Hermes Bot b6ca6c99f4 fix: move ssl import out of TYPE_CHECKING to fix NameError in CertParamType
The ssl module was only imported under TYPE_CHECKING but was referenced
in the runtime class signature of CertParamType (click.ParamType[..., ssl.SSLContext]).
With --future annotations, this should work, but click.ParamType is not subscriptable
and the type argument triggers eager evaluation.

Fix: import ssl unconditionally and remove the subscript from ParamType
since it is not a generic type.

Tests: 491 passed

Flask

Flask is a lightweight WSGI web application framework. It is designed to make getting started quick and easy, with the ability to scale up to complex applications. It began as a simple wrapper around Werkzeug and Jinja, and has become one of the most popular Python web application frameworks.

Flask offers suggestions, but doesn't enforce any dependencies or project layout. It is up to the developer to choose the tools and libraries they want to use. There are many extensions provided by the community that make adding new functionality easy.

A Simple Example

# save this as app.py
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello, World!"
$ flask run
