Very few other languages even *have* keyword arguments, so the nearest
you'll get is something like this, where it's actually being wrapped
up into a dict-like object.
Here are a few examples gleaned by skimming a single file in one of my projects:
r = requests.request(method, "https://api.twitch.tv/"; + endpoint,
params=params, data=data, headers={
"Accept": "application/vnd.twitchtv.v5+json",
"Client-ID": config.CLIENT_ID,
"Authorization": auth,
})
# Recursion (the token mess is scheduled for change anyway):
return query(endpoint, token="bearer" if token == "bearer" else "oauth",
method=method, params=params, data=data, auto_refresh=False)
# This pattern is VERY common. After doing the work, we pass a
# whole bunch of info to the template renderer.
return render_template("index.html",
twitter=twitter, username=user["display_name"],
channel=channel, channelid=channelid, error=error,
setups=database.list_setups(channelid),
sched_tz=sched_tz, schedule=schedule, sched_tweet=sched_tweet,
checklist=database.get_checklist(channelid),
timers=database.list_timers(channelid),
tweets=tweets,
)
# There are also cases where I *could* use kwargs, but I don't,
# because it would be clunkier in syntax. This mixes positional
# and keyword just so that I don't need channelid=channelid.
database.update_timer_details(channelid, id,
title=request.form["title"],
delta=parse_time(request.form["delta"]),
maxtime=parse_time(request.form["maxtime"]),
styling=request.form.get("styling", ""),
)
So yes, this definitely does happen in the real world. I think it
would be nice to have a shorthand syntax, but it's not a killer
feature. I'm +0.75 on adding this.
