How can I split a list of comma separated words in a Pandas column?
Question
I was querying Stackoverflow to get some data ( https://data.stackexchange.com/stackoverflow/query/new ), and I have a data frame with Tags as a column. The tags originally were of the form
<html><css>
I managed to get them in the form of
html,css
I think an image of my Jupyter notebook can display it best:
How can I separate the tags so that they can become categorical variables, and I can transform them using something like get_dummies? Everything I've seen refers to actual lists, like [html,css], rather than just comma separated words.

为此，我们可以使用df['Tags'].str.get_dummies(',') ，该方法基本上执行split并将每个元素转换为自己的一键编码列。
