AttributeError: 'SwitchTo' object has no attribute 'new_window' Selenium

Question

I am using selenium in a personal project, and i want to create a new tap. i read the selenium documentation about it and found this method:

# Opens a new tab and switches to new tab
driver.switch_to.new_window('tab')

But when i run this code, it throws:

AttributeError: 'SwitchTo' object has no attribute 'new_window'

So i find this question about creating new tabs and find this. It works for me, but my question is if for you that method works. i also saw the selenium api and i could not find that method in the WebDriver module.

i am using:

• firefox 96.0
• geckodriver v0.30.0
• python 3.9.7
• selenium 4.1.0
• jupyter notebook 6.4.5

Here is the part of the code:

for grade in grades:
            grade.click()
            div_classes= WebDriverWait(grade, 5).until(EC.element_to_be_clickable((By.CSS_SELECTOR, '.in')))
            div_rows= div_classes.find_element(By.CSS_SELECTOR, '.row')
            if len(div_rows.find_elements(By.TAG_NAME, 'div')) > 0:
                a= div_rows.find_element(By.TAG_NAME, 'a')
                original_window = driver.current_window_handle
                driver.switch_to.new_window('tab')
                driver.get(a.get_dom_attribute('href'))

Here is the html part of the page (to get the grades there is some js that it is executed):
