提示错误： TypeError: locator() takes 2 positional arguments but 3 were given

Question

封装：
from selenium import webdriver
 
def brower(type_):
    try:
        driver = getattr(webdriver, type_)()
    except:
        driver = webdriver.Chrome()
    return driver
 
class web_ui:
    # driver = webserver.Chrome()
    # 构造函数
    def __init__(self, type_):
        self.driver = brower(type_)
 
    # 打开url
    def open(self, url):
        self.driver.get(url)
 
    # 元素定位
    def locator(self, value):
        return self.driver.find_element(value)
 
    # 点击
    def click_(self, name, value):
        self.locator(name, value).click()
 
    # 输入
    def send_(self, name, value, txt):
        self.locator(name, value).send_keys(txt)
 
    # 退出
    def quit_(self):
        self.driver.quit()
 
    # 等待
    def sleep_(self, value=10):
        self.driver.implicitly_wait(value)


调用：
from selenium1.web_ui import Web_ui

web = Web_ui('Firefox')
web.open('http://www.baidu.com')
web.send_('id', 'kw','python')

Answer 1

1. 定义： self, value 2个参数
   def locator(self, value):

   return self.driver.find_element(value)
   

2. 调用：locator(name, value)，+ 默认的self参数，locator引用3参数 > 定义的2个参数
   def send_(self, name, value, txt):

    self.locator(name, value).send_keys(txt)
