print(“in if __name__ == \“__main__\” block”)在上面的代码中，可以运行 python print_hello.py in if __name__ == \“__main__\” block 如果用python来执行该文件，那么in if __name__ == “__main__” 条件就会满足，就会打印出 in if __name__ == “__main__” block语句。
The last two lines of the script are the conditional block that checks__name__and runsmain()if theifstatement isTrue. Now, you can run the whole processing pipeline from the command line, as shown below: Shell $python3best_practices.pyThis is my file to demonstrate best practices.Reading...
By checking the value of name using theif __name__ == '__main__'condition, you can control which code is executed in different scenarios. If the condition is True, then the indented code block following the conditional statement is executed, while if it is False, the code block is ski...
当kernel一直等到数据准备好了,它就会将数据从kernel中拷贝到用户内存,然后kernel返回结果,用户进程才解除block的状态,重新运行起来。 非阻塞I/O: Linux下,可以通过设置socket使其变为non-blocking。当对一个non-blocking socket执行读操作时,流程是这样子: 当用户进程发出read操作时,如果kernel中的数据才没有准备好,...
1)如果block使用默认值,且没有设置timeout(单位秒),消息列队如果已经没有空间可写入,此时程序将被阻塞(停在写入状态),直到从消息列队腾出空间为止,如果设置了timeout,则会等待timeout秒,若还没空间,则抛出"Queue.Full"异常; 2)如果block值为False,消息列队如果没有空间可写入,则会立刻抛出"Queue.Full"异常; ...
ida python 去除间接跳转块 有了间接跳转块代码的分析,就可以开始写ida python 愉快的去花了。 从整个trace文件中搜索 push {r0, r1, lr} 发现共有8097处 汇编代码,且下方紧跟着的就是 ldr r0, [pc, #4]。 那就可以根据这两行汇编,作为间接跳转块的...
