如何使用python从矩阵中删除相同的列表

matrix = [[1, 2], [3, 4], [1, 2], [5, 6]]

# 将列表转换为元组的集合以去除重复项
unique_tuples = set(tuple(row) for row in matrix)

# 将元组转换回列表
unique_matrix = [list(tup) for tup in unique_tuples]

print(unique_matrix)

matrix = [[1, 2], [3, 4], [1, 2], [5, 6]]

def is_duplicate(row, seen):
    return any(row == x for x in seen)

unique_matrix = []
seen = set()
for row in matrix:
    if not is_duplicate(row, unique_matrix):
        unique_matrix.append(row)
        seen.add(tuple(row))

print(unique_matrix)

import pandas as pd

matrix = [[1, 2], [3, 4], [1, 2], [5, 6]]
df = pd.DataFrame(matrix)

# 使用drop_duplicates方法去除重复行
unique_df = df.drop_duplicates().values.tolist()

print(unique_df)
