 # Sal's Shipping Project python

For the project above, I have 2 questions:

1. how do I code so my print function spits out a dollar amount for numerical data in my code below?
ie. 125.00 prints to \$125.00

2. Can someone tell me why my data is printing NONE?
What is spits out :
53.6
6.75
Ground Shipping is Cheapest

34.4
None
38.0
None
9.0
None

def GS_weight_cost(weight):
if weight > 10.0:
return (20.00 + weight * 4.75)
elif (6.0 < weight <= 10.0):
return (20.00 + weight * 4.00)
elif (2.0 < weight <= 6.0):
return (20.00 + weight * 3.00)
else:
return(20.00 + weight * 1.50)

PS = 125.00

def DS_weight_cost(weight):
if weight > 10.0:
return (weight * 14.25)
elif (6.0 < weight <= 10.0):
return (weight * 12.00)
elif (2.0 < weight <= 6.0):
return (weight * 9.00)
else:
return(weight * 4.50)

def type(weight):
if (GS_weight_cost(weight) < DS_weight_cost(weight)) and (GS_weight_cost(weight) < 125.00):
return “Ground Shipping is Cheapest”
elif (DS_weight_cost(weight) < GS_weight_cost(weight)) and (DS_weight_cost(weight) < 125.00):
return “Drone Shipping is Cheapest”
else:

if type(weight) == “Ground Shipping is Cheapest”:
return print(GS_weight_cost(weight))
elif type(weight) == “Drone Shipping is Cheapest”:
return print(DS_weight_cost(weight))
else:

print (GS_weight_cost(8.4))
print (DS_weight_cost(1.5))
print(type(4.8))
print( )

When you ask a question, don’t forget to include a link to the exercise or project you’re dealing with!

If you want to have the best chances of getting a useful answer quickly, make sure you follow our guidelines about how to ask a good question. That way you’ll be helping everyone – helping people to answer your question and helping others who are stuck to find the question and answer! We can use formatting to print a character string representation…

``````>>> '\$%.2f' % 12.345
'\$12.35'
>>> '\$%.2f' % 12.0000
'\$12.00'
>>>
``````

Or using the Pythonic approach…

``````>>> '{:.2f}'.format(12.345)
'12.35'
>>>
``````

This is the answer to your other question. If you remove the print statement and just go with the return, it is printed at the caller. As it stands, the printing takes place before the return, and None is returned since `print` has no return.
