In Python we have a number of modules and packages which needs to be installed to work with. We have various ways to check if a python package is installed in python environment. Package is a directory which contains one or more python modules and also has the __init__.py file which is an initialization file. For using the package, we have to import it by its name. These can be inbuilt packages or allows developers to create the reusable code that can be imported into other programs by avoiding the duplicating of code. Using try and except When we ...

Pandas is one of the libraries in python which is abbreviated as Python Data Analysis Library. It is used to perform data analysis, data cleaning, data manipulations and scientific calculations. The data in pandas library is represented in columns and rows. It has many functions and modules which are used to perform data analysis and manipulations. Python provides different ways to check if pandas column has ... Read More

Iterable object is the object that can be iterated through all its elements using a loop or an iterable function. The lists, string, dictionary, tuples etc. are all known as iterable objects. There are different ways to check if an object is iterable or not in the Python language. Let’s see them one by one. Using a loop In python, we have two looping techniques, one is using the ‘for’ loop and the other is using the ‘while’ loop. Using any one of these two loops, we can check whether the given object is iterable or not. Example In ... Read More

A program under execution is known as process. A process can be applications running on the current operating system or, applications related to the Operating system. If an application is related to operating system, firstly it will create a process to execute itself. The other applications rely on operating system services for execution. Most of the applications are OS services and the background applications that maintain the operating system, software and Hardware. We have different ways in python to check whether if an application is open or not. Let’s see them one by one in detail. Using ... Read More

Files are used to store certain data based on user requirement. A file can contain any type of information suchas audio, text, images, video or program. Depending on the data present in a file, the size of a file varies. The size of a file is measured in bits or bytes. A bit is the smallest unit of information which is typically represented by a single value: either 0 or 1. Bytes are used to measure the amount of data in a file and the bytes are denoted by 8 bits. There are several ways to check the file ... Read More

While building video games, we often try to setup an image or logo for that developed game. Python provides a function in pygame named, set_icon(), which sets the icon as desired. Pygame is a set of modules that allows us to develop the games and multimedia applications. This is built in top of the SDL(Simple Direct Media Layer) library which has low access to the audio keyboard, mouse, joystick and graphics hardware through OpenGL and Direct3D. Syntax Following is the syntax for setting the icon for the game - pygame_icon = pygame.image_load(“image_name”) pygame.display.set_icon(pygame_icon) Where, pygame_icon is the name ... Read More
