Python - 查找 Pandas DataFrame 的统计信息摘要
要查找DataFrame的统计信息摘要，请使用describe()方法。首先，我们导入了以下带有别名的pandas库
import pandas as pd
以下是我们的CSV文件，我们正在创建一个PandasDataFrame-
dataFrame = pd.read_csv("C:\\Users\\amit_\\Desktop\\CarRecords.csv")现在，获取我们的PandasDataFrame的统计摘要-
dataFrame.describe()
示例
以下是完整代码
import pandas as pd
#读取csv文件
dataFrame = pd.read_csv("C:\\Users\\amit_\\Desktop\\CarRecords.csv")
print("DataFrame...\n",dataFrame)
#计算DataFrame中的行和列
print("\nNumber of rows and column in our DataFrame = ",dataFrame.shape)
#数据框摘要
print("\nGet the summary of statistics of a DataFrame = \n",dataFrame.describe())
#返回前7行记录
print("\nDataFrame with specific number of rows...\n",dataFrame.head(7))输出结果这将产生以下输出
