Hey everybody --

I just wanted to send out a few notes about homework. I saw some common issues while grading, and wanted to give some reminders, tips, and tricks which I think are going to be pretty useful for your upcoming homework assignment.

Commenting

When commenting method headers, make sure you always do the following:

1. Describe what the method does (without describing what the code does)
2. Describe what every parameter does

Well, first off, the problem states that our method should accept a second BankAccount, not a String. So, our method header will look like:

public void transfer(BankAccount other, double amount)

I think this was the main thing you were stuck with -- getting the correct type signature. Apart from that, it looks like you were on the right track.

Then, we can get to the business of writing the code. If the balance in the current bank account is too small, we'll just terminate early:

For reference, here is your original code:

#!/usr/bin/env python

def encrypt (raw_string, shift):
    encrypted_string = ""
    for letter in raw_string:

Introduction

The primary lesson I want to go over today is [separation of concerns][soc].

When coding, there are often many different tasks or components that make up the entire program. For example, gathering user input, displaying data, running algorithms, and storing data are all examples of different "tasks" or "concerns".

One problem many beginning coders have is a tendency to "blur" these concerns together, and end up writing functions that try and do too many things at once.
