How to test multiple variables against a value?
...
You misunderstand how boolean em>x m>pressions work; they don't work like an English sentence and guess that you are talking about the same comparison for all names here. You are looking for:
if m>x m> == 1 or y == 1 or z == 1:
m>x m> and y are otherwise evaluated on ...
How can you do anything useful without mutable state?
...ples and say "Here, don't you see" -- but if you don't understand the syntam>x m> and underlying principles, then your eyes just glaze over. From your point of view, it looks as if I'm doing the same thing as an imperative language, but just setting up all kinds of boundaries to purposefully make program...
How can I view the source code for a function?
...risked
"Non-visible functions are asterisked" means the function is not em>x m>ported from its package's namespace. You can still view its source code via the ::: function (i.e. stats:::t.ts), or by using getAnywhere(). getAnywhere() is useful because you don't have to know which package the function...
How do you calculate the average of a set of circular data? [closed]
I want to calculate the average of a set of circular data. For em>x m>ample, I might have several samples from the reading of a compass. The problem of course is how to deal with the wraparound. The same algorithm might be useful for a clockface.

How to split/partition a dataset into training and test datasets for, e.g., cross validation?

training, test = m>x m>[:80,:], m>x m>[80:,:]
or

Custom HTTP headers : naming conventions

The recommendation is was to start their name with "m>X m>-". E.g. m>X m>-Forwarded-For, m>X m>-Requested-With. This is also mentioned in a.o. section 5 of RFC 2047.
Update 1: On June 2011, the first IETF draft was posted to deprecate the recommendation of using the "m>X m>-" prefim>x m> for non-st...

List of lists changes reflected across sublists unem>x m>pectedly
...
When you write [m>x m>]*3 you get, essentially, the list [m>x m>, m>x m>, m>x m>]. That is, a list with 3 references to the same m>x m>. When you then modify this single m>x m> it is visible via all three references to it:
m>x m> = [1] * 4
l = [m>x m>] * 3
print(f"id(m>x m>): {id(m>x m>)}"...
