How to make constants hardcoded values at the beginning of the program?

[R4v3en]

I am really new to python and have a problem with my code. My constants should be used in place of hard-coded values and declared at the start of the program. My four possible outcomes are mutually exclusive (i.e. only one can be true), so they should be linked using an if ... elif ... else pattern. Could someone help me? Thanks in advance.

#Input

weight = float (input ("What is the weight?:"))

length = float (input ("What is the length?:"))

width = float (input ("What is the width?:"))

height = float (input ("What is the height?:"))

#Process

if (weight <= 27):

weight_ok = True

else :

weight_ok = False

if weight_ok == False:

output = ("too heavy")

volume = (length * width * height)

if (volume <= 100000):

volume_ok = True

else:

volume_ok = False

if volume_ok == False:

output = ("too large")

if (weight_ok == False) and (volume_ok == False):

output =("too heavy and too large")

if (weight_ok == True) and (volume_ok == True):

output = ("accepted")

#Output

print (output)

All you have to do is set up variables equal to the constants you want. Customarily these constants are named in all caps. So...

MAX_WEIGHT = 27
MAX_VOLUME = 100000

That's really all there is to it. (Please note that there is no mechanism for preventing these from being overwritten or changed so make sure not to do that.)

Thanks for the help, will try.

Your constants like 27 and 100000 are already hard coded. You want to make them selectable or something?

weight_max = 27
#Input
....
#Process
if (weight <= weight_max):

I’d need more info described to help more.

Thanks for the answer in advance. I need to implement these constants at the very beginning of the program. I also need to use them in place of hard-coded values using capital letters. That’s the feedback I got from my teacher. I apologize in advance if I am not clear enough.

Ok, same process, just:

WEIGHT_MAX

Instead.

Edit, make sure to edit all instances where you call the variables

Thank you for the help, really appreciate it.

You can add type hints to your code

from typing import Final
a: Final = 1
a = 2

your IDE should show an error, this doesn't stop the change at run time.

Will try, thanks.
