if i < 5:
small_nums.append(i)
The first example is declarative because we do not specify any "implementation details" of building the ...

B-Tree vs Hash Table
...than with a tree algorithm (O(1) instead of log(n)), but you cannot select ranges (everything in between x and y).
Tree algorithms support this in Log(n) whereas hash indexes can result in a full table scan O(n).
Also the constant overhead of hash indexes is usually bigger (which is no factor in the...

Fast way of counting non-zero bits in positive integer
...You can generate it at runtime:
counts = bytes(bin(x).count("1") for x in range(256)) # py2: use bytearray
Or just define it literally:
counts = (b'\x00\x01\x01\x02\x01\x02\x02\x03\x01\x02\x02\x03\x02\x03\x03\x04'
