Regex words extraction within a string store it into a python list

Question

I am new to regex, I want to extract specific words within a python string. This is the string:

'1. feature name: occupation_Transport-moving coefficient: 0.1776 2. feature name: education coefficient: 0.0726 3. feature name: occupation_Machine-op-inspct coefficient: 0.0661 4. feature name: occupation_Armed-Forces coefficient: 0.0006 5. feature name: workclass_Without-pay coefficient: -0.0194 6. feature name: occupation_Handlers-cleaners coefficient: -0.1256 7. feature name: occupation_Farming-fishing coefficient: -0.3938 8. feature name: GDP Group coefficient: -0.4138 9. feature name: occupation_Other-service coefficient: -0.4294 10. feature name: occupation_Priv-house-serv coefficient: -0.6560 '

The result I am looking for:

[occupation_Transport-moving,education,occupation_Machine-op-inspct,occupation_Armed-Forces,workclass_Without-pay,occupation_Handlers-cleaners,occupation_Farming-fishing,GDP Group,occupation_Other-service,occupation_Priv-house-serv]

I have tried this but it does return the whole string starting from:: re.findall(':\s(.*)<',txt)

Thank you in advance for your assistance.

Try `:\s+([-\s\w]+)<`, see https://regex101.com/r/l6Fw8S/1 – Wiktor Stribiżew Jan 07 '22 at 23:26 — Wiktor Stribiżew, Jan 07 '22 at 23:26
