Here's pretty much the only place where you can buy Mark Summerfield's "Python 3" book in Argentina: Cúspide.
It costs $372.50 in pesos which is about $94 in dollars.
Oh, and you have to go to a book store to pick it up, or add shipping.
How much does it cost to buy that book in england and have it shipped to your door? $16. That's a whooping 17% of the local cost.
And no, it won't pay import taxes, because books are exempt.
And did I mention that the english version came out a year earlier?
So, if you don't learn english, you pay almost 6 times for the book, and wait a year.
Any programmer that doesn't know enough english is a third class citizen.
