First, install Python
https://www.python.org/downloads/
Python verify whether the installation was successful. Open the Windows command prompt (cmd), enter python, carriage return
Note: During the installation need to check: "Add Python 3.x to PATH", if not checked, it is necessary after the installation is complete, the Python installation directory (eg: C: \ Python37) added to the PATH environment variable below.
Second, install selenium
1, a first installation method: Pycharm installation Selenium, command: pip install selenium
2, the second installation method: Locate Pycharm in the File -> Settings -> Project -> Project Interpreter, click on the + sign in the upper right corner, search selenium, click on the bottom Install Package to install selenium.
3, selenium verify whether the installation was successful
Third, the first selenium + python program
Above have been successfully download the corresponding version of the browser chromedriver drive. Here we have to write the first selenium + python program. I will describe two methods for reference study.
method one:
1, the downloaded chromedriver.exe (2.46) into (copied or moved) to the installation directory of chrome (chrome installation path generally follows, C: \ Program Files (x86) \ Google \ Chrome \ Application), as shown below below:
2, the test code is as follows:
from selenium.webdriver import Chrome
import time
driver = Chrome("C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe")
driver.get('https://www.baidu.com')
print(driver.title)
time.sleep(5) driver.quit()
方法二：
1、将下载的chromedriver.exe（2.46）放到（复制或移动）至Python的安装目录下，与python.exe文件相同目录下。查看Python的安装目录（cmd输入命令where python）。如下图所示：
2、测试代码如下：
from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.get('https://www.baidu.com/')
print(driver.title)
time.sleep(5) driver.quit()
两种方法运行结果一样，运行结果如下图所示：
注：如下载chromedriver版本不对或没有将chromedriver.exe文件拷贝至相应的目录下，则会出现：“selenium.common.exception.WebDriverException:Message:'chromedriver' executable needs to be in Path”报错。
当你运行demo程序，成功出现百度首页时恭喜你并打印出“百度一下，你就知道”，恭喜你，已经成功运行第一个selenium+python测试程序。
