I have completed the project however for the two test statements I get an output of none for one of them and I don’t know why. Link to task:

``````
def cost_g_shipping(weight):
if (weight <= 2):
price_pound = 1.50
elif weight <= 6:
price_per_pound = 3.00
elif weight <= 10:
price_per_pound = 4.00
else:
price_per_pound = 4.75

return 20 + (price_per_pound * weight)

def cost_d_shipping(weight):

if (weight <= 2):
price_per_pound = 4.50
elif weight <= 6:
price_per_pound = 9.00
elif weight <= 10:
price_per_pound = 12.00
else:
price_per_pound = 14.25

return price_per_pound * weight
#print(cost_d_shipping(1.5))

def cheapest_method(weight):
ground_cost = cost_g_shipping(weight)
drone_cost = cost_d_shipping(weight)

if (ground_cost < premium_cost) and (ground_cost < drone_cost):
method = 'Standard Ground'
cost = ground_cost

method = 'Drone'
cost = drone_cost

else:
print('The cheapest shipping method for you is \$%.2f with %s Shipping.'
%(cost, method))
print(cheapest_method(41.5))
print(cheapest_method(4.8))

``````

For the input of 4.8lbs it prints ‘None’, it should print \$34.40. Where did I go wrong?

Hi @immortaldarknorth - welcome to the forum.

Take a look at the indentation level of your print call:

``````    print('The cheapest shipping method for you is \$%.2f with %s Shipping.'
%(cost, method))
``````

When is that code going to be run, and how is that going to affect the output of your function in each of the various cases in your `if-else` structure?
