python - 从列表中的字符串创建字典？

Question

我有一个列表 ['111,"A","yes"','112,"B","no"','113,C,"maybe"'] 我希望输出为 {111:('A',"yes"),112:('B',"no"),113:('C',"maybe")]}

我尝试遍历列表，然后遍历字符串，但最终遍历了 1,1,1 而不是 111 作为一个完整数字。

Answer 1

使用str.split() :

In [1]: lst = ['111,"A","yes"','112,"B","no"','113,C,"maybe"']

In [2]: dict((int(s[0]), s[1].split(',')) for s in (grp.split(',', 1)
                                          for grp in lst))
Out[2]: {111: ['"A"', '"yes"'],
         112: ['"B"', '"no"'],
         113: ['C', '"maybe"']}
