我有一个简单的数据集.
I have a simple dataset.
id,question,category,tags,day,quarter,group_id
1,What is your name,Introduction,Introduction,1,3,0
2,What is your name,Introduction,"Introduction, work",1,3,1
现在,如果您看到,在 tags
列中有多个用逗号分隔的输入.如果我尝试使用 pandas get_dummies
函数进行一次热编码,我会将其作为单列获取.但我想为每个标签创建列.我怎么可能做到这一点?
Now if you see, in the tags
column there are multiple inputs seperated by commas. If I try to one-hot-encode using pandas get_dummies
function I will get that as a single column. But I wanted to create columns for each tags. How can I do that possibly?
相信需要str.get_dummies
:
df1 = df['tags'].str.get_dummies(', ')
print (df1)
Introduction work
0 1 0
1 1 1
这篇关于列中具有多个标签的一种热编码的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
