How can a number be less than 0 and more than 35 at the same time?

jsOP•10mo ago

i was trying to put less than 0 or greater than i thought that was the right one im used to just putting or

Angius•10mo ago

&& is and || is or

jsOP•10mo ago

on py either way though thats after line 2 and line 2

Angius•10mo ago

Or if you're used to Python, dpMark is < 0 or > 35

jsOP•10mo ago

doesnt let me input anything program jsut closes

Angius•10mo ago

You mean it closes before you enter anything, or after you type in something?

jsOP•10mo ago

before as soon as i run it and i dont get it i used the same parse line on my previous assignment 5 minutes ago and it worked only thing diff is variable name

Angius•10mo ago

I wonder if it runs a previous version of the project I have a suspicion that

Console.WriteLine(dpMark," is not a valid mark for the digital portfolio");

Console.WriteLine(dpMark," is not a valid mark for the digital portfolio");

prevents it from compiling

jsOP•10mo ago

yh thats it i removed dpMark and it works like it should

Angius•10mo ago

Console.WriteLine() with two params works like string.Format()

jsOP•10mo ago

up until thjen

Angius•10mo ago

So it expects the first param to be a template string

jsOP•10mo ago

i wasnt sure how to print that

Angius•10mo ago

And the rest to be params Use string interpolation $"{dpMark} is whatever"

jsOP•10mo ago

thank you so much bro 🙂 is there way to say and or

Angius•10mo ago

Wym "and or"

jsOP•10mo ago

ive got two conditions and if one or both of them are true i want it to do something

Angius•10mo ago

That's an or

why is it not letting me set moduleMark to 34 at the bottom everything else is fine i think but

jsOP•10mo ago

Angius•10mo ago

You already have moduleMark variable declared You cannot redeclare it

jsOP•10mo ago

can i not edit it

Angius•10mo ago

You can moduleMark = 34.0

jsOP•10mo ago

do i just remove double oh

Angius•10mo ago

Yes

jsOP•10mo ago

its working but i got the maths wrong somewhere 😭 my invalid mark lines work but if im putting all valid inputs in im getting an output score of 0 everytime 😭
