As a developer, you may sometimes need to send complex object hierarchies over a network or save the internal state of your objects to a disk or database for later use. To accomplish this, you can use a process called serialization, which is fully supported by the standard library thanks to the Python pickle module. In this course, you’ll learn: What it means to serialize and deserialize an object Which modules you can use to serialize objects in Python Which […]

The Django framework comes with a powerful administrative tool called admin. You can use it out of the box to quickly add, delete, or edit any database model from a web interface.

The built-in Python function eval() is used to evaluate Python expressions. You can pass a string containing Python, or a pre-compiled object into eval() and it will run the code and return the result. Although Python’s eval() is an incredibly useful tool, the function has some important security implications that you should consider before using it. In this course, you’ll learn how eval() works and how to use it safely and effectively in your Python programs. In this tutorial, you’ll […]
