Many times when you wish to bash a problem with 'programmingbash', changing base of a number is needed. Of course we can use wolfram, but it'll get irritating if there are too many numbers.
So here, $\color{#3D99F6}{\text{Python comes to our help!}}$
I've written this program in Python 2.7, for getting a decimal number in some other base...
($\text{cb}$ stands for change_base )
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 

First I had written that using the while
loop for $n$, got pretty bad...
It left zeroes that come in between, and also I couldn't efficiently assign Alphabets to digits greater than 9.
But now, I've made it shorter and efficient with the while
loop for $y$.
Here's the program for the other way, changing a number from other way, into decimal!
1 2 3 4 5 6 7 8 9 10 11 12 

I want to know if there are any improvements that you can spot, thanks!

Top Newest@Aditya Raut Can you please give me some further sources than Codecademy. I guess you also learnt from there at first. But I want to know if there is any "advanced" source like CA. The course at CA is quite limited.

I didn't learn from codeacademy, I learnt from 12 books and mainly, experimenting...

That is great. Experimenting is the best way to learn. Especially in programming. I learn programming the same way.

There is a typo in cb(n,m) line 7. It should be
return '1'*n

The standard way to convert a string in base $b$ to an integer is
int(string,b)
,by the wayLog in to reply
What is just happening!
So all I did was nothing but an $\text{exercise}$ of no real use, just use
int(str,b)
..... Why does this keep happening with me!Thank you btw, for telling this amazing shortcut, where'd you learn that?

I don't exactly remember but I guess stackoverflow.
