Excel uses a special format to store dates and times, called serial date numbers. Serial date numbers are a count of days since January 1, 1899, which is the date that Excel considers to be the beginning of time. Python's datetime module provides powerful tools for working with dates and times. However, when it comes to interoperability with other applications, such as Microsoft Excel, we often encounter the need to convert Python datetime objects into Excel's serial date number format. In this article, we will explore how to perform this conversion and bridge the gap between Python and Excel. Understanding ... Read More

When working with data in Python, it is often necessary to transform and manipulate arrays to facilitate analysis and computations. One common scenario is converting a 1D array of tuples into a 2D Numpy array. This conversion allows for easier indexing, slicing, and applying array operations. In this article, our focus will be on the conversion process of transforming a 1D array of tuples into a Numpy array. 1D Array of Tuple A 1D array of tuples refers to a data structure in which tuples are arranged sequentially in a one−dimensional array. For example, consider the following 1D array of ... Read More

SQLite is a popular, lightweight, and self−contained database engine that is widely used in various applications. One of the unique features of SQLite is its ability to create databases in memory, which allows for faster data access and manipulation. In this article, we will explore how to connect to an in−memory SQLite database using Python, providing step−by−step instructions, code examples, explanations, and sample outputs. Understanding SQLite In−Memory Databases An SQLite in−memory database is a temporary database that resides entirely in memory instead of being stored on disk. This type of database is useful for scenarios where data needs to be ... Read More

Pandas is a powerful data manipulation library widely used in Python for data analysis and preprocessing tasks. When working with data, it is common to encounter situations where dates and times are represented as floating−point numbers instead of the expected datetime format. In such cases, it becomes essential to convert the float values to datetime objects to perform accurate time−based analysis. This article aims to provide a comprehensive guide on how to convert float values to datetime objects in a Pandas DataFrame. Understanding the importance of converting float to datetime Datetime objects offer several advantages over float representations of dates ... Read More

JSON (JavaScript Object Notation) is a popular format for data exchange between systems. It is a lightweight, text−based, and easy−to−parse format that has become a standard for data exchange over the internet. However, JSON does not provide any order for the elements in the data structure. While this may not be an issue in most cases, there are situations where the order of the elements is important. On the other hand, OrderedDict is a subclass of the built−in dict class in Python, which maintains the order of the keys in the dictionary. The order is determined by the order in ... Read More
