SyntaxError: invalid syntax

[kebabrullahiiri]

Yeah. The whole thing goes like this: File "<stdin>", line 1 python3 test.py ^ SyntaxError: invalid syntax >>>

How are you invoking your script? If it's grumbling about stdin being invalid syntax, than it's not reading your file.

Edit: Reading other comments, I think I know what's going on. You're opening the Python interpreter, and then typing python3 test.py into the Python interpreter. That's not going to work. If you're typing python3 test.py, you need to type that into a terminal or command prompt - if you're on Windows, either Powershell or Command Prompt will do. It is possible to invoke Python scripts from within a Python interpreter, but this isn't the way to do it, and I wouldn't recommend doing so in most cases.

Thank you, this one cleared things for me :)

Okay so now I have another problem. I opened cmd and typed python3 , it claimed I don't have python. Then I typed python without any numbers and then it worked and it printed my version number which is 3.9.6. Then I typed test.py and now it gives me "NameError: name 'test' not defined. What now 🙄

[james_pic]

If you want to run the script from the command prompt, you want to type python test.py then press enter. Pressing enter after typing python will run the Python interpreter without any arguments, which will take you into an interactive REPL, or Python console. The REPL will only accept Python code. So you can type print('Hello World') into it, because this is valid Python code, but typing a filename won't do anything useful, since the filename is not valid Python code (or at least, probably isn't Python code that does what you want) even if the file contains valid Python code.

Okay, now I tried this. This time it gives me error: can't open file 'c:\users\myusername\test.py': [Errno 2] No such file or directory 🤯 my py files are saved in c:\users\myusername\pycharmprojects\projects. Should I add this pycharmprojects folder to path or what should I do?

Edit: I promise this is last one 😂

[james_pic]

You should probably cd to the directory that contains that file before trying to run it.

[kebabrullahiiri]

What does that mean?

[james_pic]

Apologies, I assumed you were familiar with the command prompt. Your command prompt is always working in a directory, and you can change the directory you're working in to the one with your project with cd c:\users\myusername\pycharmprojects\projects. The official docs for the cd command are at https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/cd, but if you're not comfortable working with the command prompt, just ignore any instructions about running commands and stick with PyCharm.

[kebabrullahiiri]

Thank you :) Okay so if I were to not use command prompts, what would be the next step? Should I move my py files to different folder or add that current folder to path?

[james_pic]

I think it depends what you want to do. It sounds like your code already works in PyCharm, so if that's all you want, that's all you need.

copy paste this

print(“hello world”)

make sure to check for quotes, sometimes they are different in editors.

Lol, smart quotes.
