strange question

Question

Can anyone explain me this? Ive looked into Google but found nothing

x=5
print(x>>2) # result is 1
print(x<<2) # result is 20
print(x>>2<<x) # result is 32

i dont get it. What is >> or << ???

Answer 1

>> shifts the bits of the binary version of 5 to the right, and << to the left.

so x >> 2 shifts the bits 2 positions to the right.

Answer 2

you need to understand binary a bit....

decimal 5 is 00000101in binary
5>>2 is 00000001 which is 1 in decimal
5<<2 is 00010100 thats 16+4 =20
(5>>2)<<5 is 1<<5 , thats 00100000 which is 32 in decimal.

Answer 3

A >> n means "divide A by 2, n times" :
A/(2^n)
A << n means "multiply A by 2, n times":
A* (2^n)
