Your Screen Active Forever Using Python

If your boss is very workaholic and you are not working from office then you must have heard one of these statements from your boss: Why were you not at your desk  Why your status was away in Teams/Skype/etc I couldn't see you really putting 8 hours at work, blah blah blah. source: And all these statements are coming because your machine was inactive and that change your communicator status to Away . Well, so today we are going to solve this problem where in we will not let our communicator status change by its own. How can we do that? Answer is very simple. This problem can be solved, if our machine is active, if we are continuously (or in few mins) pressing some keys or moving our mouse.  Here we will use Python to write just few lines of code to perform this magic.  Python package We will use Python package named pyautogui as it allows us to automate mouse and keyboard interactions. It works very well on Windows, Mac as well as Linux. You can install this pa

Create Candlestick Charts For Stocks Using Yahoo Finance

In this article, we will see how to create candlestick chart with historical data for any given symbol using open financial API named Yahoo Finance and Python. We will start by pushing data in a CSV file and then we will use Plotly to create the candlestick chart in Python. Introduction to candlestick chart This is one of the heavily used charts you may have seen multiple times while dealing with stock market dashboards. This is very much used by traders as it provides price movement based on the past patterns. One candle represents 4 points: Open, Close, High, Low as shown below:  In above figure, first candle is filled which depicts that open price was higher than close price. Similarly, second candle depicts that close price was higher than open price. Here do not focus on the color of candle as it can be configured based on your favorite color, based on the dashboard you are using.  In general,  bullish candlestick (close price > open price) is represented by green color and bea

Implementing Dependency Injection In Azure Functions

This article talks about how we can use dependency injection in Azure Functions. Dependency injection is a very well known design pattern that is used to implement IoC as provides you a facility to segregate object creation logic from its usage.  Prerequisites And Tools Used In order to implement dependency injection in Azure Function App, you need an active Azure subscription, Visual Studio (I’m using Visual Studio 2019), and working knowledge of the C# language.  Create Function App in Visual Studio The first step is to create a new project in Visual Studio of type Azure Functions: and select Http Trigger as shown below:  Add Classes For Dependency Injection Next, we need to add the service (classes) which we want to inject. For simplicity, we will create an interface and a class implementing that interface. This interface will have only one method named GetCurrentTime() and it will provide current time to the caller. Here are the definitions: public interface ICurrentTimeProvider {
