python a = pid pid se_area se_area se_area se_area se_area pid pid se_area se_area se_area 1 1去重并组合到一起变成1se_areapid 这个的很简单的完整代码错误输出为pid1se_area

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

result = set() for item in a: if item[0] != '': result.add(item[0]) if item[1] != '': result.add(item[1]) if item[2] != '': result.add(item[2])

result_list = list(result) result_list.sort()

print(','.join(result_list)) # 输出为1,pid,se_area
