In this talk, we will discuss the low level foundations of what a raw pointer is--a variable that stores an address. We will then see some examples of raw pointers for creating data structures, passing pointer is a variable that stores the memory address of a specific object type ○ (Let’s look at an example) 13What is a Pointer?

columns. For the twitter clone, there are just three models: User: Represents a user account and stores the username and password, an email address for generating avatars using gravatar, and a datetime that contains two foreign-keys to the User model and stores which users follow one another. Message: Analagous to a tweet. The Message model stores the text content of the tweet, when it was created, MySQL database my_db. More examples in the db_url documentation. Multi-threaded applications peewee stores the connection state in a thread local, so each thread gets its own separate connection. If you prefer
