Python - 重命名 Pandas DataFrame 的列
要重命名 DataFrame 的列,请使用rename()方法。在rename()方法的“columns”参数下设置要重命名的列名称。例如,将“ Car ”列更改为“ Car Name ” -
dataFrame.rename(columns={'Car': 'Car Name'}, inplace=False)
首先,读取 CSV 并创建一个 DataFrame -
dataFrame = pd.read_csv("C:\\Users\\amit_\\Desktop\\SalesRecords.csv")
现在,重命名列名。在这里,我们将重命名列“Car”、“Date_of_Purchase”和“Reg_Price” -
dataFrame = dataFrame.rename(columns={'Car': 'Car Name', 'Date_of_Purchase': 'Sold On', 'Reg_Price' : 'Booking Price'}, inplace=False)
示例
以下是代码
import pandas as pd输出结果# reading csv file
dataFrame = pd.read_csv("C:\\Users\\amit_\\Desktop\\SalesRecords.csv")
print("DataFrame...\n",dataFrame)
# count the rows and columns in a DataFrame
print("\nNumber of rows and column in our DataFrame = ",dataFrame.shape)
dataFrame = dataFrame.rename(columns={'Car': 'Car Name', 'Date_of_Purchase': 'Sold On', 'Reg_Price' : 'Booking Price'}, inplace=False)
print("\nDataFrame with updated Column Name ...\n",dataFrame)
这将产生以下输出 -
DataFrame...Car Date_of_Purchase Reg_Price
0 BMW 10/10/2020 1000
1 Lexus 10/12/2020 750
2 Audi 10/17/2020 750
3 Jaguar 10/16/2020 1500
4 Mustang 10/19/2020 1100
5 Lamborghini 10/22/2020 1000
Number of rows and column in our DataFrame = (6, 3)
DataFrame with updated Column Name ...
Car Name Sold On Booking Price
0 BMW 10/10/2020 1000
1 Lexus 10/12/2020 750
2 Audi 10/17/2020 750
3 Jaguar 10/16/2020 1500
4 Mustang 10/19/2020 1100
5 Lamborghini 10/22/2020 1000
