Free variables are returned by locals() when it is called in function blocks, but not in class blocks. 说明: 1. 函数功能返回当前作用域内的局部变量和其值组成的字典,与globals函数类似(返回全局变量) >>> locals() {'__package__': None, '__loader__': <class '_frozen_importlib.Builtin...
使用 import module,模块自身被导入,但是它保持着自已的名字空间,这就是为什么你需要使用模块名来访问它的函数或属性(module.function)的原因。但是使用 from module import,实际上是从另一个模块中将指定的函数和属性导入到你自己的名字空间,这就是为什么你可以直接访问它们却不需要引用它们所来源的模块的原因。 local...

In the above example, we attempted to change the value of thepresentvariable inside thelocalsPresent()function using thelocals()method. Whilelocals()returns a dictionary representing the current local symbol table, modifying the dictionary does not change the actual value of the local variables in ...
File "5.py", line 16, in aaaa print a NameError: global name 'a' is not defined 1. 2. 3. 4. 5. 6. 7. 8. 程序运行报错了! 但是在第二次print locals()很清楚能够看到, 局部空间是已经有那些变量了, 其中也有变量a并且值也为1...
