How to set a generated key in mongodb using python?

Question

I am using mongodb in python. The problem I'm facing is during the generation of a key. The code through which I'm generating a key is:

post_id = posts.insert_one({msg["To"]:a}

Now here, the "To" consist of an email address (which consists of a symbol dot(.)). I researched few documents online and I got to knew that “To” of a mail cannot be used as a key, because in mongodb they use “.(dot)” and “$” as a nested document.

So now how can I proceed?

You could replace dot with some other symbol before inserting — kvorobiev

E-mail address is just a string. You can come up with numerous conversions into better keys. For example, you could convert it to an md5 hash of the e-mail address. — msvalkon
