in older projects you might have worked with older versions of thenumpylibrary. Some old code, that once worked beautifully, might stop working once you update its version. Perhaps parts ofnumpyare no longer compatible with other parts of your program. Creating virtual environments prevents...
运行args描述的命令,等待命令完成后返回returncode属性。 timeout参数会传递Popen.wait()。如果超过timeout,子进程将会被kill掉,并再次等待。子进程被终止后会抛出TimeoutExpired异常。 Eg: >>>returncode = subprocess.call('exit 1', shell=True) print(returncode)# 输出1 ...
导入pathlib的典型方式是使用语句from pathlib import Path。因为Path类是pathlib中使用最频繁的类,这可以让你输入Path,而不是pathlib.Path。您可以将文件夹或文件名的字符串传递给Path()来创建该文件夹或文件名的Path对象。只要表达式中最左边的对象是一个Path对象,就可以使用/操作符将Path对象或字符串连接在一起。
