python - 我在将列表作为自动化函数的字符串执行时遇到问题

Question

我有一个学校项目，我的程序必须执行此代码才能关注两个用户:

def followWithUsername(self):
    usernames = ['therock', 'justinbieber']
    self.driver.get('https://instagram.com/' + str(usernames) + '/')
    time.sleep(3)
    followButton = self.driver.find_element_by_css_selector('button')
    if (followButton.text != 'Following'):
        followButton.click()
        time.sleep(3)
    else:
        print("You are already following this user.")

我尝试了各种方法，但这不会将用户名彼此分开并一一执行

Answer 1

使用for循环:

def followWithUsername(self):
    usernames = ['therock', 'justinbieber']
    for name in usernames:
        self.driver.get('https://instagram.com/' + name + '/')
        time.sleep(3)
        followButton = self.driver.find_element_by_css_selector('button')
        if (followButton.text != 'Following'):
            followButton.click()
            time.sleep(3)
        else:
            print("You are already following this user.")
