I made an opposite journey. While working in C and Java I commented heavily, but in Python I prefer to just leave a comment here and there if I'm not sure the reason for the code and its intent are clear - but at the same time a comment is also a powerful signal for me to rethink that piece of code and make it more obvious. I find both of your examples readable to about the same level; MySQL one because the naming is helpful (`number_of_bytes_read_from_buffer`) and SQLite one because of the comments - I would be lost without them. For example, why is a function that does "Release the STATIC_MASTER mutex" called "leaveMutex"? On the other hand, SQLite comments explain much more about how the code is used, what assumptions are made, so this is really a bonus.
