编写 Python 代码以重命名数据框中的给定轴
假设您有一个数据框，重命名轴的结果是，
Renameindex: index Id Age Mark 0 1.0 12.0 80.0 1 2.0 12.0 90.0 2 3.0 14.0 NaN 3 NaN 13.0 95.0 4 5.0 NaN 85.0
解决方案
为了解决这个问题，我们将按照下面给出的步骤-
定义数据框
将轴名称内的函数应用为“索引”并设置轴=1df.rename_axis()
df.rename_axis('index',axis=1)例子
import pandas as pd
df = pd.DataFrame({"Id":[1, 2, 3, None, 5],
"Age":[12, 12, 14, 13, None],
"Mark":[80, 90, None, 95, 85],
})
print("Dataframe is:\n",df)
print("Renameindex:")
df = df.rename_axis('index',axis=1)
print(df)输出
Dataframe is: Id Age Mark 0 1.0 12.0 80.0 1 2.0 12.0 90.0 2 3.0 14.0 NaN 3 NaN 13.0 95.0 4 5.0 NaN 85.0 Renameindex: index Id Age Mark 0 1.0 12.0 80.0 1 2.0 12.0 90.0 2 3.0 14.0 NaN 3 NaN 13.0 95.0 4 5.0 NaN 85.0
