要仅显示 DataFrame 中的列名称，请使用 dataframe.columns。
使用别名导入所需的库 -
import pandas as pd;
以下是数据帧 -
dataFrame = pd.DataFrame(
{
"Car": ['BMW', 'Audi', 'BMW', 'Lexus', 'Tesla', 'Lexus', 'Mustang'],"Place": ['Delhi','Bangalore','Hyderabad','Chandigarh','Pune', 'Mumbai', 'Jaipur'],"Units": [100, 150, 50, 110, 90, 120, 80]
}
)示例
使用 dataframe.columns 显示列名。以下是完整的代码 -
import pandas as pd;
# 创建一个数据框
dataFrame = pd.DataFrame(
{
"Car": ['BMW', 'Audi', 'BMW', 'Lexus', 'Tesla', 'Lexus', 'Mustang'],"Place": ['Delhi','Bangalore','Hyderabad','Chandigarh','Pune', 'Mumbai', 'Jaipur'],"Units": [100, 150, 50, 110, 90, 120, 80]
}
)
print"DataFrame ...\n",dataFrame
# 获取所有列名
print"\n Display all the column names ...\n",dataFrame.columns输出结果这将产生以下输出 -
DataFrame ... Car Place Units 0 BMW Delhi 100 1 Audi Bangalore 150 2 BMW Hyderabad 50 3 Lexus Chandigarh 110 4 Tesla Pune 90 5 Lexus Mumbai 120 6 Mustang Jaipur 80 Display all the column names ... Index([u'Car', u'Place', u'Units'], dtype='object')
