309 This blog post by Jean-Paul Calderone is commonly given as an answer in #python on Freenode. Filesystem structure of a Python project Do: name the directory something related to your project. For example, if your project is named "Twisted", name the top-level directory for its source files Twisted.
That is its primary purpose. Without the else-clause, the only option to run additional code before finalization would be the clumsy practice of adding the code to the try-clause. That is clumsy because it risks raising exceptions in code that wasn't intended to be protected by the try-block.
The current code generator emits no code for an assert statement when optimization is requested at compile time. - Python 2 Docs Python 3 Docs If you use assert to implement application functionality, then optimize the deployment to production, you will be plagued by "but-it-works-in-dev" defects. See PYTHONOPTIMIZE and -O -OO
In Java the code is structured in packages with you each class in a separate file. Is there any similar practice in python? Is it better to have each class in a different python file and have them ...
The usage is clearly not bad practice here; you define the input and merely observe behavior. eval is handy for testing. Take a look at this search for eval, performed on the CPython git repository; testing with eval is heavily used.
The goal is to simplify using many arguments in a Python program by writing a config (settings) file that dynamically can add an item. What is the best practice for using a settings (config) file or importing a library in Python? use case: Rather than using pickle I would like it to be a straightforward text file that can easily be read and edited.
I am new to Python as I want to expand skills that I learned using R. In R I tend to load a bunch of libraries, sometimes resulting in function name conflicts. What is best practice in Python. I h...
It is not bad practice to have scopped imports. So that the import applies only to the function you used it in. I think the code would be more readable though if the imports where grouped together at the top of the block or if you want it globally at the top of the file.
2 If try-except-finally is nested inside a finally block, the result from "child" finally is preserved. I have not found an official explanation yet, but the following code snippet shows this behavior in Python 3.6.
