What are the ways to translate number systems?

Question

Informatics

Is there any universal way to translate numbers from one number system to another? Or for the speed of translation, some kind of easy way. Thank you.

Answer 1

There are standard and bicycle ways.
For example, the standard python function int, which takes a string argument, can take a base as an optional second:
The bicycle method is also simple:

def to_str(n, radix):
    l = []
    while n:
        n, d = divmod(n, radix)
        l.append("0123456789ABC...Z"[d])
    return ''.join(reversed(l))

print(to_str(12345, 10))

Which one is universal, which one is light - decide for yourself.
