![What Does an Empty Return in Python Mean? [Duplicate]](https://docuprint.cloud68.co/uploads/what-does-an-empty-return-in-python_1200.jpg)
When looking through Python code on GitHub, I've seen several examples of a return with no value. For example:
if hasattr(self, 'moved_away'):
return
# and here code continues
What does the empty return mean?

It means it will return None. You could remove the return and it would still return None because all functions that don't specify a return value in python will by default return None.
In this particular case it means the code will go no further if the object has the attribute 'moved_away', without the return any code below would be evaluated even if the if statement evaluated to True.
So you can think of it as being similar to a break statement in a loop when you have a condition you want to exit the loop on, without the break the code would continue to be evaluated.
if hasattr(self, 'moved_away'): # if this is True we return/end the function
return
# if previous statement was False we start executing code from here
return exits the current function.
So, here it will stop the execution & return None.
