# Input from the command line
import sys

B = sys.argv[2]
C = sys.argv[3]

# Your code goes here
num = A * (B + C/3

# Outputs
print ( num

Alright, hi folks. I'm trying to finish my homework assignment and I've gotta do so:

4. 2. Fix challenge 2

Note: Your arguments are strings unless they are converted into some other type. In this challenge, we are using decimals (float) rather than integers (int) for our type. So, you will need to tell Python to treat the variables as floating point decimal numbers by putting float(variable) in at the correct times.

I've tried

print(float(num))

and even

num = (float(A*(B+C/3))

but I get:
"Traceback (most recent call last):
File "fix2.py", line 9, in
num = A * (B + C/3)
TypeError: unsupported operand type(s) for /: 'str' and 'int'"

What am I doing wrong?

You can use

num = float(A) * (float(B) + float(C)/3)

RE: Homework help please - ichabod801 - Sep-08-2019

Or you can do it when you first read the value: A = float(sys.argv[1]).
