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. https://code.sololearn.com/c9Dhz8R0K2hD/?ref=app

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)

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.

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. https://realpython.com/python-bitwise-operators/
