I think they are worth for more complex apps (I actually have a draft blog post with some experiments I did using PEX + gunicorn), but for my use case, it's not worth the effort when I only need the standard library.
For example,
#! /usr/bin/env -S pip-run Jinja2==3.*
from jinja2 import Environment
env = Environment(autoescape=True)
template = env.from_string("Hello, {{ name }}!")
print(template.render(name="world"))
Edit: fades caches virtualenvs.
#! /usr/bin/env fades
from jinja2 import Environment # fades Jinja2==3.*
env = Environment(autoescape=True)
template = env.from_string("Hello, {{ name }}!")
print(template.render(name="world"))I like to set up at least some tests on my scripts so that I can reduce the number of times I push something out that is obviously broken. pre-commit can also help with preventing shipping things with syntax errors if you enable the "ast" check, which does a simple syntax check on the code.
