Updated version of mass telephone number generator. | Short and sweet code.

 

https://blogofchamodh.blogspot.com/2020/10/generate-all-possible-phone-numbers.html

Here was the first version of the python script that generates crores of telephone numbers. But that script is complex and here is a simple version of the script.

Changes to the product() Function.

I wanted to generate all possible combinations of seven characters and put 7 lists as parameters of the product function but we can do it with only one list instead of seven lists. But you have to set the value 7 for the parameter "repeat" to tell the function you want a combination of seven characters 


product_a = product(['1','2','3','4','5','6','7','8','9','0'],repeat=7) 


And also you can change the product function as follows.

product_a = product('1234567890',repeat=7)



The above line of code does the same job but shortens our code too

You have another way to do this thing



import string
product_a = product(string.digits,repeat=7)

You can import String as shown above and replace our list parameter with string.digits
and it will give '0123456789' to our function to do the job

Let's talk about cryptography.

Have you ever heard of cryptography?  People write their diaries every day. For many of them, their diary is one of their best friends to whom they tell their every secret. What happens when someone else finds such a diary? That would freak out the dairy's owner for sure. Also, it might put their lives in danger. Wise men always hide their diaries so no one else finds it.  But legends hide their message so that only they can read what they wrote. So even if the diary is found by someone else, they cannot know the secrets. for example, I wrote this in my diary today.   P dyval h isvn wvza hivba jyfwavnyhwof avkhf Can you understand it? This is just a very primitive level of cryptography yet powerful enough to hide what I wrote from 90% of people. I will discuss this type of cryptography in the next blog post. The human used cryptography from the very beginning to share their messages in secret and conceal their inventions. As you may know, many people tried to find a recip...

Generate all possible phone numbers with Python | Generates Crores of Phone Numbers within minutes.

Recently,  I learned about itertools in python. Especially, about the functions permutations, combinations, and products and I tried to make a script that generates all phone numbers in our country. I bet your phone number is too on the list. let the hack begin!!! First, you need to install itertools in your computer  Simply open your terminal and type                sudo apt-get  install  -y python-more- itertools Then Write the code below from itertools import product file_name = "phonebook.txt" phonebook = open (file_name, 'a' ) prefixes = [ '+9471' ] product_a = product([ '1' , '2' , '3' , '4' , '5' , '6' , '7' , '8' , '9' , '0' ], [ '1' , '2' , '3' , '4' , '5' , '6' , '7' , '8' , '9' , '0' ], [ '1' , '2' , '3' , '4' , '5...
