这可以通过在rename()函数中传递一个字典来实现,其中字典的键为原始列名,字典的值为新的列名。 # 重命名列名df=df.rename(columns={'A':'Column1','B':'Column2','C':'Column3'})print("重命名后的数据框:")print(df) 1. 2. 3. 4. 5. 输出结果如下: 重命名后的数据框: Column1 Column2 Col...
Renaming columns in a DataFrame using Python is a simple yet powerful technique that can improve the readability and organization of data. By using therename()method with a mapping of old column names to new column names, we can easily rename columns in a DataFrame. Visualizing the relationships...
