Steve Lohr of The New York Times said: “Data scientists, according to interviews and expert estimates, spend 50 percent to 80 percent of their time mired in the mundane labor of collecting and preparing unruly digital data, before it can be explored for useful nuggets.”

Can you automate Excel with Python?

You can write Excel formulas through Python the same way you’d write in an Excel sheet. For example, let’s say we wish to sum the data in cells B5 and B6 and show it on cell B7 with the currency style. That’s pretty simple, right? We can repeat that from column B to G or use a for loop to automate it.
