字典更新序列元素错误 [英] dictionary update sequence element error
问题描述
我有好几个字典文件,我想用这段代码打开每个文件并把它加到一个集合中,以便以后比较和匹配.基本上我有所有可能字符的所有排列的不同列表,我需要知道排列是否在字典中.但是,当我尝试使用所有字典行进行设置时,出现此错误:
choices = ['s','m','o','k','e','j','a','c','k']def解析(选择):我的集合 = {}对于选择项:文件名 = self.location + "/dicts/%s.txt" % (item)mySet.update(open(filename).read().splitlines())返回我的集合
我收到此错误
错误:字典更新序列元素#0 的长度为4;2 是必需的
另外,我想问一下,是否有可能在不到 1 分钟的时间内运行的两组数据(9 个字符排列和 9 个字典文件列表)之间的比较方法.
我知道已经有关于这个错误的问题,但坦率地说,我是一个初学者,我不明白这些问题与我的代码有什么关系,或者如何修复它.
如果你写:
mySet = {}
mySet
是不是set
,而是字典(是的,这很令人困惑).例如:
为了构造一个空集,你应该使用:
mySet = set()
set
确实有一个函数 update
,它将所有添加到集合中的可迭代元素作为输入.另一方面,字典需要可迭代的元组(或字典等)
I have several dictionary files, I want this code to open each file and add it to a set, for later comparison and matching. Basically I have a different list of all permutations of all possible characters and I need to know if permutation is in dictionary. But when I try to make a set with all dictionary lines I get this error:
choices = ['s','m','o','k','e','j','a','c','k']
def parsed(choices):
mySet = {}
for item in choices:
filename = self.location + "/dicts/%s.txt" % (item)
mySet.update(open(filename).read().splitlines())
return mySet
I get this error
error: dictionary update sequence element #0 has length 4; 2 is required
Furthermore, I'd like to ask if there's a possible comparison method between two sets of data (9 character permutations, and 9 dictionary files list) that runs in less than 1 minute.
I understand that there are already questions regarding this error, but frankly I'm a beginner and I don't understand how those relate to my code, or how to fix it.
If you write:
mySet = {}
mySet
is not a set
, but a dictionary (yeah that is confusing). For instance:
>>> type({})
<class 'dict'>
In order to construct an empty set, you should use:
mySet = set()
A set
indeed has a function update
that takes as input an iterable of elements that are all added to the set. A dictionary on the other hand requires an iterable of tuples (or a dictionary, etc.)
