is excel is needed when one knows python?

Hi Aditya,

Excel will be needed even if you're a python specialist, yes. Here are a few reasons why you might need Excel when you can work with Python:

1. In certain situations it'll be more convenient to use a spreadsheet tool to visualize a multi-layered calculation
2. You might be faster in Excel, if the operations are fairly simple
3. Many, many people know how to work with Excel and few are able to use Python, so if you have to collaborate, you'll probably have to do it in Excel
4. Excel offers some interesting functionalities for data manipulation and data cleaning, which shouldn't be neglected
5. Excel slicers and pivot tables are a great tool
6. Data visualization can be easier in Excel

Of course, there are many counter-arguments why you should stick to Python. But in general, yes, you'll need Excel and you'll do great to learn it.
Best,
Ned
