I am a beginner to python and am at the moment having trouble using the command line. I have a script test.py (which only contains print("Hello.")), and it is located in the map C:\Python27. In my system variables, I have specified python to be C:\Python27 (I have other versions of Python installed on my computer as well).
I thought this should be enough to run python test.py in the command line, but when I do so I get this:
File "<stdin>", line 1 python test.py ^ SyntaxError: invalid syntax What is wrong? Thanks in advance!

You can clear up this invalid syntax in Python by switching out the semicolon for a colon. Here, once again, the error message is very helpful in telling you exactly what is wrong with the line.
The “Python is not recognized as an internal or external command” error is encountered in the command prompt of Windows. The error is caused when Python's executable file is not found in an environment variable as a result of the Python command in the Windows command prompt.
Syntax errors are produced by Python when it is translating the source code into byte code. They usually indicate that there is something wrong with the syntax of the program. Example: Omitting the colon at the end of a def statement yields the somewhat redundant message SyntaxError: invalid syntax.
Syntax errors are mistakes in the use of the Python language, and are analogous to spelling or grammar mistakes in a language like English: for example, the sentence Would you some tea? does not make sense – it is missing a verb. Common Python syntax errors include: leaving out a keyword.
Looks like your problem is that you are trying to run python test.py from within the Python interpreter, which is why you're seeing that traceback.
Make sure you're out of the interpreter, then run the python test.py command from bash or command prompt or whatever.

Don't type python test.py from inside the Python interpreter. Type it at the command prompt, like so:
