Side steps the GIL(Global Interpreter Lock) limitation of Python which allows only one thread to hold control of the Python interpreter 绕过了Python的GIL(全局解释器锁定)限制,它仅允许一个线程来控制Python解释器 Used for computation or CPU intensive programs 用于计算或CPU密集型程序 then what is Multi...
self.threadCondition.notify() # 一定要先调用notify()方法,在release()释放基本锁 self.threadCondition.release() # 可以理解为"通知"被wait的线程进入runnable状态,然后在它获得锁后开始运行 # 最后一定要release()释放锁,否则会导致死锁 def get(self): self.threadCondition.acquire() if len(self.shareObjec...
sorted(array,key=lambda item:item[0],reverse=True) 匿名函数lambda。 lambda的使用方法如下:lambda [arg1[,arg2,arg3,...,argn]] : expression 例如: >>> add = lambda x,y : x + y >>> add(1,2) 3 接下来分别介绍filter,map和reduce。 1、filter(bool_func,seq):map()函数的另一个版本,...

In the same comp.python.devel thread, Marc-André Lemburg states that the sys.setdefaultencoding must never be called by user code and the only values supported by CPython are 'ascii' in Python 2 and 'utf-8' in Python 3. 8 Curiously, the micro sign is considered a “compatibility ...
