Let GPT run python code through the API

Is it possible for gpt4 to run python code?

I have the following little function and some small text:

def number_of_words(text):
    words = len(text.split())
    return words

I want GPT to ‘calculate’ the number of words of a text. Using the API. Is this possible?

More context: I am using gpt to create texts. I provide it with a lower and upper limit of words, e.g. 150-200 words. I want it to check whether the text it creates matches that requirement.
