I wonder.... the indentation in Ruby is optional for clearer code.. or mandatory like in Phython...

Answer 1

It's optional. Or rather it's a stylistic choice.
Ruby only looks for the line breaks.
But, I think, it's very important for the readability of the code!

Answer 2

I think its optional,but i would recommend clear code anyway

Answer 3

Agreed completely.. it makes the code clearer to read...

Answer 4

By indenting you make your code Readable thus easy to understand and debug,just in case an error occurs.
