这是我打开Chrome的代码:

from selenium import webdriver 
driver=webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')

运行程序时出错:

Traceback (most recent call last):
  File "C:/Users/Imran/PycharmProjects/webscrapping/WF Item.py", line 6, in <module>
    driver = webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')

我想使用在变量中定义的正则表达式模式

我有一个包含正则表达式的变量模式，即

pattern = "/^[0-9+]{7}-[0-9+]{1}$/"

并将此模式发送到 Joi 模块并要确认

module.exports = {
    save: {
        body: {
          match: Joi.string().regex(pattern).required
        }
     }
 }

如果我使用这个，我知道验证工作

module.exports = {
        save: {
            body: {
              match: Joi.string().regex(/^[0-9+]{7}-[0-9+]{1}$/).required
            }
         }
     }

但就我而言，每次正则表达式都会有所不同。所以我不能使用上面的正则表达式模式
