How can you convert an iterator object into a generator function in Python?

To turn an iterator object into a generator function in Python, you can write a function with the keyword yield that uses the iterator internally to get elements sequentially and returns them one by one.

Example:

def iterator_to_generator(iterator):
    for item in iterator:
        yield item

# Usage example
my_list = [1, 2, 3]
my_iter = iter(my_list)
gen = iterator_to_generator(my_iter)

for value in gen:
    print(value)

Thus, the generator function wraps the iterator and allows iteration over it using yield.
