Save default language of notebook into variable dynamically

[NLearn]

 For one of the requirements of project, I want to save default language of notebook into variable based on notebook path mentioned dynamically.

For eg: if first notebook given by user in widget is having default language as Python then variable value should set to "Python" and if notebook has been changed to Scala then variable value should to "Scala" automatically.

Hi Kaniz,

Thank you for sharing this information. Actually, in requirement, User is passing notebook path through widget which can be based on any language "Python", "SQL" and "Scala". but user is not providing information regarding language through any widget so, we have to open notebook manually to see in which language notebook has been created. 

So Is there any way that by knowing notebook path, we can get its default language and save in some variable?
