Python - Flask: render_template() not found
Question: I'm new in flask. I have this code: Will you give me an advice what I'm doing
wrong? Thanks

    
    
    from flask import Flask
    from flask import request
    from flask import render_template
    
    app = Flask(__name__)
    
    @app.route('/')
    def my_form():
        return render_template('my-form.html')
    
    @app.route('/', methods=['POST'])
    def my_form_post():
    
        text = request.form['text']
        processed_text = text.upper()
        return processed_text
    app.debug = True
    print("asdsa")
    if __name__ == '__main__':
        app.run()
    

I have put file my-form.html into this folder: C:\Python33\Lib\site-
packages\flask\testsuite\templates

But when I refresh the 127.0.0.1:5000 I get
jinja2.exceptions.TemplateNotFound:

Answer: You put your template in the wrong place. From the Flask docs:

> Flask will look for templates in the templates folder. So if your
> application is a module, this folder is next to that module, if it’s a
> package it’s actually inside your package:

See the docs for more information:
<http://flask.pocoo.org/docs/quickstart/#rendering-templates>
