You're not doing anything wrong, but clearly it's not what you want to do. You are running the Python interpreter and not specifying any script to run, so it opens a command prompt and promptly closes it, I'll bet.
What you want to do is open a development environment. Try Idle, it's there in your Python installation. Or download PyScripter, or Jetbrains' PyCharm, or Wing (see recent new version announcement). --- Joseph S. -----Original Message----- From: jjall...@aol.com <jjall...@aol.com> Sent: Thursday, October 8, 2020 12:59 PM To: python-list@python.org Subject: Fwd: Python 3..9.0 Hi, I just downloaded the above for Windows but am unable to get it to run. I have gone to the directory and double-clicked the "python.exe" file but that just brings me to the command prompt. Any suggestions as to what I am doing wrong? Thank you.
