Selenium/python click to open multiple rows
I am trying to scrape the data in a bunch of rows. I am able to expand an individual row using the following:
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, '//*[@id="7858101"]'))).click()
The problem is each row has a different id. They have common class name so I have also tried:
WebDriverWait(driver, 60).until(EC.presence_of_elements_located((By.CLASS_NAME, 'course-row normal faculty-BU active'))).click()
I have attached a few rows below Any suggestions on how I can fix this

Solution
Are almost there...
You can retrieve a list of all the relevant web elements with the use of driver.find_elements method and then to iterate over each element in the list clicking on it.
Since course-row normal faculty-BU active is actually several class names, not a single class name, you should use XPath or CSS Selector there.
Also it's recommended to use visibility_of_element_located expected condition here, not presence_of_elements_located since the former condition is fulfilled even when the web element is not finally rendered on the page while visibility_of_element_located expected condition waits for more mature state of the web element
WebDriverWait(driver, 60).until(EC.visibility_of_element_located((By.XPATH, '//tr[@class = "course-row normal faculty-BU active"]')))
time.sleep(0.4) #short delay added to make ALL the elements loaded
elements = driver.find_element(By.XPATH, '//tr[@class = "course-row normal faculty-BU active"]')
for element in elements:
element.click()
#scrape the data you need here etc
