Python gets part of the data from the text?

Question

I want to remove the key:value before the first decimal in each line, and remove the key and colon of the first key-value pair. The processing result is for example the first line. Should be
8 Timbuktu 0.022202129797066508 0.024390243902439025

Answer 1

a=First row of data
b=a.split(' ')
res=b[0]+b[1].split(':')[1]+b[3]+b[4]
Like it and accept it

Answer 2

line.replace(/(?<=^\d )\d+:([^ ]+) [^ ]+/, '');

Python is not installed. This is how it is represented by js (js does not support reverse order)
