IntroductionBeing a programmer it is essential to learn to use databases in our applications to store, retrieve, manipulate, and delete data with ease. Python comes with the SQLite package preinstalled with it, using which we can create and manipulate SQLite databases.SQLite databases are written in a single file and are hence are easier to use and access. You can easily manipulate the data within and hence is very easy for data analysis. It is very simple and easy to setup and use.Getting StartedNow that you know, what SQLite is and why we use it, let us get started with how ... Read More

The flower dataset can be visualized with the help of the ‘matplotlib’ library. The ‘imshow’ method is used to display the image on the console. The entire dataset is iterated over, and only the first few images are displayed.Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks?We will be using the flowers dataset, which contains images of several thousands of flowers. It contains 5 sub-directories, and there is one sub-directory for every class.  We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the ... Read More

The flower dataset can be downloaded using a google API that basically links to the flower dataset. The ‘get_file’ method can be used to pass the API as a parameter. Once this is done, the data gets downloaded into the environment.Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks?We will be using the flowers dataset, which contains images of several thousands of flowers.

IntroductionIn Python, we use the tkinter library to create GUI components and craft better user interface.In this article you will learn methods to build a simple GUI based calculator application.Getting startedBefore we jump into it, there are a few things we need to get organised first.Let us start by downloading Python’s imaging library that we will be using to get images from our local system. In order to install PIL(Pillow), launch you terminal and type the command below.pip install PillowNow that you have the package installed. You will have to download icons needed for the calculator.You can go on Google ... Read More

IntroductionThe time library in Python is used to obtain time in the real world and perform various tasks related to it. You can even manipulate execution time using this module.Getting StartedThe time module comes packaged with Python. This means you do not have to install it separately using the PIP package manager.In order to use its various functions and methods, you must first import it.import timePrinting current local timeIn order to print the current local time, we will be using the ctime() function.But firstly, we must obtain the number of seconds since epoch. That is, the number of seconds since ... Read More

IntroductionThe pydoc module automatically generates documentation from Python modules. The documentation can be saved as pages of text on the console, displayed on the web browser, or even as HTML files.In this article you will be learning methods to view these documentations in various cases and even learn about docstrings that help you create your own documentation for your python scripts.Now that you know the use of pydoc, let us get started.Getting StartedThe pydoc module comes packaged along with Python, which means you don’t have to download and install it separately.In order to access pydoc, you can must first import ...
