pandas Common mathematical statistical methods idxmax()
1, definition ： Calculate the index position that can get the maximum value （ integer ）.
2, Examples ：
import pandas as pd import numpy as np student_info =
pd.read_csv("F:/ artificial intelligence / Scientific Computing Library /files/student_info.csv") print(student_info)
print("===========================") # idxmax() Calculate the index position that can get the maximum value （ integer ）
print(student_info.idxmax()) print("===========================")
np.where(student_info["Math"]==student_info["Math"].max()) # Running results ： Chinese Math
