select 数据框中的行不在具有不同形状数组且对象不可迭代的不同数据框中
select rows in dataframe not in different dataframe with different shape arrays and where object is not iterable
我正在尝试 select 数据帧中不与临时数据帧共享 uniqueID 的行，但是当我使用以下命令时
NotProcessed= FileListDF.loc[FileListDF['DocID'] != InterimDF.DocID.tolist()] 我明白
ValueError: Arrays were different lengths: 255 vs 246
当我期望一个包含 9 行的数据框在 FileListDF 中但不在 InterimDF 中时
这个 似乎遇到了类似的问题，但答案不明确，当我尝试时，我得到
'UUID' object is not iterable
我不确定它是否连接到我使用 uuid.uuid4() 在第一个实例中创建 DocID
示例数据
FileListDF..to_json

所以如果我理解正确的话，你有两个数据框，每个数据框都有一列，两者之间有一些重叠。
为简单起见，我将它们称为 df_one 和 df_two，它们都有一个 id 列。
您可以使用 isin() 过滤掉重叠部分，或者反过来过滤掉重叠部分。
例如
import pandas as pd
df_one = pd.DataFrame(data={'id':[1,2,3,4,5]})
df_two = pd.DataFrame(data={'id':[3,4,5,6,7]})
new_ids = ~df_one['id'].isin(df_two['id'])
df_only_in_one = df_one[new_ids]
我正在尝试 select 数据帧中不与临时数据帧共享 uniqueID 的行，但是当我使用以下命令时
NotProcessed= FileListDF.loc[FileListDF['DocID'] != InterimDF.DocID.tolist()] 我明白
ValueError: Arrays were different lengths: 255 vs 246
当我期望一个包含 9 行的数据框在 FileListDF 中但不在 InterimDF 中时
这个
'UUID' object is not iterable
我不确定它是否连接到我使用 uuid.uuid4() 在第一个实例中创建 DocID
示例数据

所以如果我理解正确的话，你有两个数据框，每个数据框都有一列，两者之间有一些重叠。
为简单起见，我将它们称为 df_one 和 df_two，它们都有一个 id 列。
您可以使用 isin() 过滤掉重叠部分，或者反过来过滤掉重叠部分。
例如
import pandas as pd
df_one = pd.DataFrame(data={'id':[1,2,3,4,5]})
df_two = pd.DataFrame(data={'id':[3,4,5,6,7]})
new_ids = ~df_one['id'].isin(df_two['id'])
df_only_in_one = df_one[new_ids]
