[主程式管理篇] 如何獲取主程式資訊 - tsungjung411/python-study GitHub Wiki

關鍵字：

top-level, top-parent, main, reference, self, itself, hasattr, module

範例1

globals()

範例2

for k, v in dict(globals()).items():
    print('{k}: {v}'.format(k=k, v=v))

__name__: __main__
__doc__: None
__package__: None
__loader__: <class '_frozen_importlib.BuiltinImporter'>
__spec__: None
__annotations__: {}
__builtins__: <module 'builtins' (built-in)>

範例3：動態調用頂層函數(dynamically call a top-level function)

def say_hello():
    print('Hello!')

funcation_name = 'say_hello'
globals()[funcation_name]()
