student Brian Yi asked we're using Python 2 in this class but Python 3
Opiskelija Brian Yee kysyy, miksi käytämme Python 2:sta, vaikka on olemassa Python 3
exists are we is what we're learning outdated does it not help us in the real
opimmeko vanhaa tietoa? Onko siitä mitään hyötyä todellisuudessa?
world ok so fair enough question there there
Okei, ihan hyvä kysymys.
is a newer version of Python and almost
Pythonista on uudempi versio ja lähes kaikkeen, mitä opimme tällä kurssilla
everything that we've learned in this class it doesn't matter whether using Python or JavaScript or scheme or C or
ei vaikuta ohjelmoitko Pythonia, Javascriptiä, Schemeä, C:tä, Javaa
Java any programming language the basic
tai mitä tahansa muuta ohjelmointikieltä. Perusasiat, jotka olemme oppineet soveltuvat
concepts that we've learned really apply to all of those languages in the same
kaikkiin ohjelmointikieliin samalla tavalla.
way now developing skills as a programmer is useful to learn different
Kehittyäkseen ohjelmoijana on hyödyllistä oppia eri ohjelmointikieliä
languages and different languages have slightly different ways of doing things
ja eri ohjelmointikielillä asioita tehdään vähän eri tavalla
and we talked in the previous question
ja kuten edellisessä kysymyksessä, joka liittyi pythonisuuteen
about the pythonic way being the best way to do something in Python to really
paras tapa tehdä jotakin Pythonilla on ohjelmoida
take advantage of the design and the style that the Python programmers to
sillä tyylillä, jota Python-ohjelmoijat odottavat.
expect Python 3 is different from Python 2 and in some ways it's not that
Python 3 eroaa joiltakin osin Python 2:sta, mutta se ei eroa kovin paljon.
different so almost everything that you've written in this class would work
Lähes kaikki mitä olet tehnyt tällä kurssilla toimii
in Python 3 and would be the same way to
Python 3:ssa ja tehtäisiin samalla tavalla Python 3:ssa,
write it in Python 3 some things would and most code today's Python 2 is still used more widely than Python 3 there's
mutta ei kaikki. Tällä hetkellä Python 2 on vielä yleisempi kuin Python 3.
some incompatibilities in Python 3 that mean it's very hard to move libraries
Python 3:ssa on joitakin yhteensopimattomuuksia, jotka hankaloittavat kirjastojen päivittämistä
that were written for Python 2 to work
Python 2:sta Python 3:een
in Python 3 and the infrastructure that we're using is all working in Python 2
ja infrastruktuuri jota käytämme, toimii Python 2:ssa
not in Python 3 so that's the real reason that we use Python 2 for this
mutta ei Python 3:ssa. Tästä syystä käytämme Python 2:ta
class instead of Python 3 but
tällä luenolla Python 3:n sijaan.
essentially everything that you've
Mutta periaatteessa kaikki jota olet oppinut on samaa
learned would be the same would be very easy to transfer if you start writing
ja helposti siirrettävissä Python 3:lle.
Python 3 code some things will be a little different probably the most
Jotkin asiat ovat vähän erilaisia ja todennäköisesti kaikkein huomattavin eroavaisuus on
notable thing that would be different is
että print-komento toimii eri tavalla.
print would work differently so the code that you've written that uses print would not work in Python 3 you'd have to
Koodisi, joka käyttää print-komentoa ei toimisi Python 3:ssa
add extra parentheses around it but
Sinun täytyy lisätä sulkeet.
otherwise everything would really be the
Mutta muuten kaikki on todellakin samaa
same there's no concepts that would be different it's just a matter of different things defined slightly
Käsitteet eivät muutu, jotkin asiat vain
differently in different languages
määritellään eri tavalla eri kielissä.
