Python 中的位元運算(Bitwise Operations)詳解:新手指南
在 Python 編程中,位元運算是一種直接對二進位數位(bits)進行操作的技巧。 雖然在高階語言中不常見,但位元運算在許多領域,如系統編程、加密、網路編程和性能優化中,扮演著關鍵角色。 對於剛開始學習 Python 的新手來說,理解位元運算的概念和用法,將大大拓展你的編程技能。 本文將深入 ...

Python Bitwise Operators - GeeksforGeeks
Python bitwise operators are used to perform bitwise calculations on integers. The integers are first converted into binary and then operations are performed on each bit or corresponding pair of bits, hence the name bitwise operators. The result is then returned in

Bitwise Operators in Python
Python bitwise operators are defined for the following built-in data types: int bool set and frozenset dict (since Python 3.9) It’s not a widely known fact, but bitwise operators can perform operations from set algebra, such as union, intersection, and symmetric.

BitwiseOperators - Python Wiki
One more point: Python allows operator overloading, so some classes may be written to allow the bitwise operators, but with some other meaning. For instance, operations on the Python set and frozenset types have specific meanings for | (union), & (intersection) and ^ (symmetric difference).

How do I manipulate bits in Python? - Stack Overflow
Bitwise operations on Python ints work much like in C. The &, | and ^ operators in Python work just like in C. The ~ operator works as for a signed integer in C; that is, ~x computes -x-1. You have to be somewhat careful with left shifts, since Python integers aren ...

Bitwise Operators in Python (AND, OR, XOR, NOT, SHIFT)
Bitwise NOT, invert: ~ The ~ operator yields the bitwise inversion. The bitwise inversion of x is defined as -(x+1). 6. Expressions - Unary arithmetic and bitwise operations — Python 3.11.3 documentation If the input value x is regarded as two's complement and all.
