如果python script.py,__name__直接被默认为__main__ 如果import script,__name__会被设为__script__ 所以把代码放到if __name__ == '__main__'意思是直接跑脚本的时候会直接调用(通常是实例化各种类),如果被import的话我不想被调用的代码;一般import都是工具库或者封装好的函数

__import__()会抛出ImportError而非ValueError,这通常是在相对导入超出其顶级包时发生。 Python获取在命令行(例如:python3 script.py)上指定的脚本文件名的绝对路径,__main__模块的__file__属性变为绝对路径,而非相对路径。通过os.chdir()更改当前目录后,这些路径仍然有效。副作用是,在这种情况下,回溯还会显示模...
在未安装libc++.so的全新 Linux 计算机上,使用 Java 或外部语言运行sp_execute_external_script(SPEES) 查询会失败,因为commonlauncher.so未能加载libc++.so。 例如: SQL EXECUTEsp_execute_external_script @language= N'Java', @script = N'JavaTestPackage.PassThrough', @parallel=0, @inp...
Microsoft.Azure.WebJobs.Script.Workers.WorkerProcessExitException:使用代碼 137 結束的 Python 當使用SIGKILL訊號的作業系統強制終止 Python 函數應用程式時,就會發生此錯誤。 此訊號通常表示 Python 流程中的記憶體不足錯誤。 Azure Functions 平台有服務限制,將會終止任何超過此限制的函數應用程式。

If you’re tinkering with a script like this, then you’ll want subprocess to fail early and loudly.CalledProcessError for Non-Zero Exit Code If a process returns an exit code that isn’t zero, you should interpret that as a failed process. Contrary to what you might expect, the Python...
exit(0) if not os.access(filename, os.R_OK): print ‘[-] ‘ + filename + ‘ access denied.’ exit(0) print ‘[+] Reading Vulnerabilities From: ‘ + filename To verify our code, we initially try to read a file that does not exist, which causes our script to print an error....
You will notice that in the Python code, the Javascript function is called before the browser window is even started - any early calls like this are queued up and then sent once the websocket has been established. Return values While we want to think of our code as comprising a single app...
