damn, did the same thing but replaced -1 with len(arr) -1, yours is much simpler lol

Wow.. I made mine way more complicated

This is an excelent use of String Slicing in Python

@fran496: no, but they're iterable objects that support indices, just like lists - except every element in a string is a single character. This means most of the syntax elements that can be used on lists can be used on strings as well.

_{^{except for mutating elements, you can do that with lists but not with strings}}

the kata specifies you don't have to deal with those

Efficiently done!

thanks, elegant !

Best Practice Indeed!

there are none less than 2 char

Simple as it is

thank you so much for explaining it !

damn...

ok but...what about the ones with less then 2 char? iam confused

There's a difference between the normal if: else: statement in Python and this. This is specifically what is called a "ternary operator", and it's a different syntax for a different operation (although it does similar things.

It's a bit of a shame that Python uses the same tokens if and else for both the conditional statement and the ternary operator - most languages don't, and it does make it confusing.

i dont understand how you can write a whole line with if AND else without any ':' and it works. everytime i try to do something like that i get an error. does someone has an idea of why that is please ?
