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')]

unique = set(a) result = [] for i in unique: if i[0] != '': result.append(i[0]) if i[1] != '': result.append(i[1]) if i[2] != '': result.append(i[2])

result = [x for x in result if x != ''] result = ','.join(result) print(result) # 输出为1,se_area,pid
