Pandas 读取 .csv 并设置索引列

Question

I have a problem when I read a .csv and set the 'Column A' as index column.

df = pd.read_csv(index_col = 'Column A')
print(df.colums)

However, I cannot access 'Column A' anymore. I still want to use it as one column to access its date.

Can anyone help?

Answer 1

我发现这非常简单：只需将索引设置为列。

df['index1'] = df.index

Answer 2

这将起到作用，简单而干净：

df = pd.read_csv().set_index('Column A')
