[Ubuntu-BD] bitwise right shift (>>)

[Kabbo Sarker]

I didn't know what it is. Just learnt it. It shifts the bits. For 
example (in python shell):
3 >> 1 # 00 00 00 11 moves 1 bit right 00 00 00 00 01
#Output: 1

3 << 1 # 00 00 00 11 moves 1 bit left 00 00 00 01 10
#Output: 6

# you can experiment with numbers:
1 << 1
#Output: 2

1 << 2
#Output: 4

1 << 3
#Output: 8

1 << 4
#Output: 16

512 >> 8
#Output: 2
