how does the built-in function: int(s, base) works?

Question

I was going thru the use of this function but want alter to figure out how it works...

for e.g. int("A9",13) will give the result: 139
and, int("B7", 17) will give .. 194

so, could some one pls. explain how come this actually happened..

Many Thanks,
Adarsh :)

Answer 1

This function has two arguments. The first argument is how the number is displayed, the second one: the base the number is written in. From examples given in question: A9 in base 13 is 139 and B7 in base 17 is 194. I hope I helped.

Answer 2

One more thing. Attemting to put ciphers from wrong base eg 9 in base 8 raises ValueError.

Answer 3

yeah that helped and I also got some help from an online converter.
That would be a tedious task to calculate manually... thanks to Python.

have a great time ahead.
