Subprocess Connection Error
I bought a book called Coding for Beginners to learn how to code using Python. The first few exercises went fine. When I got to the page called Recognizing types and did the exercise and saved it and tried to run the module it comes up with a Subprocess Connection Error. It says, "IDLE's subprocess didn't make connection. See the Start up failure section of the IDLE doc, online at https://docs.python.org/3/library/idle.html#startup-failure." I went there and it said to try uninstalling python and then reinstalling it. I did this and it did the same thing again. It also said something about it is because of the antivirus software. I tried installing python on a different computer and it happened at the exact same place in the exercises in the book. I am far from being a computer whiz, just thought it would be fun to learn some simple coding. Any help would be appreciated. One more thing, the book says to save it as "types.py".
