How do I fix my code and make it print what I need it to?

I keep getting this error in my code and I don't know how to fix it:

line 27, in Northeast_Analysis
    light_count = np.count_nonzero((5,  northeast_packages) & (northeast_packages,  50))
TypeError: unsupported operand type(s) for &: 'tuple' and 'tuple'
>>> c

This is my code so far:

# This program analyzes We-Truck-It package delivery information and
# generates truck purchase type recommendations for each of the
# We-Truck-It company U.S. Delivery regions.

#import the numpy.py library for random number generation and data analysis

import numpy as np

# store the number of packages delivered in the northeast and northwest
# in the variables ne_num and nw_num

ne_num = 60831
nw_num = 50629

def Northeast_Analysis():

# Recommend the best truck purchase type for the Northeast Region

# use the numpy.py random number function to simulate
# package weights for the Northeast

northeast_packages = np.random.uniform(low=5.0, high=150, size=(ne_num,))

# use numpy.py to determine the number of packages within the recommended
# ranges for the light, medium and heavy truck types

light_count = np.count_nonzero((5,  northeast_packages) & (northeast_packages,  50))
medium_count = np.count_nonzero((51,  northeast_packages) & (northeast_packages,  100))
heavy_count = np.count_nonzero((101,  northeast_packages) & (northeast_packages,  150))

# print the number of trucks within the recommended package delivery weight
# ranges for light, medium and heavy trucks
# print values with two decimal points

print (' ')
print (' *** Northeast truck purchase analysis')
print (' ')
print ('number of Northeast packages in the light truck weight range:')
print (format(light_count, '.2f'))

print ('number of Northeast packages in the medium truck weight range:')
print (format(medium_count, '.2f'))

print ('number of Northeast packages in the heavy truck weight range:')
print (format(heavy_count, '.2f'))

# Generate a truck purchase recommendation based on the most common package weight

if   (light_count,  medium_count) and (light_count,  heavy_count):
    message = ('The light truck is the best purchase for the Northeast region')

    message = ('The medium truck is the best purchase for the Northeast region')

print (' ')

print (message)

# Call the functions to analyze the Northeast and Northwest delivery information

Northeast_Analysis()
Northwest_Analysis()

What I have tried:

I have tried to fix the errors but Im stuck. In the long run I am supposed to:

Create a function similar to the Northeast_Analysis() and Northwest_Analysis () functions to determine the recommended truck purchase type for the Southeast region. Assume this region delivers 44,000 packages in a year.

Create a se_num variable to hold the number of packages shipped by the Southeast region.

Use the numpy.py random number function to simulate package weights for the 44,000 packages shipped in the Northeast.

Use the np.random.uniform(low=5.0, high=150, size=(se_num,)) to randomly generate the 44,000 packages using a minimum package weight of 5.0 and maximum package weight of 150 pounds.

Use the np.count function to count the number of packages for the recommended package delivery weight for light, medium and heavy trucks.

Print out the number of packages that fall within the weight ranges for each delivery truck.

Print the recommended truck type to purchase for the Southeast.
