从解析的CSV数组中删除重复项

import csv

def remove_duplicates_from_csv(csv_data):
    unique_data = []
    seen_elements = set()

    for row in csv_data:
        # 将CSV行转换为字符串，以便比较
        row_str = ','.join(row)

        if row_str not in seen_elements:
            unique_data.append(row)
            seen_elements.add(row_str)

    return unique_data

# 假设csv_data是解析的CSV数组
csv_data = [
    ['1', 'John', 'Doe'],
    ['2', 'Jane', 'Smith'],
    ['1', 'John', 'Doe'],  # 重复项
    ['3', 'Bob', 'Johnson']
]

unique_data = remove_duplicates_from_csv(csv_data)
print(unique_data)
