在Python中对我的字符串的内容重新排序

Question

这是我为了更好地理解而制作的示例数据帧

import pandas as pd

import numpy as np

df = pd.DataFrame([["{postal2:express}", "{postal1:regular}", "{postal4:slow}", "{postal3:slow}","{address1:ABC}","{address4:VPN}","{address3:XYZ}","{address2:POL}"],["{postal1:regular}","{postal4:slow}","{address4:VPN}","{address3:XYZ}","{postal3:slow}","{address1:ABC}","{postal2:express}","{address2:POL}"]], columns=['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'])

但是，我需要的输出应该像图中那样分组： targetdf
