python: convert “5,4,2,4,1,0” into [[5, 4], [2, 4], [1, 0]]

Question

Is there a \"straightforward\" way to convert a str containing numbers into a list of [x,y] ints?

# from: \'5,4,2,4,1,0,3,0,5,1,3,3,14,32,3,5\'
# to: [[5, 4         


        

Answer 1

It may be interesting to have a generator. Here's a generator expression:

import re
ch = '5,4,2,4,1,0,3,0,5,1,3,3,14,32,3,5'
genexp = ( map(int,ma.groups()) for ma in re.finditer('(\d+)\s*,\s*(\d+)',ch) )
