How to call a javascript function using python script?

Question

I am doing a web scraping project in which i stumbled upon a web page that has captcha. Now the thing is that the link that captcha is only shown when i hit refresh captcha button, which is in fact a java-script function called refresh capthca. Here is the code of button :

     <a title="Request a new validation code." href="javascript: refreshCaptcha();"      onclick="#">
     <img src="index.jpg" border="0" style="vertical-align:bottom;" width="23" height="22"></a>

How to call that function or click on that refresh captcha button using python script?

where is the code of button ?

If you have node installed you can use the subprocess module

from subprocess import call
call(['node', '-e', 'JavaScript', 'code', 'here'])
