This function prints it self, can someone please explain how it works?

Print[ToString[#0][]]& []

Technically it prints Print[ToString[#0][]]& as a string and [] appended to it. Just replace Print with CellPrint or copy the output as InputText and you'll see what I mean. – swish May 13 '17 at 00:03

Examine Print[ToString[#0][]] &[] // Trace. Convert the output to input to help distinguish strings from symbols. – Michael E2 May 13 '17 at 01:01
