PDB does not have Request as an available option

I've been doing pretty well following the tasks so far, but I'm having an issue here, and it appears to be with PDB. Here's my app.py:

from flask import Flask, render_template, redirect, url_for
app = Flask(__name__)


@app.route('/')
def index():
    return render_template('index.html')

@app.route('/save', methods=['POST'])
def save():
    import pdb; pdb.set_trace()
    return redirect(url_for('index'))

app.run(debug=True, host='0.0.0.0', port=7999)

when I run the page and try to do request.form, I get:

*** NameError: name 'request' is not defined

Weird, huh?

When I run dir(pdb), I get:

['Pdb', 'Restart', 'TESTCMD', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '_rstr', '_usage', 'bdb', 'cmd', 'code', 'dis', 'find_function', 'getsourcelines', 'glob', 'help', 'inspect', 'lasti2lineno', 'line_prefix', 'linecache', 'main', 'os', 'pm', 'post_mortem', 'pprint', 're', 'run', 'runcall', 'runctx', 'runeval', 'set_trace', 'signal', 'sys', 'test', 'traceback']

...which is not at all the number of options Kenneth has in Workspaces. I'm running Python 3, and as far as I know everything should be up to date, but I can't see request as a part of PDB. What am I missing?
