Is it possible to append elements to a python generator?
I'm currently trying to get all images from a set of disorganized folders and write them to a new directory. To get the files, I'm using os.walk() which returns a list of image files in a single directory. While I can make a generator out of this single list, I don't know how to combine all these lists into one single generator. Any help would be much appreciated.

Generator objects have two additional methods, return() and throw() , that are similar to next() .
Python provides a generator to create your own iterator function. A generator is a special type of function which does not return a single value, instead, it returns an iterator object with a sequence of values. In a generator function, a yield statement is used rather than a return statement.
Generators are memory efficient since they only require memory for the one value they yield. Generators are lazy: they only yield values when explicitly asked.
You are looking for itertools.chain. It will combine multiple iterables into a single one, like this:
>>> import itertools >>> for i in itertools.chain([1,2,3], [4,5,6]): ... print(i) ... 1 2 3 4 5 6 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
