Why does Popen.communicate() return b'hi\n' instead of 'hi'?
...open("echo -n hi", \
shell=True, stdout=subprocess.PIPE).communicate()[0])
As for the b preceding the string it indicates that it is a byte sequence which is equivalent to a normal string in Python 2.6+

Value of i for (i == -i && i != 0) to return true in Java
....toBinaryString(Integer.MIN_VALUE));
you see that Integer.MIN_VALUE is
10000000000000000000000000000000
Taking the negative value is done by first swapping 0 and 1, which gives
01111111111111111111111111111111
and by adding 1, which gives
10000000000000000000000000000000
As you can see in...
JavaScript - cannot set property of undefined
... data: c
};
};
If you're in an environment that supports ES2015 features, you can use computed property names:
d = {
[a]: {
greetings: b,
data: c
}
};

Are lists thread-safe?

L[0] += 1
is not guaranteed to actually increase L[0] by one if another thread does the same thing, because += is not an atomic operation. (Very, very few operations in Python are actually atomic, because most of them can cau...
