Additionally, I do have PyCharm installed (As you can tell, I am a beginner), is PyCharm the same thing as Python? Thank you in advance! No, PyCharm is an editor and Python IDE; it is not the same as Python. Python is a programming language. The problems you have been having could be caused by PyCharm not being set up to work with your installation of Python. To see if Python has been installed correctly, open a Windows console. If you don't know how, one way is to hit the Windows key and type "cmd". Windows will offer "Command Prompt". Hit the ENTER key to accept it, and a console window will open. (There are more convenient ways, but we don't need to get into them right now). In the console window, type (without the quotes) "py -V". You should see something like this (The first line is what I typed, the second line is the response): C:\Users\tom>py -V Python 3.10.9 If this works, Python has been installed and apparently working. If it is working, save the Python program from your lesson as a file with a name such as such as "lesson1.py". In an open console window. try to run it by typing py lesson1.py Instead of just "lesson1.py", you will either need to change directory (using the cd command) to the directory that contains that file, or you will need to use the full path to the file. For example, if the file is c:\temp\python\lesson1.py then run it by typing py c:\temp\python\lesson1.py Let us know how it goes. -- https://mail.python.org/mailman/listinfo/python-list

This list strips attachments such as images, so I don't know which book you're referring to. I'd go for Python 3.11 and the installer "Windows installer (64-bit)" at https://www.python.org/downloads/release/python-3112/, i.e. "https://www.python.org/ftp/python/3.11.2/python-3.11.2-amd64.exe; (assuming that it's a 64-bit PC). To run Python, the recommended way is to use the Python Launcher, py.exe (so type "py my_program.py" in a Command window), or just double-click on it if it's a GUI program. As for PRN, that's the printer. Does anyone use PRN these days? And, no, PyCharm is not the same thing as Python. PyCharm is an IDE (integrated development environment) for Python, but Python is its own thing. -- https://mail.python.org/mailman/listinfo/python-list

If you installed the conventional way, use the command name "py" instead of "python" to run things from a command shell. Alternatively, you could try an installation of Python from the Microsoft Store (as the little stub program named python, which Microsoft preinstalls for the express purpose of giving you this hint). There are times when getting Python working without hassle is easier when going that route. You *can* add python to the search PATH, there's an option in the installer (you can rerun this from the Apps & features Settings applet)... in the screen for advanced options there's something that says "Add python to environment variables" or similar wording. >I have been at this for 4 days now at least three hours each day...Any information or help you can provide would be greatly appreciated. Additionally, I do have PyCharm installed (As you can tell, I am a beginner), is PyCharm the same thing as Python? No. It's an "integrated development environment" - editor, debugger, source control wrangler and many other things. It still needs to have a working Python installed. It will probably find the installed Python more easily than you will. The concept of an IDE is you can do all your programming work without leaving it - you don't have to hop between editor, command line, and invoke other tools. PyCharm is only one of many entrants in this space for Python programmers. It's excellent, but I find it rather, ummm, "bulky", for beginners - there are a ton of features you'll not use early on in your journey, and thus I find it makes it much harder to find the things you do need in menus, help, etc. Up to you whether you push ahead with using it now, or leave it for a bit later when you're doing more complex things. We have no idea what book you're using, by the way, as the list strips images and other attachments. In any case, there are hundreds of Python books out now, most of us don't know about a particular one (unless we wrote it :) ) -- https://mail.python.org/mailman/listinfo/python-list
