I am trying / wanting to write a Python script (2.7) that goes to a form on a website (with the name "form1") and fills in the first input-field in said form with the word hello, the second input-field with the word Ronald, and the third field with [email protected]

Aside from Mechanize and Selenium David has mentioned, it can also be achieved with Requestsand BeautifulSoup.
除了大卫提到的机械化和硒之外，它还可以通过Requests和来实现BeautifulSoup。
To be more clear, use Requeststo send request to and retrieve responses from server, and use BeautifulSoupto parse the response html to know what parameters to send to the server.
为了更清楚，用于Requests向服务器发送请求和从服务器检索响应，并用于BeautifulSoup解析响应html以知道要发送给服务器的参数。
Here is an example script I wrote that uses both Requestsand BeautifulSoupto submit username and password to login to wikipedia:
这是我编写的示例脚本，它同时使用Requests和BeautifulSoup提交用户名和密码以登录维基百科：
import requests
from bs4 import BeautifulSoup as bs
def get_login_token(raw_resp):
soup = bs(raw_resp.text, 'lxml')
token = [n['value'] for n in soup.find_all('input')
if n['name'] == 'wpLoginToken']
return token[0]
payload = {
'wpName': 'my_username',
'wpPassword': 'my_password',
'wpLoginAttempt': 'Log in',
#'wpLoginToken': '',
}
with requests.session() as s:
resp = s.get('http://en.wikipedia.org/w/index.php?title=Special:UserLogin')
payload['wpLoginToken'] = get_login_token(resp)
response_post = s.post('http://en.wikipedia.org/w/index.php?title=Special:UserLogin&action=submitlogin&type=login',
data=payload)
response = s.get('http://en.wikipedia.org/wiki/Special:Watchlist')

For your specific case, here is the working code:
对于您的具体情况，这是工作代码：
import requests
from bs4 import BeautifulSoup as bs
def get_session_id(raw_resp):
soup = bs(raw_resp.text, 'lxml')
token = soup.find_all('input', {'name':'survey_session_id'})[0]['value']
return token
payload = {
'f213054909': 'o213118718', # 21st checkbox
'f213054910': 'Ronald', # first input-field
'f213054911': '[email protected]',
}
url = r'https://app.e2ma.net/app2/survey/39047/213008231/f2e46b57c8/?v=a'
with requests.session() as s:
resp = s.get(url)
payload['survey_session_id'] = get_session_id(resp)
response_post = s.post(url, data=payload)
print response_post.text
