让我们假设有模块A，B，C：
A.py
import C
# do stuff
B.py
import C
# do stuff
C.py
print( "I am the C module and I am being imported by " + get_importer_name() )
然后，当运行A.py或B.py时，输出将为：
I am the C module and I am being imported by A
I am the C module and I am being imported by B
是否存在类似get_importer_name()函数的东西，它获取导入我的模块的名称（假设我是模块）？
