Introduction

Sal has a shipping company and wants to help her customers find the lowest-cost method of shipping their packages. So, it's my job to write the program to help her customers decide between 3 shipping methods:

1. drone shipping
2. ground shipping,
3. premium ground shipping

Shipping Cost

Drone Shipping

Package Weight (lbs)	Price / Pound ($ / lb)	Flat Fee ($)
less than or equal to 2	4.50	0.00
more than 2, less than or equal to 6	9.00	0.00
more than 6, less than or equal to 10	12.00	0.00
more than 10	14.25	0.00

Ground Shipping

Package Weight (lbs)	Price / Pound ($ / lb)	Flat Fee ($)
less than or equal to 2	1.50	20.00
more than 2, less than or equal to 6	3.00	20.00
more than 6, less than or equal to 10	4.00	20.00
more than 10	4.75	20.00

Premium Ground Shipping = $125.00

Technologies

• Python 3
• VSCode

Sources

The inspiration for this project was Codecademy's Python 3: Control Flow project called Sal's Shipping.

They provided example code of how to complete the job.

Extra Info

A lot is different from Codecademy's practice project.

• About the README:
  • The Shipping Cost content was added to this README file programmatically
    • because why would I type tables out in 5 minutes when I could spend much, much more time figuring out how to write a file-handling program to add the tables for me?
  • Need to look into the error handling for the file-handling program
• About the program to help Sal & her customers:
  • It is currently set to print the results to the terminal
    • it'll likely remain that way for a long time since I'd rather spend more time with Big O at the moment
  • Challenged myself to try syntax that's newer to me
    • there are likely parts of the program that you'd wish were more readable
    • in a few months from now, I'll probably wish the same
  • It is simplified to a function that will take the package weight as an argument
    • could've written the return/print message a bit differently to better present the info to the customer
  • There are example function calls in the use_the_fxn file
    • the purpose of this file is to practice importing functions in Python
  • Need to verify the function's argument type
    • verify/sanitize user input
• Critique:
  • I'm open to criticism; very much want to improve rapidly
  • If you notice something weird, or unsafe, or have food for thought, please don't hesitate to let me know
