Python - Flask：找不到 render_template() [重复]

我是烧瓶新手。我有这个代码： 你能给我一个建议吗？我做错了什么？谢谢

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()

我已将文件 my-form.html 放入此文件夹中： C:\Python33\Lib\site-packages\flask\testsuite\templates

但是当我刷新 127.0.0.1:5000 时，我得到 jinja2.exceptions.TemplateNotFound：

您将模板放在错误的位置。来自烧瓶文档：

Flask 将在 templates 文件夹中查找模板。因此，如果您的应用程序是一个模块，则此文件夹位于该模块旁边，如果它是一个包，则它实际上位于您的包内：
