In pandas, how can I reset index without adding a new column?
dataframe, pandas, python
Solution
You can use the `drop=True` option in `reset_index()`. See here.
Problem
``` In [37]: df = pd.DataFrame([[1, 2, 3, 4], [2, 3, 4, 5], [3, 4, 5, 6]]) In [38]: df2 = pd.concat([df, df]) In [39]: df2.reset_index() Out[39]: index 0 1 2 3 0 0 1 2 3 4 1 1 2 3 4 5 2 2 3 4 5 6 3 0 1 2 3 4 4 1 2 3 4 5 5 2 3 4 5 6 ``` How can I `reset_index` without adding a new column `index`?
