是INFO我正在使用list进行排序，并希望输出采用字典的形式。但是，我得到了不必要的字符：
Counter不必要的字符是：
wanted_dict = collections.Counter(INFO)
>>> Counter({'BLA': 102, 'BLABLA': 96, 'BLABLABLA': 96...})
有没有办法输出以下内容？
Counter
(

答案 0 :(得分：2)
将其包裹在dict电话中。
>>> dict(Counter({'BLA': 102, 'BLABLA': 96, 'BLABLABLA': 96}))
{'BLABLABLA': 96, 'BLABLA': 96, 'BLA': 102}
您可以使用此方法将大多数特殊collections字典对象转换为普通字典。
