Print a text of textbox in HTML with Flask after pressing a button

This is my first exercise in Flask and I would like to understand what I am doing wrong here.

I want to insert a text in a textbox and then visualize it in HTML I have already looked many answers on StackOverflow, including this: Set a python variable in flask with a button and javascript

This is my python code:

from flask import Flask, render_template, request

app = Flask(__name__)

@app.route("/")
def my_form():
    return render_template('test.html')

@app.route("/", methods=['GET','POST'])
def func_test():
    if request.method == 'POST':
        text = request.form['Value1']
        return render_template('test.html', value1=text)

if __name__ == "__main__":
    app.run(port=5000, debug=True)

and this is my HTML:

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form methods="POST">
<p>Login </p><br>
    <p>Value1 <input type = "text" name = "Value1" /></p>
    <p><input type = "submit" value = "submit" name = "submit" /></p>

</form>
input is {{value1}}
</body>
</html>

What I would like is that after the text is written in the textbox and the button is pressed, the text is printed after input is

Thanks

Solution

well, you can wrap your txt result in an if block that only shows when there is value

   {% if value %}
   input is {{value1}}
   {% else %}
    input is: 
    {% endif %}

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form method="POST">
<p>Login </p><br>
    <p>Value1 <input type = "text" name = "Value1" /></p>
    <p><input type = "submit" value = "submit" name = "submit" /></p>

</form>
input is {{value1}}
</body>
</html>
