• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

i have no idea how to start all of those three

[finite moat]

1. tells you each step in order

• take input from user
• is even?
  • print event
• is odd?
  • print odd

[stable marsh]

can python automatically identify if an integer is odd/even?

[worthy beacon]

Yes

[stable marsh]

oh

[worthy beacon]

Use the % operator

[stable marsh]

to what

[worthy beacon]

Like this

4 % 2 = 0

So it's even

5 % 2 = 1
So it's odd

[stable marsh]

i mean how

or like where

[worthy beacon]

Okay so you input a number

[stable marsh]

whered u get those numbers

[worthy beacon]

I mean assign a number to a variable

[stable marsh]

done

[worthy beacon]

What's your variable

[stable marsh]

n

the user input

[worthy beacon]

So n = int(input("Enter number "))

[stable marsh]

n = int(input("Enter a value: "))

yes

[worthy beacon]

So then you use conditional statements

If n % 2 == 0:
print('The number is even')

[stable marsh]

what does the n % 2 == 0 mean

[worthy beacon]

Basically it means if n divided by 2 has 0 as a remainder

[stable marsh]

ohh

okay i get ir

[worthy beacon]

So add this to your code

And then use an else statement for if the number is odd

[stable marsh]

ive finished it

n = int(input("Enter a value: "))

if n % 2 ==0:
    print("The value is even")
else:
    print("The value is odd")
    
print("Thank You")```

thanm you!!

now for item 2

still dk how to starf

[finite moat]

"that asks for their exam score"

that's where you start 🙂

[stable marsh]

yeah i meant after that

[finite moat]

ok what do you think needs to be done then?

[stable marsh]

i dont know..

idk what to tell python what to do in order for me to execute the given problem

[finite moat]

break it down into small steps

so what's the overall goal for this one?

[stable marsh]

i was thinking earlier to assign a list of values to a variable, like A = 90 to 100 but idk how to do that and im sure there's an easier way than making a list manually

[finite moat]

ok i see. You could do that, but then it makes it so you basically have to type out every number from 0 to 100

you don't want that right

[stable marsh]

yes

do we use inequalities?

[finite moat]

yes

[stable marsh]

uhh how?

idk how to make it like n >= 90 but stops at 100

[finite moat]

so there are two conditions then

must be >= 90 but also <= 100

[stable marsh]

ohh

how do i write that in py

with the condition

[finite moat]

do you know what and, or, and not do?

[stable marsh]

no

[finite moat]

these are called boolean operators

however, there's a way to do this without needed them

you can do (psuedo code)

• if grade is >= 90
  • A
• otherwise, if grade is >= 80
  • B
• otherwise, if grade is >= 70
  • C

etc.

[stable marsh]

can you make an example writing that in py?

[finite moat]

no because then i'd just be giving you the answer

you'll want to use if and elif and else

[stable marsh]

oh right

what if the user types something > 100

is otherwise a primitive code?

[finite moat]

Well what does the question say about that?

[stable marsh]

oh, u just used it as a word to not give the answer?

okay what

currently 1am im just trying my best to stay awake

[stable marsh]

nvm i think i know

okay i did it

now i just wanna know how to tell my code anything >100 is an invalid input

nvm

just done it too

[finite moat]

Nice

[stable marsh]

n = float(input("Enter your grade: "))

if n > 100:
    print("invalid")
elif n >= 90:
    print("A")
elif n >= 80:
    print("B")
elif n >= 70:
    print("C")
elif n >= 60:
    print("D")
else:
    print("FAILED")```

[finite moat]

you don't need me 😄

[stable marsh]

thank you!!

[stable marsh]

well, i wouldnt have finished it without your help so thank you so much!!!

[finite moat]

no prob
