pandas -删除MultiIndex DataFrame中的重复行

import pandas as pd

# 创建一个MultiIndex DataFrame
data = {'A': [1, 1, 2, 2, 3, 3],
        'B': [4, 4, 5, 5, 6, 6]}
index = pd.MultiIndex.from_tuples([('a', 'x'), ('a', 'y'), ('b', 'x'), ('b', 'y'), ('c', 'x'), ('c', 'y')])
df = pd.DataFrame(data, index=index)

# 打印原始的MultiIndex DataFrame
print("原始的MultiIndex DataFrame:")
print(df)

# 删除重复行
df = df.drop_duplicates()

# 打印删除重复行后的MultiIndex DataFrame
print("删除重复行后的MultiIndex DataFrame:")
print(df)

原始的MultiIndex DataFrame:
     A  B
a x  1  4
  y  1  4
b x  2  5
  y  2  5
c x  3  6
  y  3  6
删除重复行后的MultiIndex DataFrame:
     A  B
a x  1  4
b x  2  5
c x  3  6
