遍历嵌套列表到 append 仅整数
[英]Iterating through a nested list to append only integers
问题描述
How can I iterate through this list to then store only the first numbers in each element of the list?
我怎样才能遍历这个列表，然后只存储列表的每个元素中的第一个数字？ So for the first element in the list I would want to basically have maybe a list which would be lst = [199] and then for the second element it would be lst = [199, 196] and then for the third, lst = [199, 196, 203].因此，对于列表中的第一个元素，我基本上希望有一个列表，它可能是 lst = [199]，然后对于第二个元素，它将是 lst = [199, 196]，然后对于第三个元素， lst = [ 199、196、203]。
['Ball Apple 199 4', 'Banana Car 196 7 ', 'Cherry Grape 203 8']
