pytest

that doesn't make much sense and there are necessary uses for eval() /exec(), mostly for dynamic creation of code: For example here's Python dataclasses in the standard library using exec() to create the `__init__` and other methods that go on your dataclass: https://github.com/python/cpython/blob/main/Lib/dataclasses.... Here's Pydantic using it for a jupyter notebook check: https://github.com/pydantic/pydantic/blob/594effa279668bd955... here's Pytest using it to rewrite modules so that functions like assert etc. are instrumented by pytest: https://github.com/pytest-dev/pytest/blob/eca93db05b6c5ec101...

All of these libraries are
