我们可以使用位掩码(Bitmask)来检查和设置这些位。 # 定义标志位FLAG_A=0b0001# 1FLAG_B=0b0010# 2FLAG_C=0b0100# 4FLAG_D=0b1000# 8# 初始化状态status=0b0000# 所有标志位为0# 设置标志位status|=FLAG_A# 设置FLAG_Astatus|=FLAG_B# 设置FLAG_Bprint(f"当前状态:{bin(status)}")# 输出 0...
You can also use a bitmask to define Boolean flags that you can then pack on a bit field.There are a few common types of operations associated with bitmasks. You’ll take a quick look at some of them below.Getting a BitTo read the value of a particular bit on a given position, ...

The __invert__ method flips all bits in the value. Combined with other operators, it creates a powerful bitmask system. The inversion operation is particularly useful for creating mask complements or toggling flag states in bitmask operations. ...

Instead of using the modulo operator, you could alternatively truncate the hash code with a proper bitmask, which is how Python’s dict works internally. Note: To get consistent hash codes, set the PYTHONHASHSEED environment variable to 0 to disable hash randomization. Great! There’s a free...
Uses classes and subclasses to wrap some of the details of os.walk call usage to walk and search; testmask is an integer bitmask with 1 bit per available self-test; see also: visitor_*/.py subclasses use cases; frameworks should generally use__X pseudo private names, but all names here...
eventsis a bitmask of events ready on the socket (selectors.EVENT_READorselectors.EVENT_WRITEor both). If there are ready sockets when you callselect(), thenselect()returns immediately. Otherwise, it blocks until some of the registered sockets become ready. The OS will notifyselect()as it ...
