Bitwise Operators in Python – Real Python

WebNov 14, 2024 · The Python programming language provides arithmetic operators that perform addition, subtraction, multiplication, and division. It works the same as basic mathematics.

If we performed an arithmetic shift right on the value 16 in Python and shifted it right 1 then our output would be 8. If we shifted right twice our output would be 4 as we are essentially dividing by 4. >>> 16 >> 1 8 >>> 16 >> 2 4

WebMay 3, 2015 · Such functions are often desirable because they do not require extra memory to operate. Define shift_left, a function that takes a list and shifts each element in the list to the left by n indices. If elements start ”falling off” on the left, they are placed back on the right. NOTE: you may assume that n is a non-negative integer.
