I recently started coding with Python( my first language) and it sure seems like one hell of a ride.
Hopefully I would get to learn from more learned coders.

Here is a sample question

In Nigeria, mobile phone numbers begin with the digit 0 and can contain any digits(0,1,2,3,4,5,6,7,8,9). The first 4 digits of the numbers
determine the particular network provider. For instance, GlobalCom Nigeria Limited numbers can
begin with 0805, MTN 0803 and Airtel 0802 etc. The mobile phone numbers must
have 11 digits all together. For instance, this is my MTN number:
0813 568 3431.
Write a program that can calculate the total number of possible subscribers of
MTN numbers that begin with 0813 and print out all the numbers.

HINT
total_digits = 11: total digits of each number
digits_needed = 7: digits needed to complete 0813 to 11-digit numbers.
available_digits = 10: i.e 0,1,2,3,4,5,6,7,8,9
Note: Computer CPU has some limitations, some may not print out all the numbers. Instead of printing out all the numbers in computers with low
processor speed and RAM. Consider printing out numbers that meet some certain conditions like numbers that ends with "3431" like my number
in the question. But your program must be able to count all the total available numbers in "0813" even though it may not print them all out to the console.
Also you have to make the program flexible such that you can easily change the lines for instance, you change can "0813" to "0806", "0803", "0805", "0902" etc or even make it start with country code "+234813". Goodluck.

Boss, I'm still a learner sir.
Can use mtn.prefChanger() to change 0813.
I forgot converting mtn.prefChanger argument to string...i did in earlier version.
Can use mtn.gen() to generate numbers and ending of choice. I chose 4457.
If no number is specified, it prints without condition.

live4dgospel:
Your program uses built-in method to arrange the numbers. You should write codes that generates the numbers, don't use "arrange"

progeek37:
Good. Can you do this without the pre-knowledge that the sum of the numbers is 10**7? That's the essence of the question, the same thing you did here can be done using Python range but such solution is trivial.

IamTeen:
This?

I used mtnNumbers.setPrefix() function to switch from 0813 and mtnNumbers.setLastNumbers() to change the numbers ending.
mtnNumbers.printNumbers() function did the printing.

live4dgospel:
Yes, I think this is good.

Nice!

Okay. Please after solving it consider sharing the screenshots of the sample run of the program. Thanks
