In pandas, how can I reset index without adding a new column?
提问by waitingkuo
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
My problem is that how can I reset_indexwithout adding a new column index?
我的问题是我怎么能reset_index不添加新列index?
