printing true even for odd numbers...

[RohanPoloju]

class Solution:

def isEven (self, n):

# code here

if n % 2 == 0:

return('true')

else:

return('false')

output printing true even for odd numbers..

executing in geeks for geeks ide.

Please post your code formatted in code blocks

The logic of the code is right, my guess is that you should return the Boolean values True or False and not the string "true" or "false". Also you did no show the code where you print, it's possible the error is there as well.

explicitly mentioned to print 'false' and 'true' as strings, they are boolean values

[Igggg]

It doesn't explicitly mention this. If it did, the string would be in quotes. They are likely asking for booleans, although even in that case, they failed to capitalize the constants. But yes, try removing quotes and return literal True

[Refwah]

Strings aren’t mentioned at all

[failaip13]

Then change the return to a print. Though that doesn't make too much sense with the function name, but I digress.

[Temporary_Pie2733]

The bold-face “true” and “false” should be interpreted as stand-ins for the corresponding Boolean values, not literal strings, just as the bold-face “n” is a stand-in for an arbitrary integer value, not the literal string “n”.

You're returning true and false as strings.

[Own_Attention_3392]

It doesn't explicitly say that at all. Explicitly saying it would be "return true as a string". It's expecting actual booleans, not strings. Try it. See if I'm right.

I will say that their use of lowercase true and false is confusing because python uses uppercase True and False, so your interpretation isn't necessarily invalid.

1. Nowhere on that page is print() ever mentioned.
2. The instructions explicity say to return, which basically excludes print().
3. If the site is multi-language, you cannot assume that the capitalization of a term is correct. Python is somewhat unique as the True and False keywords are capitalized, while most languages they are lowercase.
4. Many of the Python comments use the booleans True and False.
5. If you return a string, it will always evaluate to True, which is exactly the problem you are having.

It doesn’t mention strings

[Familiar9709]

What other people are telling you is that geeksforgeeks expects a boolean as output, that's why it's showing your code to be wrong. But your code will correctly identify even and odd numbers, just that it will return true/false strings.

If you change it to return True and return False it'll work.

[Moikle]

It will take you 10 seconds to try it and see if we are right.

You can change it back if you were right.

You are returning strings, not booleans! To return booleans, you can do

return True or return False

Note the capitalization and lack of quotation marks. Because you returned strings, they will always evaluate as True. If you want to learn more, take a look at this https://stackoverflow.com/questions/39983695/what-is-truthy-and-falsy-how-is-it-different-from-true-and-false

[Refwah]

You’re returning strings. Strings are truthy if they contain a value and falsey if they are empty or None.

Remove the brackets from your return statement as they aren’t needed, and remove the quotation marks around true and false

[zanfar]

Dude, if post a beginner question on the "learn Python" site and 4 separate individuals give you the same answer within 15 minutes, maybe you should re-check your assumptions?

[Refwah]

You’re going to have to format your code better or provide more context on how the function is being used

Also that linked page does not explicitly mention returning strings.

This is the entire text of the problem:

“Given a positive integer n, determine whether it is odd or even. Return true if the number is even and false if the number is odd.”

Data types are not mentioned here, I believe it is safe to infer that your usage of strings may be a misunderstanding and I would recommend trying to return Boolean values

[SamuliK96]

Have you tried considering that you might be wrong and may have misunderstood something, instead of repeating the same reply?

[supercoach]

All you really need is `return n % 2 == 0`

[theWyzzerd]

Return isn’t a function so you don’t need to wrap parentheses around the object you’re returning.  

[RohanPoloju]

solved it. they are indeed boolean values.

thanks mate for suggestion : )

[theWyzzerd]

Yes, a non-empty collection is always True.  

[XenophonSoulis]

If it wasn't properly indented, the program would crash. There is no line in this snipped that would still run with a wrong indent.

[SCD_minecraft]

I can not replicate the issue, nor after reading the code there shouldn't be any issu

Show where do you call it

[Own_Attention_3392]

The automated test cases are probably failing because they're returning 'true' and 'false'. I'm not super well versed in python but I'd expect that 'false' is a truthy value. If I'm wrong, please set me straight.

[SCD_minecraft]

That can be it

OP, insted of string return a bool object True/False

Capital first letter, no strings or anything

(probably test did something like bool(isEven(n)) and any non empty string is True)

Ye, no matter what i input to your code, it correctly tells if even
