Question

我有两个数据框，我使用的Excel有三张纸。 SQL / Bio / Gen。在Bio和Gen中，IDs (Labornumber) 191****** and 192******是两种不同的类型。这两个框架都有SQL工作表中的布局。

Data2应该仅包含192个数字，而data1应该具有191个数字。对于data2，所有192个数字都在SQL工作表中。在gen中有191和192的数字，所以我用

对其进行过滤

regex = re.compile(r"(?!191\d*)")

for index, row in self.data1.iterrows():
    if(re.match(regex, str(row["Labornummer"]))):
        self.data1.drop(index, inplace=True)

这很好用，我的data1数据框中有全部191个。之后，我将{1}}

与data1和我从gen和bio获得的所有信息合并

data2相同，但我将其与条形码/系统样本ID合并

那行得通，每一帧都有我需要更改其单元格的所有数据。

有问题的Data1有7387行和96列。我遍历每一行并保存以后要更改的索引。这样做工作正常，但是如果我想使用保存在列表中的索引来更改特定单元格中的值，则会收到错误Labnumber

我以后要更改的保存索引的功能：

KeyError: 6817

用于更改特定单元格中的值的函数：

for index, row in self.data1.iterrows():
        if row["Diagnosis"] == "Disease":
            if self.getCutOffResult(row["Result"], row["Diagnosis"]):
                b_Disease_pos_1.append(index)

两个函数都更改了data1和data2，但仅data1仅对data2没问题，而从我的角度来看data1应该没有问题，因为索引存在，我在dataframe和excel中都看到了我用大熊猫出口。我遍历每一行，所以它必须存在。

数据框：

for index in container:   
                    if self.isSecondRequest(index):
                        self.data1.at[index, row] = 2
                    else:
                        self.data1.at[index, row] = 1

熊猫数据框df.at KeyError
