How to Scroll down a Dialog box with Selenium + Python

Question

I have a dialog box from a medical web app which shows only 30 patients in the first screen, to view more pacients i have scroll down the dialog box and when i close to the thirtieth pacient it shows 30 more.

I'm trying to show more than 2000 paciente on that dialog box while I'm opening in a new window their link profile and collecting info and saving in a xmls file.

How can I scroll down using Python + Selenium?

This is the dialog box screen:

This html is the dialog box with the 6 first firsts patients and thirtieth, I couldn't post all the 30 (character limit):

This is my code where i'm tryong to scroll down:

element = driver.find_element(By.XPATH("//div[@class='md-dialog-container']//md-list-item[30]"))#Select last child of content div driver.execute_script("arguments[0].scrollIntoView(true);", element) #Scroll to last child node

But I'm receving the message error:

element = driver.find_element(By.XPATH("//div[@class='md-dialog-container']//md-list-item[30]")) #Select last child of content div TypeError: 'str' object is not callable

This error message...

TypeError: 'str' object is not callable

...implies that your program have invoked a function() which is actually a property.

As per Selenium doc this is the right method signature:

find_element(by='id', value=None)

Find an element given a By strategy and locator. Prefer the find_element_by_* methods when possible.
Usage :   element = element.find_element(By.ID, ‘foo’)
Return type:  WebElement

And this is mentioned in doc

def find_element(self, by=By.ID, value=None):
    """
    Find an element given a By strategy and locator. Prefer the find_element_by_* methods when
    possible.

    :Usage:
        element = element.find_element(By.ID, 'foo')

    :rtype: WebElement
    """
    if self._w3c:
        if by == By.ID:
            by = By.CSS_SELECTOR
            value = '[id="%s"]' % value
        elif by == By.TAG_NAME:
            by = By.CSS_SELECTOR
        elif by == By.CLASS_NAME:
            by = By.CSS_SELECTOR
            value = ".%s" % value
        elif by == By.NAME:
            by = By.CSS_SELECTOR
            value = '[name="%s"]' % value

    return self._execute(Command.FIND_CHILD_ELEMENT,
                         {"using": by, "value": value})['value']

So as per method signature you should use either

last_element = driver.find_element(By.XPATH,"//div[@class='md-dialog-container']//md-list-item[30]")
driver.execute_script("arguments[0].scrollIntoView(true);", last_element)

OR

last_element = driver.find_element_by_xpath("//div[@class='md-dialog-container']//md-list-item[30]")
driver.execute_script("arguments[0].scrollIntoView(true);", last_element)
