KeyError: 'labels [data] not contained in axis'

Question

我尝试了几种不同的方法来向现有的 Pandas 数据框添加一行。例如，我尝试了解决方案 here。但是我无法纠正这个问题。我已经恢复到原来的代码，希望有人能在这里帮助我。

这是我的代码：

print('XDF Created, Starting Bucket Separation...')
XDFDFdrop = pd.DataFrame.duplicated(XDFDF,subset='LastSurveyMachineID')
index_of_unique = XDFDF.drop_duplicates(subset='LastSurveyMachineID')
for index,row in zip(XDFDFdrop,XDFDF.itertuples()):
    if index:
        goodBucket.append(row)
    else:
        badBucket.append(row)
goodBucketDF = pd.DataFrame(goodBucket)
badBucketDF = pd.DataFrame(badBucket)

print('Bucket Separation Complete, EmailPrefix to F+L Test Starting...')
for emp , fname , lname , row1 in zip(goodBucketDF['EmailPrefix'] , goodBucketDF['Fname'] , goodBucketDF['Lname'] , goodBucketDF.itertuples()):
    for emp2 , row2 in zip(goodBucketDF['EmailPrefix'] , goodBucketDF.itertuples()):
        if columns != rows:
            temp = fuzz.token_sort_ratio((fname+lname),emp)
            temp2 = fuzz.token_sort_ratio((fname+lname),emp2)
            if abs(temp - temp2) < 10:
                badBucketDF.append(list(row2))
                goodBucketDF = goodBucketDF.drop(row2)
                removed = True
        rows += 1
    if removed:
        badBucketDF.append(list(row2))
        goodBucketDF = goodBucketDF.drop(row2)
        removed = False
    columns += 1

请注意：XDFDF 是一个相对较大的数据集，它是使用 pandas 构建的，并且是从数据库中提取的（它不应该影响您看到的代码，我想我会公开该信息）。

这是我的错误：

Traceback (most recent call last):
  File "/Users/john/PycharmProjects/Greatness/venv/Recipes.py", line 122, in <module>
    goodBucketDF = goodBucketDF.drop([rows])

进程已完成，退出代码为 1

我想知道是否有人对此错误有解决方案，以便：我可以从一个 DataFrame 添加一行，将其放在另一个 DataFrame 中（不需要按顺序排列，我不关心索引是否重复）。一旦它在新的 Dataframe 中，我想将它从旧的 DataFrame 中删除。

我当前的问题是从旧 Dataframe 中删除该行。任何帮助，将不胜感激。

如果您对代码有任何疑问，请告诉我，我会尽快回复。谢谢您的帮助。

下面我包含了第 1 行的打印输出。希望这也会有所帮助。

Pandas(Index=1, _1=2, entity_id='1180722688', email='assassin_penguin@live.com', Fname='jim', Lname='smith', Birthdate='1990-09-14', EmailPrefix='assassin_penguin', LastSurveyMachineID=None)

Answer 1

鉴于 XDFDF 是 pandas.DataFrame，下面的工作不应该吗？

XDFDFdrop = pd.DataFrame.duplicated(XDFDF,subset='LastSurveyMachineID')
goodBucket = XDFDF.loc[~XDFDFdrop] #the ~ negates a boolean array
badBucket = XDFDF.loc[XDFDFdrop]

编辑：

更新的错误来自于您将整行而不是索引传递给函数 pandas.DataFrame.drop。

KeyError: 'labels [data] not contained in axis'
