hi all help about boolean

[akaw3]

hi all im new to programming and its logic and i ve read that if length of string longer than 256 and less than -5 the cache memory does nt save it and it turns false. like this:

a = 256
a is 256
True

a = 257
a is 257
False

but when i run this code on vs code it turns all true but when i run this code on idle it turns like this.
