So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话,这样我们就有氢与碳之间的单键和碳与氮之间三键,然后还有一对孤对电子在氮这里。
Because Python doesn't fully support lexical variables, you have to create a data structure to hold the value of n.
因为Python并不完全支持局部变量,你不得不创造一种数据结构,来接受n的值。
If you work with a context-free grammar, the structure of n-gram (see Resources) might be what you require.
如果您使用一种上下文无关的文法,那么n元语法的结构(参见参考资料)可能是您所需要的。

So, in terms of finishing our Lewis structure, we're actually not done yet here, even though we have full octets, and we've used up all of our valence electrons, and the reason is because it's c n minus, so we need to make sure that that's reflected in our Lewis structure, so let's put it in brackets here, and put a minus 1.
那么,根据我们的路易斯结构的完成情况,我们实际上还没有全部完成,尽管我们有了填满的“八隅体“,而且用完了所有的价电子,原因就是因为这是一个负离子,我们需要确保我们的路易斯结构能反映出这一点,所以让我们给它加个括号,再加个负一。
