How would I go about converting a list of list of integers to a single string in Python. The numbers in the sublist would be separated by a space and the sublists by a comma.
Like this:
input = [[1,2,3],[4,5,6],[7,8,9]]
output = '1 2 3, 4 5 6, 7 8 9'
you can use the join function in python to achieve the result
print(", ".join([ " ".join([str(a) for a in x]) for x in input]))
PS:
if you want to concatenate the list, there is a chain functionality in itertools that can help you achieve this
from itertools import chain
input = [[1,2,3],[4,5,6],[7,8,9]]
print(list(chain(*input)))
although you should try to do it with simple loops first as well for your practice and building logic
[1, 2, 3, 4, 5, 6, 7, 8, 9] which is different than the OP's desired output of 1 2 3, 4 5 6, 7 8 9
input. Doing that replaces theinputfunction.', '.join(' '.join(str(x) for x in s) for s in xnput)
