How to reset index in a pandas dataframe?
dataframe, indexing, pandas, python
Solution
`DataFrame.reset_index` is what you're looking for. If you don't want it saved as a column, then do:
df = df.reset_index(drop=True)
If you don't want to reassign:
df.reset_index(drop=True, inplace=True)
Problem
I have a dataframe from which I remove some rows. As a result, I get a dataframe in which index is something like `[1,5,6,10,11]` and I would like to reset it to `[0,1,2,3,4]`. How can I do it? The following seems to work: ``` df = df.reset_index() del df['index'] ``` The following does not work: ``` df = df.reindex() ```
