PyCharm not outputting result?

Question

PyCharm

Even the simplest print('Hello world') operation seems to be ignored. As a result, only Process Finshed with exit code 0 is obtained, that is, the code was successfully executed, but there is no result. What to do?

Answer 1

I assume you run the script with the green button at the top? And look next to the button to the left of it, what script is indicated? The one you are running? There's a dropdown list.
It is best to add the construction to the text of the script

if __name__ == "__main__":
   print("Hello python")

and a little green triangle will also appear to the left of this line. Run them, and you definitely can't go wrong.
