Difference Between np.random.uniform() and uniform() using built-in python packages

Question

I'm using np.random.uniform() to generate a number in a class. Surprisingly, when I run the code, I can't see any expected changes in my results. On the other hand, when I use uniform() from python built-in packages, I see the changes in my results and that's obviously normal.

Are they really the same or is there anything tricky in their implementation?

Thank you in advance!
