Python Functions - Introduction

​Learning Target: I can write my own functions, use them in my code, explain why they make my programs easier to manage, and fix mistakes in function definitions.

Yeah

I've been tryna call
I've been on my own for long enough
Maybe you can show me how to love, maybe
I'm goin' through withdrawals
You don't even have to do too much
You can turn me on with just a touch, baby

I look around and
Sin City's cold and empty (oh)
No one's around to judge me (oh)
I can't see clearly when you're gone

I said, ooh, I'm blinded by the lights
No, I can't sleep until I feel your touch
I said, ooh, I'm drowning in the night
Oh, when I'm like this, you're the one I trust
(Hey, hey, hey)

I'm running out of time
'Cause I can see the sun light up the sky
So I hit the road in overdrive, baby, oh

The city's cold and empty (oh)
No one's around to judge me (oh)
I can't see clearly when you're gone

I said, ooh, I'm blinded by the lights
No, I can't sleep until I feel your touch
I said, ooh, I'm drowning in the night
Oh, when I'm like this, you're the one I trust

I'm just walking by to let you know (by to let you know)
I could never say it on the phone (say it on the phone)
Will never let you go this time (ooh)

I said, ooh, I'm blinded by the lights
No, I can't sleep until I feel your touch
(Hey, hey, hey)
(Hey, hey, hey)

I said, ooh, I'm blinded by the lights
No, I can't sleep until I feel your touch

Fill in the Blanks

Functions are really powerful programming constructs because they let us _____ ______​

​ of code

that we have already written. This helps us manage the complexity of our programs because it can ​

______ ​ the amount of code that we need to write​ . It also helps make our programs easier to __________ ​

​

and consequently maintain, because functionality is more clearly separated within our programs.

#COMPLETE THE FUNCTION DEFINITION

def calculate_profit( _ ):

# Calculate the profit using the formula P(x)

profit = (-8* (x ** 2)) + (3200 * x) - 16000

# Return the final calculated profit

return

#COMPLETE THE FUNCTION CALL

apartmentsrented1 = 30

_____________ = calculate_profit(_________________)

print("If",apartmentsrented1," apartments are rented, the profit is: $",profitresult1)

Function Requirements

1. Function Name: calculate_total_cost

2. Parameters: The function must accept exactly two parameters in the following order:

   • quantity (an integer representing the number of items).

   • unit_price (a float representing the cost of one item).

3. Calculation: The function must return the result of quantity * unit_price.

You are working as a junior developer for "SupplyChain Solutions," a company that provides inventory tracking software to small businesses. A core requirement of their application is the ability to instantly calculate the total cost of any given purchase order.

-The total cost is calculated by multiplying the quantity of items ordered by the unit price of that item.

Your task is to implement a reusable Python function that performs this critical calculation.
