Browser() in Python shows errors in IDLE

I have some code here which is basically a bot that spams a specific google form:

while True:
    browser = Browser()
    print("Form Filling Begun")
    browser.visit('https://docs.google.com/forms/d/1Lyoox1FIpOP5nceVHqmdA3Exqf8PMCxaBgWIYQ67yX8/viewform?c=0&w=1')
    browser.fill('entry.1796849606', 'test')
    browser.fill('entry.1233774681', 'test')
    browser.fill('entry.1687034525', 'test')
    browser.fill('entry.2085519362', 'test')
    browser.fill('entry.2085519362', 'test')
    browser.fill('entry.87435301', 'test')
    browser.find_by_name('entry.434307791', 'test')
    browser.find_by_name('submit').click()
    print("Form Filled")
    browser.quit()
    time.sleep(10)

When I ran it in IDLE, it said there was a problem on line 2. That Browser() wasn't defined. Now, I know that my friend was able to accomplish this with this code, so I'm not sure what's wrong. I'm sure it's a really basic problem, but I'm a complete n00b at Python, so I don't really know what to do.

Thanks,

Sam.

EDIT: So I went on the Splinter website and put its own sample code in IDLE, to see what happens and this is what the console was showing

I'm out of my depth here. When it opened a browser window, the URL was about:blank&utm_content=firstrun. What does that mean??

Do you import browser? Try:
