Casting from list of lists of strings to list of lists of ints in python

Question

I\'m reading some numbers from a data source that represent xy coordinates that I\'ll be using for a TSP-esque problem. I\'m new to python, so I\'m trying to make the most

Answer 1

x = [['565.0', '575.0'], ['1215.0', '245.0'], ['1740.0', '245.0']]
x = [[int(float(j)) for j in i] for i in x]
