upload file to google storage using Python Google App engine API

I am following Massimiliano Pippi's Python for Google App engine. In chapter 3, we are trying to upload a file that the user of my app select thanks to this html code:

<div class="form-group">
            <label for="uploaded_file">Attached file:</label>
            <input type="file" id="uploaded_file" name="uploaded_file">
</div>

And from the python part, in my MainHandler on webapp2, I get the request content using:

def post(self):
    uploaded_file = self.request.POST.get("uploaded_file", None)
    file_name = getattr(uploaded_file, 'filename')
    file_content = getattr(uploaded_file, 'file', None)
    content_t = mimetypes.guess_type(file_name)[0]

    bucket_name = app_identity.get_default_gcs_bucket_name()
    path = os.path.join('/', bucket_name, file_name)
    with cloudstorage.open(path, 'w', content_type=content_t) as f:
        f.write(file_content.read())

The problem is that the variable uploaded_file is handled as if it was a file by Massimiliano Pippi, but my Python tells me that this variable is a unicode containing the name of the file. Therefore, when I try file_name = getattr(uploaded_file, 'filename'), I get an error.

Obviously, the code in the book is false, how can I fix it?

Ok so after Tim's advice, I chcked the doc of WebOb and notice that in the html file, I should have put enctype="multipart/form-data" as follows:

<form action="" method="post" enctype="multipart/form-data">
    <div class="form-group">
        <label for="uploaded_file">Attached file:</label>
        <input type="file" id="uploaded_file" name="uploaded_file">
    </div>
</form>

Instead of:

<form action="" method="post">
    <div class="form-group">
        <label for="uploaded_file">Attached file:</label>
        <input type="file" id="uploaded_file" name="uploaded_file">
    </div>
</form>
