Troubleshooting "TypeError: 'NoneType' object is not iterable"
When working with Python, you may encounter the error "TypeError: 'NoneType' object is not iterable." This error occurs when you try to iterate over a variable that is set to None. For instance:
for row in data: # Gives TypeError! print(row)
In such cases, the "data" variable is most likely assigned as None, which essentially means it's empty or has no value. To resolve this error, you can ensure that "data" is assigned a non-empty iterable object, such as a list or tuple, before attempting to iterate over it.
