Python code runs as script and in ipython, but throws error in jupyter-notebook [duplicate]

I am trying to run a snippet of my code in Jupyter notebook, but it's failing. However the same snippet runs as script as well as a python script.

code :

import asyncio

async def a_square(x):
    print(f'Asynchronously squaring {x}!')
    return x ** 2


asyncio.run(a_square(2))

Error in Jupyter

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)
<ipython-input-4-e2feaf9936d2> in <module>
      5     return x ** 2
      6 
----> 7 asyncio.run(a_square(2))

/usr/lib/python3.8/asyncio/runners.py in run(main, debug)
     31     """
     32     if events._get_running_loop() is not None:
---> 33         raise RuntimeError(
     34             "asyncio.run() cannot be called from a running event loop")
     35 

RuntimeError: asyncio.run() cannot be called from a running event loop

Python path, version are same for all. The following statements gave same output for Jupyter, Ipython as well as when executed from script.

import sys
print(sys.executable)
print(sys.version)

output :
