A population pyramid is a graphical representation of the age and gender distribution of a population. It consists of two back−to−back bar charts, one showing the distribution of males and the other showing the distribution of females across different age groups. The population pyramid is a powerful visualisation tool that can help us understand the demographic composition of a population and identify trends and patterns. In this article, we will explore how to create a population pyramid using Plotly in Python. Plotly is a powerful visualisation library that allows us to create interactive and dynamic plots in Python. We will ... Read More
When working with data in Python, there may be situations where you need to organise your data into a list of N−lists.

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
