*For Python 2.7.*
|
|
|
|
One of the reasons everybody loves Python is the interactive shell. It
|
|
basically allows you to execute Python commands in real time and
|
|
immediately get results back. Flask itself does not come with an
|
|
interactive shell, because it does not require any specific setup upfront,
|
|
just import your application and start playing around. ::
|
|
|
|
$ pip install bpython
|
|
|
|
And we can now install Python 2.7: ::
|
|
|
|
$
|
|
|
|
|
|
The **--framework** option tells Python

-------------------------------

|
Say you have a utility function that returns the URL the user should be
|
|
redirected to. Imagine it would always redirect to the URL's ``next``
|
|
parameter or the HTTP referrer or the index page::
|
|
|
|
$ curl -O http://python-distribute.org/distribute_setup.py
|
|
$ python distribute_setup.py
|
|
|
|
As you can see, it accesses the request object. If you try to run this
|
|
from a plain Python shell, this is the exception you will see: ::
|
|
|
|
$ easy_install pip
|
|
|
|
Hopefully you'll never have to use **easy_install** again.

|
By just creating a request context, you still don't have run the code that
|
|
is normally run before a request. This probably results in your database
|
|
being unavailable, the current user not being stored on the
|
|
:data:`~flask.g` object etc.
