如何将数字对 (str) 转换为数字对 (int)

例如我有：

lst = ['1,2' , '3,4' , '6,5']

我怎样才能做到：

  1. Best Answer
    lst = ['1,2' , '3,4' , '6,5']
newLst = [[int(j) for j in i.split(',')] for i in lst]
print(newLst)  # [[1, 2], [3, 4], [6, 5]]

  2. 例如像这样：

    lst = ['1,2' , '3,4' , '6,5']
new_list = []
for element in lst:
    data = element.split(',')
    print(data)
    nlst = []
    nlst.append(int(data[0]))
    nlst.append(int(data[1]))
    new_list.append(nlst)

print(new_list)

  3. lst = ['1,2', '3,4', '6,5']
newLst = [list(map(int, x.split(','))) for x in lst]
print(newLst)
