WSTable 'list' object is not callable code example

Example: TypeError: 'list' object is not callable

What does "TypeError: 'list' object is not callable" mean?

To put it simply, the reason the error is occurring is because you 
re-assigned the builtin name list in the script.

Python has a builtin named list.
If you reassign it to some value(eg. list = [1,2,3,4,5]) then it causes 
problems in python.
