What are bitwise shift (bit-shift) operators and how do they work?
...ed, in memory, as a series of bits. For example, the number 6 stored as a 32-bit int would be:
00000000 00000000 00000000 00000110
Shifting this bit pattern to the left one position (6 << 1) would result in the number 12:
00000000 00000000 00000000 00001100
As you can see, the digits have s...

Fast way of counting non-zero bits in positive integer
...dapting Óscar's and Adam's solutions to process the integer in 64-bit and 32-bit chunks, respectively. Both were at least ten times slower than bin(n).count("1") (the 32-bit version took about half again as much time).
On the other hand, gmpy popcount() took about 1/20th of the time of bin(n).coun...
