It is a common and routine task in Python; the act of writing binary data to a file when you need to save non-textual data such as images, audio files, or serialized objects. In this article, we will explore various ways how you can write binary data to a file using Python and provide you with code examples followed by comprehensive explanations to help you grasp the concept. To write binary data to a file in Python, you can follow these steps: Open the File in Binary Mode First, you should proceed to open the file in ... Read More
The current working directory in Python is defined as the directory from where the Python script is being executed. By default, the current working directory is usually the directory where the script is stored, located or resides. However, there may arise scenarios or instances where you may want to change the current working directory using Python code. In this article, we will explore various methods to set the current working directory in Python. To this end, will take up several code examples and their explanations to elucidate the process of setting the current working directory programmatically. Making Use of ... Read More
The creation and modification datetime of a file in Python are defined as the timestamps associated with the events of when the file was created and when it was last modified. Creation datetime: It is defined as the timestamp when a file was initially created or added to the file system. Modification datetime: It is defined as the timestamp when the file's content was last modified or updated. These datetimes can provide a lot of information such as the file's age, recent changes, or when it was first introduced. In Python, you can fetch the ... Read More
The act of renaming multiple files recursively in Python can be a useful task when it is required to change the names of multiple files within a directory and its subdirectories. If you need to replace certain characters, add prefixes or suffixes, or completely change the file names, Python has powerful tools to accomplish such operations. In this article, we explore a few different approaches to renaming multiple files recursively using Python. We consider some code examples, each demonstrating a unique method to achieve this task. So let us get started right away and learn how to rename multiple files ... Read More
Plotting random points under a sine curve is a fascinating visual exercise that demonstrates the versatility of Matplotlib in Python. By generating random points and offsetting them along the y-axis, we can create a scatter plot that appears to follow the shape of a sine wave. This article delves into the process of generating these random points, calculating their corresponding y-coordinates using the sine function, and visualizing the results using Matplotlib. We'll gain a deeper understanding of how to leverage Matplotlib's plotting capabilities to create engaging and dynamic visualizations. How to plot random points under a sine curve in ... Read More
