How can you convert a regular function into a generator in Python?

To convert a regular function into a generator in Python, you need to use the keyword yield instead of return. This allows the function to return values one at a time, maintaining its state between calls.

Example of converting a function into a generator:

def count_up_to(n):
    i = 1
    while i <= n:
        yield i  # return the value but do not terminate the function
        i += 1

for number in count_up_to(5):
    print(number)

This generator will sequentially output numbers from 1 to 5 without creating the entire list in memory at once.
