Whenever i run my code on Python IDLE editor,
the output is as follows:

============================== RESTART================================

I am a newbie,it seems i cannot move from this point .
This is my code:
def convert_to_celsius(fahrenheit):
return (fahrenheit - 32) * 5.0 / 9.0
convert_to_celsius(80)

Your code doesn't produce any output (ie: there are no print calls). I don't use Idle myself, but I'm guessing that is why you don't see anything after the restart line. If that is the case, do you see a place in whatever help or documentation you have read that it would be appropriate to mention this? (The distinction is that the REPL window automatically prints the return value of whatever you type in, whereas in a program you get output only if you do the print yourself).

For anyone who reads the doc, the added explanation should help.
