from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0

# Create a new instance of the Firefox driver
driver = webdriver.Firefox()

# go to the baidu home page
driver.get("http://www.baidu.com")

# the page is ajaxy so the title is originally this:
print driver.title

# find the element that's name attribute is q (the baidu search box)
inputElement = driver.find_element_by_name("wd")

# type in the search
inputElement.send_keys("cheese!")

# submit the form (although baidu automatically searches now without submitting)
inputElement.submit()

try:
    # we have to wait for the page to refresh, the last thing that seems to be updated is the title
    WebDriverWait(driver, 10).until(EC.title_contains("cheese!"))

    # You should see "cheese! - baidu Search"
    print driver.title

finally:
        driver.quit()

运行如下：
百度一下，你就知道
cheese!_百度搜索
