python pandas：在iat / iloc和at / loc索引之间进行转换/转换

Question

我在数据框中具有iloc索引，并希望获取相应的loc索引。换句话说：我想要一个函数ilocIndex_to_locIndex将ilocIndex转换为locIndex

df = pd.DataFrame({1 : [1,2,3,4], 2 : [5,6,7,8]})
df = df.drop([1])
iatIndex = 2

df.iloc[ilocIndex]
locIndex = df.ilocIndex_to_locIndex(ilocIndex)
df.loc[locIndex]

Answer 1

您可以为.index下标：

>>> df.index[2]
