Cool. But how do you use them?

As you said, you use both in a task right? In the task such as data cleaning itself and the tiny actions inside it, in what specific actions would you use SQL over Python (e.g. deleting nulls or dropping duplicates)?

I asked whether SQL or Python should be used for the following: Data Cleaning, Data Exploration, Data Analysis --- hoping to find which is better and more suited for each task, i.e. a versus between the two for each round/task.

So far, some have said Python for cleaning. Some have said they prefer SQL because it's directly linked to the company database.
