当我的列 header 的名称中有 \ 时，如何将 dataframe 拆分为多个列？

Question

I have a dataframe called ratings. It is a single column, named "tconst\taverageRating\tnumVotes", although it needs to be split into 3, separated by "\".

I understand that this statement can be used: ratings[['tconst','taverageRating','tnumVotes']] = ratings.???.str.split("\",expand=True,)

However, when I replace??? with the actual column name, I get an error. I believe this is because of the \s in the column header.

Any help would be greatly appreciated.

Answer 1

Are you sure you are reading the data in correctly? Looking at the header names, it looks likely that your data is actually \t ie tab separated (so, \t and numVotes make sense separately). In that case you should read your data like this:

pd.read_csv('http://language.media.mit.edu/data/public/unesco_langlang_20120722_iso639-3.txt', sep='\t')
