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。

another_ref=my_list 减少引用:当引用该对象的变量被重新赋值或作用域结束时,引用计数会减少。如果引用计数变为0,则表示没有引用指向此对象,进入垃圾回收流程。 2.2.5 垃圾回收(Garbage Collection) Python使用引用计数为主,结合循环检测和标记-清除等技术进行垃圾回收。一旦对象的引用计数归零,且不存在循环引用的情况...
