'NoneType' object is not callable in Jupyter












0















I am trying to run simple commands in python using Jupyter, which takes some inputs from console and computes based on the value. However, a simple "input" command which used to work fine is not working now.



Command:




num1 = input("Enter a number")




Exception:



---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-121-ff2dc32ed727> in <module>()
----> 1 num1 = input("Enter a number")

TypeError: 'NoneType' object is not callable

    Somehow or other you have redefined input. Instead of being the builtin function it is now None.

  • Yes, that had happened. I used "del" to delete the variable input and now everything works fine.
