To add a button that autofills a random password on the password field which I created using py-script

I created a form in html which returns to a function in views.py in django framework. I wanted to add a button which autofills the password field with a random password. I used pyscript for creating a random password. But the button seems to be returning to the views.py instead of autofilling.

<body bgcolor="white">
    <py-script>
    import random
    password = ''
    def mypass():
       length = random.randint(8,16)
       list1=[]
       for i in range(0,length):
           list1.append(chr(random.randint(32,126)))
       password = ''.join(list1)
    pyscript.write('python', password)
    </py-script>
    <script>
        function myfun(){
            var a = document.getElementById("password1").value;
            var b = document.getElementById("password2").value;

            if(a!=b){
                document.getElementById("messages").innerHTML="Passwords do not match";
                return false;
            }
        }
    </script>
    <script>
        function myfunction(){
            var password = PyScript.interpreter.globals.get('password');
            document.getElementById("password1").value = password;
       } 
    </script>
    <form onsubmit="return myfun();" action="register" method="post" >
        {% csrf_token %} 
        
        <p>
            <label for="user_name">User Name</label>
            <input type="text" name="user_name" id="user_name" placeholder="Antman56." autocomplete="on" >
        </p>
        <p>
            <label for="f_name">First Name</label>
            <input type="text" name="f_name" id="f_name" placeholder="Dave" autocomplete="on" >
        </p>
        <p>
            <label for="l_name">Last Name</label>
            <input type="text" name="l_name" id="l_name" placeholder="Lee" autocomplete="on" value="keyan" >
        </p>
        <p>
            <label for="email">Email ID</label>
            <input type="email" name="email" id="email" placeholder="[email protected]" autocomplete="on" >
        </p>
        <p>
            <label for="password1">Password</label>
            <input type="password" name="password1" id="password1" placeholder="123$aBc" >
        </p>
        <p>
            <label for="password2">Confirm Password</label>
            <input type="password" name="password2" id="password2" placeholder="123$aBc" ><span id="messages" style="color:red"></span>
        </p>
        <div id="python"></div>
        <button onclick="mypass()">create random password</button>
        <button onclick="myfunction()">fill the random password</button>
        <input type="submit" value="Submit" >
      
    </form>

when I click the ‘create random password’, I expect the mypass function in pyscript to execute and when I click the ‘fill the random password’ button, I want to execute the myfunction function and autofill my password field with the random password previously generated.
