多处理没有做多进程

Question

在python中，我创建了4个进程来同时打开多个选项卡但是选项卡按顺序打开但不是小部件。

代码是：

from selenium import webdriver
from multiprocessing import Process
from selenium.webdriver.common.keys import Keys


def func1(driver):
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
    driver.switch_to.window(driver.window_handles[-1])
    driver.get('http://www.rediff.com')
    driver.implicitly_wait(20)
    driver.get('http://yatra.com')
    driver.implicitly_wait(50)
    driver.get('http://makemytrip.com')

def func2(driver):
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
    driver.switch_to.window(driver.window_handles[-1])
    driver.get('http://www.stackoverflow.com')
    driver.implicitly_wait(10)
    driver.get('http://www.facebook.com')
    driver.refresh()


def func3(driver):
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
    driver.switch_to.window(driver.window_handles[-1])
    driver.get('http://www.yahoo.com')
    driver.refresh()




if __name__=='__main__':
     driver = webdriver.Chrome()
     driver.get('https://www.google.com')
     p1 = Process(target = func1(driver))
     p1.start()
     p2 = Process(target = func2(driver))
     p2.start()
     p3= Process(target=func3(driver))
     p3.start()

是什么原因？如何同时打开3个标签并将不同的任务分配给不同的标签？
