Hello everyone! Today, we’ll talk about how we can use List Comprehension in Python. List Comprehension is generally a syntactic sugar to make code easier to read and write. Often, when we deal with code involving creating lists, it is cumbersome to write nested loops again and again. Python has made this easier for us […]
Today, we’ll be looking at using the Python locals() function. This is yet another utility function which is quite useful for debugging your program. The locals() function gives us the current local symbol table, as a dictionary. Now, if you’re unsure as to what exactly a local symbol table is, keep reading. Let’s go step
Hello again! In today’s article, we’ll be looking at the Python getattr() function in Python. This function tries to get the attribute of a Python object. This is very similar to the setattr() function, but it does not modify the object. Let’s find out how we can put this function to use, using some simple
Hello again! As a part of our Tkinter tutorial series, today’s post will cover the TreeView widget. The TreeView widget is very useful if you want to display a hierarchy of items, with all attributes listed side by side. For example, if you want to construct an application which looks like the Windows File Explorer,
In this article, we’ll take a look at using the Python iter() function. Often, we may want to use iterators, which is an object which itself loads Python objects. But, as opposed to an array or a list, an iterator simply loads objects only as and when required. This is called lazy-loading, or stream-based loading.
Hello everyone! In this post, we’ll look at how we can wait for a specific time in Python. This is particularly important when you have certain events or tasks scheduled after a specific period of time. Python offers us different ways to do this. So let’s look at all the approaches that we can use:
Hello everyone! In today’s post, we’ll be doing something exciting – building a KeyLogger in Python! Have you ever wanted to monitor your keyboard and look at the your typing history and analyze how you type? Well, the starting step is to build a keyboard monitoring tool – or a KeyLogger! While you may very
In this article, we’ll take a look at using the Python itertools Module. This module is very useful if you want to create different types of iterators suitable for various tasks. If you’re able to learn some of the methods of this module, this could be a very useful addition to your toolbox! Let’s get
Hello everyone! In today’s article on Tkinter, we’ll cover the Tkinter Button widget. The Tkinter button widget is a very simple and easy-to-use widget. Let’s look at how we can construct buttons and add functionality to our GUI application, using some illustrative examples! Tkinter Button Widget This widget can be used to make different types
Raw strings in Python are a useful yet underutilized feature. They allow you to define string literals that completely ignore escape sequences and treat backslashes literally. This enables you to easily define strings with newlines, quote characters and other special characters that would otherwise require cumbersome escaping. Raw strings make the source code more readable
