rand.randrange returning 'builtin_function_or_method' object has no attribute 'randrange'

I have the problem that rand.randrange won't work. From searching the internet I found that this is from a different file that is named random. If I do

print(random, type(random))

then I get the following result

<built-in method random_sample of mtrand.RandomState object at 0x111f70b40> <class 'builtin_function_or_method'>

My imports are the following: import matplotlib.pyplot as plt import random as rand from pylab import *

I use a mac and python 3.7.1. Could somebody tell me what I need to do and how to fix this issue?
