TypeError: 'NoneType' object is not iterable

The error message “TypeError: ‘NoneType’ object is not iterable” typically occurs when you try to iterate over a variable that has a value of None.

In other words, if you have a line like:

  1. for i in my_variable:
  2. # do something with i

And my_variable happens to be None, then you’ll get the error.

To fix this, make sure your variable my_variable is not None before trying to iterate over it.
