将二进制编码转换为类multilabel python

问题描述

我在数据框中有这样的数据

I have data like this in dataframe

你好，我叫约翰

1

0

1

0

我想基于1和0填充标签列，就像这样

and I want to fill the labels column based on the ones and zeros to be like this

你好，我叫约翰

['Label1'，'Label3']

我该如何在python中做什么?

How can I do in python?

推荐答案

好，这是来自此答案的未经测试的建议.尝试收集适当的列标签，然后在适当的函数上使用DataFrame.apply:

Ok, this is an untested suggestion from this answer. Try gathering the appropriate column labels then using DataFrame.apply on a suitable function:

test_cols = [c for c in df.columns if c[:5].lower() == 'label']
test_cols.remove('Labels')

def aggLabels(aSeries):
    return [lab for lab in test_cols if aSeries[lab]==1]

df['Labels'] = df.apply(aggLabels, axis=1)

正如我所说，这是未经检验的；可能需要进行代码调整.

As I say this is untested; there may be code tweaks required.
