Automating WhatsApp Web with Alright and Python
Alright is a python wrapper that helps you automate WhatsApp web using python, giving you the capability to send messages, images, video, and files to both saved and unsaved contacts without having to rescan the QR code every time.
Why Alright?
I was looking for a way to control and automate WhatsApp web with Python; I came across some very nice libraries and wrappers implementations, including:
So I tried
pywhatkit, a well crafted to be used, but its implementations require you to open a new browser tab and scan QR code every time you send a message, no matter if it’s the same person, which was a deal-breaker for using it.
I then tried
pywhatsapp,which is based onyowsupand require you to do some registration withyowsupbefore using it of which after a bit of googling, I got scared of having my number blocked. So I went for the next option.
I then went for WebWhatsapp-Wrapper. It has some good documentation and recent commits so I had hoped it is going to work. But It didn’t for me, and after having a couple of errors, I abandoned it to look for the next alternative.
PyWhatsapp by shauryauppal, which was more of a CLI tool than a wrapper, surprisingly worked. Its approach allows you to dynamically send WhatsApp messages to unsaved contacts without rescanning QR-code every time.
So what I did is refactoring the implementation of that tool to be more of a wrapper to easily allow people to run different scripts on top of it. Instead of just using it as a tool, I then thought of sharing the codebase with people who might struggle to do this as I did.

Basic Data Types in Python | Python Web Development For Beginners
At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Table of Contents hide
III Built-in data types in Python
Mutable objects
The Size and declared value and its sequence of the object can able to be modified called mutable objects.
Mutable Data Types are list, dict, set, byte array
Immutable objects
The Size and declared value and its sequence of the object can able to be modified.
Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.
id() and type() is used to know the Identity and data type of the object
a**=25+**85j
type**(a)**
output**:<class’complex’>**
b**={1:10,2:“Pinky”****}**
id**(b)**
output**:**238989244168
Built-in data types in Python
a**=str(“Hello python world”)****#str**
b**=int(18)****#int**
c**=float(20482.5)****#float**
d**=complex(5+85j)****#complex**
e**=list((“python”,“fast”,“growing”,“in”,2018))****#list**
f**=tuple((“python”,“easy”,“learning”))****#tuple**
g**=range(10)****#range**
h**=dict(name=“Vidu”,age=36)****#dict**
i**=set((“python”,“fast”,“growing”,“in”,2018))****#set**
j**=frozenset((“python”,“fast”,“growing”,“in”,2018))****#frozenset**
k**=bool(18)****#bool**
l**=bytes(8)****#bytes**
m**=bytearray(8)****#bytearray**
n**=memoryview(bytes(18))****#memoryview**
Numbers (int,Float,Complex)
Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.
#signed interger
age**=**18
print**(age)**
Output**:**18
Python supports 3 types of numeric data.
int (signed integers like 20, 2, 225, etc.)
float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)
complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)
A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).
String
The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.
# String Handling
‘Hello Python’
#single (') Quoted String
“Hello Python”
# Double (") Quoted String
“”“Hello Python”“”
‘’‘Hello Python’‘’
# triple (‘’') (“”") Quoted String
In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.
The operator “+” is used to concatenate strings and “*” is used to repeat the string.
“Hello”+“python”
output**:****‘Hello python’**
"python "*****2
'Output : Python python ’

Introduction to Browser Drivers in Selenium
Drivers in Selenium are a vital rather a must for Browser automation. Selenium library in Python or in any other programming language uses the particular Browser’s driver to control browsers with their actions, add functionality to it, and in all manipulate data (webpage) in it.
Contrary to the most common way of declaring a Browser’s Driver which is most common, but often may result in incompatibility issues. There are multiple ways (not so common) to install, initialize web drivers in your Python code.
Downloading the Drivers
The foremost point of error in Selenium occurs when the browser’s driver’s version doesn’t match with the browser’s version, for which compatibility issue arises. So, to start with, you must always use the driver with the same version as that of the Web Browser(Google Chrome, Mozilla Firefox, Apple Safari, or any other) which you intend to use for automation.
Downloading and installing Web Drivers is completely safe because these drivers are maintained by the Official Browser Companies and updated accordingly, for testing and automation purposes of their browser and webpages.
Check with your browser which you intend to automate for its version and download the driver from the below references accordingly:
| Web Browser | Driver Download Reference |
|---|---|
| Google Chrome/Chromium | Download |
| Mozilla Firefox | Download |
| Microsoft Edge | Download |
| Apple Safari | Already built-in |
Ways to use Drivers
Let’s now look at how we can use the selenium web drivers.
1. Entering the Direct Location
- The most popular method to use a web driver in Python Selenium code for browser automation. The reason for its popularity is the direct approach it uses, to define a driver in a script.
- This method requires manual downloading of the web driver.
Advantage: No need to care about lengthy setup or figuring out of Environment variable
Disadvantage: Makes the code less flexible and subject to manual changes for every update
driver = webdriver.Chrome('path/to/chromedriver")
driver = webdriver.Chrome('C://software/chromedriver.exe') #driver located at the specified location
driver = webdriver.Chrome('chromedriver.exe') #driver located in the same directory as of the python script file
#other way
service = Service(executable_path="/path/to/chromedriver")
driver = webdriver.Chrome(service=service)2. Environment Variable
- If you have tried the above-mentioned method, then you may have noticed how tiring it is to note/remember the location of your installed web driver in some directory of your computer.
- To tackle for this problem, we define the location or path of our driver in Environment Variable, once and for all. After successful definition, we do not require specifying the path location in our code, and we can code effortlessly.
- This method also requires manual installation of the driver, as you might have known this method is used for the issue of path variable.
Advantage: No hassle of specifying the path to the driver
Disadvantage: No update functionality
To set the Environment Path Variable, go to your command prompt and type in the following command:In place of “C:\WebDriver\bin” in the below command, use the path (install location) of the driver.
setx PATH "%PATH%;C:\WebDriver\bin"
If you find this way difficult, then you may search for Environment Variable in your Windows Start Menu and click open -“Edit the system environment variables“. After that, from the pop-up window select “Environment Variables” to open another pop-up window.
From the System Variables option, select open Path and now click on New to introduce a new path variable. Paste the location of your web driver in it, then OK, OK, and finally again OK, in all windows.
Environment Variable
3. Driver Manager
The last and probably the most useful method to use is the Web Driver in your Python code. On selecting, automatic updating in Web Browser, the device only updates the browser and not the installed driver, in this case upon execution of python script the code gives error for not equal versions of the browser and driver.
Advantage: No version compatibility issues and help easily switch between multiple browsers
Disadvantage: Maybe a bit difficult to set up for beginners
Install the driver manager
pip install webdriver-manager
Import the manager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager # --> for Chrome
#from webdriver_manager.firefox import GeckoDriverManager # --> for Firefox
Now as we have installed and imported the manager, we use it in our code like –
Use the install() method to get the location used by the manager and pass it into a loc_service class. This method informs about the location of the installed web driver by itself.
driver = webdriver.Chrome(ChromeDriverManager().install()) # --> for Chrome
#driver = webdriver.Firefox(executable_path=GeckoDriverManager().install()) #--> for Firefox
For any other browser, you may check the official GitHub repository of the driver manager software.
Conclusion
That’s it for the tutorial. Contrary to the popular methods of using the web drivers in Selenium, in this tutorial you learned about the other and maybe advantageous methods to perform the same.
