It's simple. If you want to retrieve a specific object simply add the name of the variable within session, e.g. session['nickname'].

You can set the variable the same way, by doing session['nickname'] = nickname.

In your case you would change it to the following

if 'user' in session:
    user = session['user']
    print user

if 'nickname' in session:
    nickname = session['nickname']
    print nickname

This is an simplified version of the function I use for login.

@app.route('/login', methods=['POST'])
def login():
    """Authenticate User"""
    username = request.form['username'].strip()
    nickname = request.form['nickname'].strip()
    password = request.form['password']
    try:
        if Auth().VerifyLogin(username, password):
            session['username'] = username
            session['nickname'] = nickname
        else:
            # failed to login, do something.
    except Exception as why:
        app.logger.critical('.....')
