覆盖导入，显示导入模块的模块的名称

Question

  

可能重复：
  know filename:line_no where an import to my_module was made

我想知道哪些模块正在导入我的示例模块“foo”：

foo.py

# pseudocode, this should be triggered when "foo" is imported
on_import():
    print "foo is imported by module X"

bar.py

# this should print "foo is imported by module bar"
import foo 

如何实现此行为？

Answer 1

@Wooble你是对的

以下是know filename:line_no where an import to my_module was made

的解决方案

import inspect
last_frame = inspect.stack()[1]
print 'Module imported from file:line_no = %s:%i' % last_frame[1:3]
