从可编辑的 pdf 解析后如何仅旋转 python 数据框中的特定列

Question

我正在尝试创建一个过程，通过可编辑的 pdf 上传某些可编辑的 pdf 数据解析，然后将数据排列在 df 中。我已经设法读取可编辑 pdf 中的数据并将它们放入 df 中，但我遇到了一个问题，其中个人的姓名在 df 中显示为列，而不是每个玩家的单独行，目前的行为每个玩家都以 name_# 的形式出现 ,位置_#,国家_#..

这不是我使用的实际数据，只是重新创建我面临的场景。

df = pd.DataFrame({'Team': ["Bayern", "Barcelona", "Madrid"],                   
               'region': ["Bravaria","Barcelona", "Madrid"],
                'title': ["Bundesliga","Laliga", "Champions Leauge"],
               'name_1': ["Robben","Messi", "Ronaldo"],
               'Position_1': ["RW","ST", "ST"],
               'Country_1': ["Netherlands","Argentina", "Portugal"],
               'name_2': ["Ribery","Neymar", "Benzema"],
               'Position_2': ["LW","LW", "RW"],
               'Country_2': ["FRANCE","Brazil", "France"]})

df

我正在尝试找到一种方法来重新定位 DF，以便它可以看起来下面共享的 df： 每个团队都有不同的 pdf，但结构都是相同的。任何想法都会有帮助。谢谢

df1 = pd.DataFrame({'Team': ["Bayern", "Barcelona", "Madrid", "Barcelona", "Madrid","Bayern"],                   
               'region': ["Bravaria","Barcelona", "Madrid", "Barcelona", "Madrid","Bravaria"],
                'title': ["Bundesliga","Laliga", "Champions Leauge","Laliga", "Champions Leauge","Bundesliga"],
               'name': ["Robben","Messi", "Ronaldo","Neymar","Benzema","Ribery"],
               'Position': ["RW","ST", "ST", "ST","RW","LW"],
               'Country': ["Netherlands","Argentina", "Portugal","Brazil","France","France"]
               }
              
              )

df1

Answer 1

尝试：

df["name"] = df.filter(regex=r"name_\d+").agg(list, axis=1)
df["country"] = df.filter(regex=r"Country_\d+").agg(list, axis=1)
df["position"] = df.filter(regex=r"Position_\d+").agg(list, axis=1)

print(
    df.explode(["name", "country", "position"])[
        ["Team", "region", "title", "name", "position", "country"]
    ]
)

打印：

        Team     region             title     name position      country
0     Bayern   Bravaria        Bundesliga   Robben       RW  Netherlands
0     Bayern   Bravaria        Bundesliga   Ribery       LW       FRANCE
1  Barcelona  Barcelona            Laliga    Messi       ST    Argentina
1  Barcelona  Barcelona            Laliga   Neymar       LW       Brazil
2     Madrid     Madrid  Champions Leauge  Ronaldo       ST     Portugal
2     Madrid     Madrid  Champions Leauge  Benzema       RW       France
