Package the script for distribution.

Sometimes when the network is slow, or the server takes too long to reply, the following line gives an error:

    el = driver.find_element_by_id('Dt1')

Because, the page is reloaded before this happens, and apparently the script keeps running without waiting for the page to reload. A simple fix - add wait() every time elem.send_keys(Keys.RETURN) is executed (in the latestSem function), and modify the getGPA function to this:

def getGPA(rno, sem_id_value):
    elem = driver.find_element_by_name("TextBox1")
    elem.send_keys(Keys.CONTROL, 'a')
    elem.send_keys("\b")
    elem.send_keys(rno)
    elem.send_keys(Keys.RETURN)
    wait()
    el = driver.find_element_by_id('Dt1')
    for option in el.find_elements_by_tag_name('option'):
        if option.get_attribute('value') == sem_id_value:
            option.click()
    wait()
    name = driver.find_element_by_id('LblName').text
    gpa = driver.find_element_by_id('LblGPA').text
    print(str(rno) + "\t" + name + "\t" + gpa)  # Note the brackets - the only line that makes the original script incompatible with py3 is this one.

Here, wait() can be defined to be time.sleep(1). Of course, 1 second might not be enough, so the user will probably still need to modify the script (but only the wait() function).

Alternative is to somehow wait for the page to reload. I don't know how to do that in selenium. Haven't used it before. But this simple hack sufficed for me.
