Python eval() - Evaluate Expressions Dynamically

Показать описание
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.

thanks so much i had a problem in a code
that had to do something like this
create a variable (var_1) that would be 1 of a list of complex variables ) or could be 1 class from a list of dataclasses
i needed to load data in to a variable
but the variable is defined only in execution
and this works
code = "variable_1 = " + + "()"
exec(code)
thanks <3<3
