Why do I have to insert "print" to calculate sth?

Question

I.e. 2+2, so, u should insert in the IDE the text that follows "print(2+2)" but sometimes if I just insert in the IDE "2+2" I get the same result.

Yeah, I'm quite noob but that's weird

Thanks in advance :-)

Answer 1

When you are in ide or in editor then you need to write
print(2+2)
And when you are in interpret session or running in shell then you only need to write
2+2 and you got the same result.
