Python字典按字符拆分字符串键

时间：2019-05-13 13:42:41

标签： python

我是Python的新手，我在字典方面遇到了一些问题。

我的目标是获得如下字典：

done_dict = {orthogroup1：1，orthogroup2：1，orthogroup3：1}

到目前为止，我有以下内容：

for orthogroup_name in done_match:
    split_name =  orthogroup_name.split('.')
    split_name = split_name[0]
    done_dict = dict.fromkeys(split_name)
    done_dict = dict.fromkeys
    print(done_dict)

有了这个，我得到这样的东西：

{'g': None, 'h': None, 'o': None, '1': None, 'p': None, 'r': None, 'u': None, 't': None, '6': None, '8': None}

有人可以帮忙解释一下如何将None变成1，以及如何让python不要将每个字符都分割成一个新键吗？

非常感谢您！
