so i can run it?

[old fable]

c=0;h=0;twe=0;two=0
for i in range(len(a)):#range
    if a[i] % 2 == 0:#check if even
        c+=1;#count of even
        if c==2:
            two=a[i]
            #2nd even number
        
    for k in range(i+1,-1):
        if a[k] % 2==0:
            h+=1
    if h==1:
        twe=a[i]
        
   
print(two,twe)
         ```

Hey @old fable!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

a=[1,2,3,4,5,6,7,8,9,10,11,12]
c=0;h=0;twe=0;two=0
for i in range(len(a)):#range
    if a[i] % 2 == 0:#check if even
        c+=1;#count of even
        if c==2:
            two=a[i]
            #2nd even number
        
    for k in range(i+1,-1):
        if a[k] % 2==0:
            h+=1
    if h==1:
        twe=a[i]
        
   
print(two,twe)
            ```

i did a little change and its hsowing 4

but is the 2nd last even logic correct?

[magic salmon]

I think a better aproach would be to start reading the list from the front store the second even and break
Than do the same from the end

[magic salmon]

I don't think so there are simpler ways for sure

[old fable]

so ill check for the 2nd last even from the end?

[old fable]

okay

[magic salmon]

Looks like the second if behaved like an elif for no reason

[magic salmon]

Yes iterate from the end of the list backwoards

[old fable]

ohh

i need to make another for loop

thank you!!

[magic salmon]

c=0
for i in list:
  if i%2==0:
    if c ==1:
      a=i
      break
    c=1

Than the same with the list reversed

[magic salmon]

Stuff in the second is double indented

[old fable]

somehow still worked 🤣

[old fable]

oh ok

[magic salmon]

Also add a break to the second too

[magic salmon]

Its the same with a litle order change

[old fable]

okay

thank you so much!

[magic salmon]

And bc u dont use i for else than indexing u could iter the list and
list[::-1]

The second is same as reversed(list)

[old fable]

i havent got to that part yet ig

[old fable]

oh yeah
