Answer 1

Bitwise left shift: Shifts the bits of the number to the left and fills 0 on voids left as a result. Similar effect as of multiplying the number with some power of two.

Bitwise right shift: Shifts the bits of the number to the right and fills 0 on voids left as a result. Similar effect as of dividing the number with some power of two.

Answer 2

Cheenu💕™ There is not a built-in zero fill right shift operator in Python, but you can easily define your own zero_fill_right_shift function:

def zero_fill_right_shift(val, n):
return (val >> n) if val >= 0 else ((val + 0x100000000) >> n)
Then you can define your function:

def f(e, t):
return e << t or zero_fill_right_shift(e, 32 - t)

Vadivelan already seen burey's post!
✨Kårï§hmå✨ and what about ZERO-FILL RIGHT SHIFT (<<<)

Answer 6

Zero fill right shift >>> not <<< (arrows will point toward the direction of shift) Also known as Logical Right Shift.
The link I provided covers all 3 that you asked about and explains them well. Please read and if you have a more specific and explicit question afterwards, please feel free to ask it.
Doesn't matter that it is Java, works the same for most languages, including Python.

Answer 7

This explains in pretty good detail as to why Python doesn't have a zero fill right shift and how to work around it using similar techniques to what ✨Kårï§hmå✨ has posted.
