Where does username come from (if username)?

I do not really understand where does username come from? We say if username =! ... but which username we are referring to?

@app.route('/stream')
@app.route('/stream/<username>')
def stream(username=None):
    template = 'stream.html'
    if username and username != current_user.username:
        user = models.User.select().where(models.User.username**username).get() # ** compare if match
        stream = user.posts.limit(100)
    else: # our username
        stream = current_user.get_stream().limit(100)
        user = current_user
    if username:
        template = 'user_stream.html'
    return render_template(template, stream=stream, user=user)

Username is coming from the query string in the url "/stream/username"

So the idea being when you navigate to "/stream/username" you want to do a check to see if the request is for a anonymous user or the logged in user. 

@app.route('/stream')
@app.route('/stream/<username>')
def stream(username=None):
    template = 'stream.html'
    # anonymous user
    if username and username != current_user.username:
        user = models.User.select().where(models.User.username**username).get() # ** compare if match
        stream = user.posts.limit(100)
    else: # our username
        stream = current_user.get_stream().limit(100)
        user = current_user
    if username:
        template = 'user_stream.html'
    return render_template(template, stream=stream, user=user)
