Python 循环的写法很直接：defslow_loop(doc_list, word, tag): n_out = 0for doc in doc_list:for tok in doc:if tok.lower_ == word and tok.tag_ == tag: n_out += 1return n_outdefmain_nlp_slow(doc_list): n_out = slow_loop(doc_list, 'run', 'NN') print(n_out...
Example 1 - Using range function to loop n times The example here iterates over the range of numbers from 1 to 10 and prints its value. However, if it reaches the number divisible by 5, it will break the loop. Note that in this case, the statement inside the else block will not be...
1for loopIs an iterator based loop, which steps through the items of iterable objects like lists, tuples, string and executes a piece of code repeatedly for a number of times, based on the number of items in that iterable object. 2while loopExecutes a block of statements repeatedly as lon...

下图展示了这个常见的架构,主线程使用事件循环(Event Loop)处理用户和系统输入。需要长时间处理的任务和会阻塞 GUI 的任务会被移交给后台或 worker 线程: 一个该并行架构的实际案例可以是一个图片应用。当我们将数码相机或手机连接到电脑上时,图片应用会进行一系列动作,同时它的用户界面要保持交互。例如,应用要将图片...
