When I am trying to run this code one by one: I can run it without any error and login successfully

 Here is the code:
  import selenium
  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import Select
  from selenium.common.exceptions import NoSuchElementException
  baseurl = "http://www.gcrit.com/build3/admin/"
  username = "admin"
  password = "admin@123"
  xpaths = {'usernameTxtBox': '//input[@name="username"]', 'passwordTxtBox': '//input[@name="password"]', 'loginButton': '//button[@id="tdb1"]'}
  mydriver = webdriver.Chrome(executable_path=r"C:mypathForseleniumchromedriver.exe")
  mydriver.get(baseurl)
  mydriver.find_element_by_xpath(xpaths['usernameTxtBox']).send_keys(username)
     mydriver.find_element_by_xpath(xpaths['passwordTxtBox']).send_keys(password)
  mydriver.find_element_by_xpath(xpaths['loginButton']).click()

My python file is saved in other file location. So I tried running the file in different ways

I ran in this way:   C:UsersmypathPython37python.exe "C:UsersmypathPythonScriptsSeleniumPractice.py"
Received this error message "SyntaxError: unexpected character after line continuation character"

Also, I tried to run in the way mentioned in this link "https://stackoverflow.com/questions/33905824/how-to-run-py-files-in-command-prompt-windows-7" but it is not working properly.
