pandas 常用的数学统计方法 idxmax()
1、定义:计算能够获取到最大值的索引位置(整数)。
2、示例:
import pandas as pd import numpy as np student_info =
pd.read_csv("F:/人工智能/科学计算库/files/student_info.csv") print(student_info)
print("===========================") # idxmax() 计算能够获取到最大值的索引位置(整数)
print(student_info.idxmax()) print("===========================")
np.where(student_info["Math"]==student_info["Math"].max()) # 运行结果: Chinese Math
English 0 88 11.0 22.0 1 33 NaN 30.0 2 85 32.0 90.0 3 45 39.0 NaN 4 11 100.0
103.0 5 88
