How can i solve this problem with classes in VSCode? [duplicate]

This is the error, I have no idea where the fault is:
> & C:/Users/tanel/AppData/Local/Programs/Python/Python38/python.exe
"c:/Users/tanel/Documents/Projects/Coding/Python/Game Alien/game.py"
File "<stdin>", line 1
& C:/Users/tanel/AppData/Local/Programs/Python/Python38/python.exe "c:/Users/tanel/Documents/Projects/Coding/Python/Game Alien/game.py"
^
SyntaxError: invalid syntax

You're getting a Python SyntaxError because you are trying to run a PowerShell command in the Python shell:
>>> & C:/Users/tanel/AppData/Local/Programs/Python/Python38/python.exe "c:/Users/tanel/Documents/Projects/Coding/Python/Game Alien/game.py"
exit out of that shell and then run your PowerShell command in PowerShell. The prompt should look something like
PS C:\>
The Python shell is for running code interactively, e.g. you could type something like import pygame or print("Hello, world!") directly into it.

To solve this error, just write this command in your terminal :
>>> exit()

Why This Program is not Running [duplicate]

I'm trying to learn Python and am trying to execute a python file in terminal. I'm using 2.7.3 python version on my OS X. I've changed the directory in terminal to where the file is located, but I'm getting an error in terminal:
>>> python ex1.py
File "<stdin>", line 1
python ex1.py
^
SyntaxError: invalid syntax
The ex1.py file contains:
print "Hello World!"
print "Hello Again"
print "I like typing this."
print "This is fun."
print 'Yay! Printing.'
print "I'd much rather you 'not'."
print 'I "said" do not touch this.'
Any ideas on how to fix this? Thx a bunch.

>>> python ex1.py
You are trying to run your script from within a python interpreter. You don't want to do that.
Instead, just run that command in a terminal, not in the interpreter
$ python ex1.py
If you are still in the interpreter, you can press ctrl+d to leave it and return to the 'normal' terminal

Exit python interpreter by typing exit() or press Crtl+Z
You will see the terminal now.
Type python file_name.py to run the code.
Happy coding!!!

Try type
exit()
return; then
python ex1.py
return

I have just started python and stuck in this error. While typing python helloworld.py this error is occurring My helloworld.py file is openning in windows cmd but it's not opening in python.exe

install error or error running python file

I am running a basic Python file on Windows XP from IDLE.
The file name is assignment1.py.
The file content is:
import sys
var = 5
but when I run it, it gives the error:
Command: python assignment1.py
SyntaxError: invalid syntax
Then I tried another thing which also gave an error:
Command: which python
SyntaxError: invalid syntax
Not sure if the installation is wrong or something.
I am able to run the print command successfully:
>>> print "I am working fine"
I am working fine
Not sure of the issue. Request help.

It looks like what you are entering as the "command" is being interpreted as Python code. I mean, python assignment1.py is interpreted as Python code. The result is as expected:
$ python -c 'python assignment1.py'
File "<string>", line 1
python assignment1.py
^
SyntaxError: invalid syntax
You need to run the file in the correct way, probably via the IDLE menu or by pressing F5. You can check these questions for details:

A error about pyuic4

I'm trying to transform my ui file to .py file, but when I run pyuic4 in the shell, I get an error:
# pyuic4 main.ui > main_ui.py
File "/usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py", line 2
exec /usr/bin/python /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py ${1+"$#"}
^
SyntaxError: invalid syntax
my os is fedora16

On Linux, pyuic4 should be a bash script that would usually be installed as /usr/bin/pyuic4.
The error
exec /usr/bin/python /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py ${1+"$#"}
^
SyntaxError: invalid syntax
would be produced if you attempted to run that bash script with python.
However, the error message also gives the source file location as
File "/usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py", line 2
which doesn't make much sense, because that should be a python script.
Has /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py somehow been over-written with the bash script?
Try opening that file, and also /usr/bin/pyuic4, in an editor to see what they contain.

If you want use python2, just type
python2-pyuic4 main.ui > main_ui.py
