“m>x m> not in y” or “not m>x m> in y”
...tor, which could be applied to a in b just as easily as any other boolean em>x m>pression, whereas not in was a separate operator for convenience and clarity.
The disassembly above was revealing! It seems that while not obviously is a logical negation operator, the form not a in b is special cased so th...
“git rm --cached m>x m>” vs “git reset head -- m>x m>”?
...
There are three places where a file, say, can be - the tree, the indem>x m> and the working copy. When you just add a file to a folder, you are adding it to the working copy.

I received some tem>x m>t that is encoded, but I don't know what charset was used. Is there a way to determine the encoding of a tem>x m>t file using Python? How can I detect the encoding/codepage of a tem>x m>t file deals with C#.

I want to get the type of a variable at runtime
...ble" is always present, and can be passed around as a type parameter. For em>x m>ample:
val m>x m> = 5
def f[T](v: T) = v
f(m>x m>) // T is Int, the type of m>x m>
But depending on what you want to do, that won't help you. For instance, may want not to know what is the type of the variable, but to know if the type o...

What is “entropy and information gain”?
...
I assume entropy was mentioned in the contem>x m>t of building decision trees.
To illustrate, imagine the task of learning to classify first-names into male/female groups. That is given a list of names each labeled with either m or f, we want to learn a model that fits th...
Sort a list of tuples by 2nd item (integer value) [duplicate]
...
sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda m>x m>: m>x m>[1])
key should be a function that identifies how to retrieve the comparable element from your data structure. In your case, it is the second element of the tuple, so we access [1].
For optimization, see jamylak's res...
