Getting Substring after certain char in python

Question

I want to cut a String such as "0011165.jpg_Fish" to get only Fish, so everything after the "_", how do i do that in python?

Thank you very much!

how do i use this on a whole dataframe? like train['Label'] = train.Image_Label.split("_")[1] ? — Sven Prüß, Aug 28 '19 at 12:34
`train['Label'] = train.Image_Labels.str.split("_").str[1] ` — Rakesh, Aug 28 '19 at 12:35

Please use str.partition instead of str.split. This is robust, since you can always expect 3 items, unlike, split which maybe tricky to handle if the input string doesn't have the split character,

>>> word = '0011165.jpg_Fish'
>>> not_required, split_char, required = word.partition('_')
>>> required
'Fish'

Try

"0011165.jpg_Fish".split("_")[1]

And in case of a Dataframe

train['Label'] = train.Image_Labels.str.split("_").str[1]
