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.
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 learn:
- How Python’s
- How to use
eval()to dynamically evaluate arbitrary string-based or compiled-code-based input
eval()can make your code insecure and how to minimize the associated security risks
The code in this course was tested with Python 3.9.0,
eval() has not changed much and older versions should be compatible.
