How can i generate random variables using np.random.zipf for a given range of values?

I have a given price range and i had used random uniform to get random generated random results from it. How can i introduce np.random.zipf to do the same ?

i have tried the following :

a = np.random.zipf((randint(1, 6000000)), size=None)
print(a)

But it seems to be providing no return values, and it keeps running the code without any termination

order_total_price_range1 = round(random.uniform(850, 560000), 5)
order_total_price_range2 = round(random.uniform(850, 560000), 5)

I expected to get max and min values from the zipf distribution, but currently not getting any results returned.
