I believe they should result in (almost) the same entry into the database. In #1, you are technically inserting the function datetime.now. However, ultimately, the value inserted will be str(datetime.now), which turns out to be the string representation of datetime.now(). So, the only difference is that in the second case, the value of datetime.now() is determined before the .insert() method is called, and in the first case, the value is determined within the call to .insert() (the difference in time would probably only be microseconds). Note, you should use #2, as the fact that #1 works is due to an implementation detail (i.e., the fact that str() is applied to the value provided) -- you should not rely on that behavior, as it could change in the future, which would break your code.
