Python: List of lists of integers to absolute value to single number <p>If i had a list of list of integers say:</p> <blockquote> <p>[['12' '-4' '66' '0'], ['23' '4' '-5' '0'], ['23' '77' '89' '-1' '0']]</p> </blockquote> <p>I wanted to convert the numbers to their absolute values and then to a single number, so the output would be:</p> <blockquote> <p>1246602345023778910</p> </blockquote>
