Python脚本文件是两种中间文件格式中的一种。设备通过运行Python脚本来下载版本文件。 Python脚本文件的文件名必须以“.py”作为后缀名,格式如Python脚本文件示例所示。详细脚本文件解释请见Python脚本文件解释。 Python脚本文件示例 该脚本文件仅作为样例,支持SFTP协议进行文件传输,用户可以根据实际开局场景进行修改。
If we try and copy food to a new variable meal, the values of food will be copied into meal, but so will the reference of food. meal = food Directly equating one object to another will make the new object point to the previous one; this means that the two variables will reference ...

entry_points=dict( console_scripts=["my-script = package.module:function"], ) 在某些情况下,--console-scripts参数是不必要的。如上例所示,如果只有一个控制台脚本入口点,那么它就是隐式的。否则,如果有一个与包同名的控制台脚本,则使用该脚本。这占了相当多的情况,也就是说这个论证往往是多余的。
某些类实例,这些类的dict属性值或 [__getstate__()]()函数的返回值可以被打包(详情参阅打包类实例这一段) 对于不能序列化的类型,如lambda函数,使用pickle模块时则会抛出PicklingError`` 异常。 序列化过程: (1)从对象提取所有属性,并将属性转化为名值对 ...
