如何在 python 中的 Dataframe 中创建新的自动增量列

Question

I have a basic question in python

How to create Index Column with Auto Increment with 1 which is similar to X=X+1

Data['Index'] = Data['Index'] + 1 --> This line didn't worked for me 

Answer 1

It's not entirely clear what you're trying to do. If you want to have a new index auto-incrementing from 1:

df["new_index"] = df.index + 1

should work.

I think the problem you may have had is calling your new column by the same name you are incrementing.
