Pandas11——excel重复数据

excel数据示例

要求：

1、以Name为参考，去除重复项
2、以Name为参考，输出重复项

import pandas as pd

employee=pd.read_excel("D:\\python_pandas\\sample\\demo13\\Students_Duplicates.xlsx")
table = employee.drop_duplicates(subset="Name",ignore_index=True)
print(table.head(30))
print("*"*40)
condition=employee.duplicated(subset="Name")
print(employee[condition])

输出结果：
