Python 列表去重并组合 - 完整代码示例

a = [('pid', '', ''), ('pid', '', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('pid', '', ''), ('pid', '', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('', 'se_area', ''), ('', '', '1'), ('', '', '1')]

unique_a = set(a) # 去重 result = [] for tup in unique_a: result.extend([item for item in tup if item]) # 组合

print(','.join(result)) # 输出：1,se_area,pid
