I’m currently doing Dr. Charles Severence’s lessons on FreeCodeCamp to try to learn Python3. I’m on lesson exercise 02_03 and confused about multiplying floating-point and integer values.
The goal is to write a Python program multiplying hours worked by pay rate to come up with a pay quantity.
This is the code I wrote:
h = input("Enter hours: ")
r = input("Enter pay rate: ")
p = float(h) * r
I got a traceback error, and the video said the correct way to solve said error was change Line 3 from p = float(h) * r
to p = float(h) * float(r)
.
However, what I’m confused about is why would I need to change r
to a floating-point value when it’s already a floating-point value (since it’d be a currency value like 5.00 or something once I typed it in per the input()
command*?
What am I missing here?
*I can’t remember: are the individual commands in a python line called “commands”?
Edit: Wrote plus signs in my post here instead of asterisks. Fixed.
EDIT: Thanks to @Labna@lemmy.world and @woop_woop@lemmy.world. I thought that the input()
function was a string until the end-user types something in upon being prompted, and then becomes a floating-point value or integer value (or stays a string) according to what was typed.
This is incorrect: the value is a string regardless of what is typed unless it is then converted to another type.
I work as a cashier at a dead-end retail store in a town of 5000. (Seriously, the closest reasonably large city is like 30 minutes away.) So I don’t think there’s much of an opportunity at my current workplace. Haha.
But you still make an excellent point and it sounds like a good starting-off point. Thank you!
