我正在尝试使用pip安装软件包,它会抛出错误.

我用过的命令,

它显示的错误,

Exception:

我正在尝试使用 Selenium 登录 gmail。在新的 gmail 登录中，首先输入您的电子邮件 ID，然后在下一个页面中输入您的密码。电子邮件页面和密码页面的URL，两者都是不同的。因此，当我在其中传递密码 URL 时，driver.get它会重新加载页面，如果您在不输入密码的情况下刷新 URL，它会重定向到电子邮件页面。因此，它缺少密码字段选择器。current_url仍然是以前的网址，即电子邮件页面的网址。这是我的代码。我正在使用 chrome 驱动程序和 python 2.X

import os
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

chromedriver = "/Documents/chromedriver" # Path to chrome-driver
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)

# Email insert 

driver.get("https://accounts.google.com/signin/v2/identifier?service=mail&passive=true&rm=false&continue=https%3A%2F%2Fmail.google.com%2Fmail%2F&ss=1&scc=1&ltmpl=default&ltmplcache=2&emr=1&osid=1&flowName=GlifWebSignIn&flowEntry=ServiceLogin")  #URL of email page
username = driver.find_element_by_id("identifierId")
username.send_keys("myemail")
driver.find_element_by_id("identifierNext").click()


# Password Insert 

driver.get("https://accounts.google.com/signin/v2/identifier?service=mail&passive=true&rm=false&continue=https%3A%2F%2Fmail.google.com%2Fmail%2F&ss=1&scc=1&ltmpl=default&ltmplcache=2&emr=1&osid=1&flowName=GlifWebSignIn&flowEntry=ServiceLogin")  # URL of password page
password = driver.find_element_by_id("password")
password.send_keys("mypassword")
driver.find_element_by_id("passwordNext").click()

#driver.quit()

我有一本字典.我只是想加入这些价值观.这是字典: -

d = {'x': 1, 'y': 2, 'z': 3} 

我的预期输出是123 (它应该是123而没有任何排序)

我正在使用的代码: -

d = {'x': 1, 'y': 2, 'z': 3} 
test = ' '.join(d.values())
print test

它显示错误: -

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    test = ' '.join(d.values())
TypeError: sequence item 0: expected string, int found

我正在使用python 2.x.
