预先声明的字典大小限制？
我有一本大字典，我经常在代码中引用，因此我将其在顶部初始化：
import ...
myDictionary = {'a':'avalue','b':'bvalue',...}
code ...
但是当我尝试获取值时，找不到某些键。由于大小限制，Python 似乎正在砍掉我的字典。我尝试搜索谷歌，但找不到任何关于此的信息。
我最终将键：值映射转储到一个单独的文件中，并编写了一个函数，通过读取该文件来构建字典。
很高兴知道为什么会发生这种情况......甚至更好地找到一种更干净的方式来保留我的字典。
编辑：字典有超过 1,700 个键
I have a big dictionary i constantly reference in my code so i have it initialized at the top:
import ...
myDictionary = {'a':'avalue','b':'bvalue',...}
code ...
But when i try to get values, some of the keys are not found. It appears as though Python is chopping my dictionary due to a size limit. I tried searching google but couldn't find anything on this.
I ended up dumping the key:value mappings into a separate file and wrote a function that would build the dictionary by reading in the file.
It would be nice to know why this is happening... even better to find a cleaner way to still have my dictionary.
EDIT: Dictionary has over 1,700 keys

您可能想要查找的一件事是字典中的键不重复。例如，在下面的代码中：
因为我使用了键
'1'两次，所以只出现了最后一个，因此我留下了一个大小为 2 而不是 3 的字典。One thing you might want to look for is that the keys in your dictionary are not duplicates. For example, in the following code:
because I used the key
'1'twice, only the last one appeared and thus I was left with a dictionary of size 2 rather than 3.Python 没有字典大小限制。我的字典有超过 100 万个键。您可以发布更多代码吗？
Python does not have a dictionary size limit. I've had dictionaries with well over 1 million keys. Could you post more of the code?
