**Automation** is undoubtedly one of the most coveted skills a programmer can possess. Automation is typically used for tasks that are **repetitive, boring, time-consuming** , or otherwise **inefficient** without the use of a script.

With **web automat** you can easily **create a bot to perform different tasks** on the web, for instance, to monitor competing hotel rates across the Internet and determine the best price.

Personally, I have always found **logging into my email** fairly repetitive and boring, so for the sake of a simple example to get you guys **started with web automation** , let’s implement an **automated Python script** to **log in with a single click** to a Gmail account. ((Source:hongkiat)

##### Installation and Setup

In this tutorial we are going to use the **following tools** :

1. [Python](https://www.python.org/) programming language
2. [Google Chrome](https://www.google.com/chrome/) browser
3. [Selenium](https://www.selenium.dev/) browser automation toolkit
4. [Chrome Driver](https://sites.google.com/a/chromium.org/chromedriver/) web driver for Chrome

For our program, we will be using the [Python](https://www.python.org/) programming language, specifically **version 2.7.11**. It is critical that we install a **fairly new version of Python 2** because it comes with **PIP** , which will allow us to install third-party packages and frameworks that we will need to automate our scripts.

Once installed, **restart your computer** for the changes to take effect. Use the command `pip install selenium` to add the **[Selenium](https://www.selenium.dev/download/) web automation toolkit** to Python. Selenium will allow us to programmatically scroll, copy text, fill forms and click buttons.

Finally download the **[Selenium Chrome Driver](https://sites.google.com/a/chromium.org/chromedriver/) executable**, which will **open Google Chrome** as needed to perform our automated tasks. The Chrome Driver is simply a way to open Google Chrome (which should already be installed) to **access standard browser operations programmatically**.

Simply download the most recent ZIP file from [here](https://sites.google.com/a/chromium.org/chromedriver/downloads), extract the `chromedriver.exe` executable, and place the executable in any directory. Be sure to make note of where your executable is, because **we will need it once we get started**.

##### Starting the Program

As aforementioned, we’ll be using the **[Selenium](https://www.selenium.dev/) web automation framework** in order to **log in programmatically**. The first order of business is to **import every module** we’ll be needing from the Selenium Python library which we installed ealier with PIP.

Let’s open [IDLE](https://docs.python.org/3/library/idle.html) or another code editor, **create a new Python file** with `.py` extension, and **import the following modules** :

```auto
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

```

Next, we’ll **create two strings** that represent our **username and password** for the email account. Pay attention to capitalization, especially in your password string.

```auto
usernameStr = 'putYourUsernameHere'
passwordStr = 'putYourPasswordHere'

```

Now that we have everything set up in order to start the login process, we need to actually instruct a browser window to **open Google Chrome** , and **navigate to Gmail’s login page**.

If you haven’t done so already, make sure your Python script is **saved in the same location as the `chromedriver.exe` executable** we extracted earlier.

```auto
browser = webdriver.Chrome()
browser.get(('https://accounts.google.com/ServiceLogin?'
'service=mail&continue=https://mail.google'
'.com/mail/#identifier'))

```

##### Finding Our Element

We’ve successfully gotten the browser to open Gmail, but now we need to **find the input fields** on the web page, into which we can **enter our username and password**.

We can do this easily using the built-in Chrome Developer Tools. We only need to right-click on the input fields, and select the “Inspect” menu.

 ![image](https://onehack.st/uploads/default/original/3X/d/8/d8b261ed30275160ba1166266fd2b7f106b64b9e.jpeg)

Now it’s just a matter of **using HTML `id` attributes** to find the elements programmatically.

In the code below, we’re simply **searching for the username input field by `id`** , and **filling it** with the desired text. Then we’re **searching for the Next button** which transitions with a quick animation before prompting us for the password.

The `send_keys()` and `click()` commands do exactly as their names suggest — `send_keys()` **simulates keypresses** in the desired element, and `click()` **simulates a mouse click**.

```auto
# fill in username and hit the next button
username = browser.find_element_by_id('Email')
username.send_keys(usernameStr)
nextButton = browser.find_element_by_id('next')
nextButton.click()

```

We can **do the same thing** for the password input field, as well as for the Sign In button. However, these two items appear on the page **only _after_ an animated transition**.

That said, we need the program to **wait a few seconds** before resuming its search for elements. For the most part, this stage of code is no different from the previous one. We simply have to instruct the browser to **wait a maximum of 10 seconds** before locating the password entry.

```auto
# wait for transition then continue to fill items
password = WebDriverWait(browser, 10).until(
EC.presence_of_element_located((By.ID, 'Passwd')))
password.send_keys(passwordStr)
 
signInButton = browser.find_element_by_id('signIn')
signInButton.click()

```

##### Final Words

You’ve just finished **creating a bot** that visits a web page, enters your username and password, and successfully sign you in, **automating the whole process** to a single click. I know this was a simple demonstration, but the possibilities are endless.

On that same note, **be careful** of how you use this skill. Some people use bots and automated scripts to enter sweepstakes thousands of times, completely disregarding terms and conditions. Others use them for more malicious intentions.

Just be sure to use automation purposefully and carefully, because it really is a **much needed skill** in the programming community! ([Source](https://github.com/hongkiat/autologinbot/))

**Happy learning!**
