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

#declare the string of numbers
str_nums = '5,4,2,4,1,0,3,0,5,1,3,3,14,32,3,5'

#zip two lists: the even elements with the odd elements, casting the strings to integers
zip([int(str_nums.split(',')[i]) for i in range(0,len(str_nums.split(',')),2)],[int(str_nums.split(',')[i]) for i in range(1,len(str_nums.split(',')),2)])

Of course you would want to clean this up with some intermediate variables, but one liners like this is why I love Python :)
