You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...
In this step-by-step tutorial, you'll learn the basics of how to use Python. With this knowledge, you'll be able to start coding your Python applications.
