#55553 — Running python scripts from the command line.

I've recently started to program. Python is my first language, so I'm
a complete beginner. I've been trying to call python scripts from the
command line by entering this command into it:

>>>python test.py

But it gives me this error message:

>>>python test.py
  File "<stdin>", line 1
    python test.py
                   ^
SyntaxError: invalid syntax

I know that test.py exists, and the script is correct (here is is
anyways):

a = 1
if a:
    print 'Value of a is', a

I am using python 2.7.1 installed on Windows 7. This seems like
something that should be easy, so I'm sure I'm just missing a very
small problem. Any help is greatly appreciated.

Thanks,
Anderson

You're already in Python when you type that. If you want to run a
script, you need to call Python from your normal shell, not from
inside the Python interpreter.

$ python
Python 2.6.6 (r266:84292, Jan 10 2011, 20:14:15)
[GCC 4.2.1 (Apple Inc. build 5659)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> exit()
$  python test.py
Value of a is 1

Wow, thank you very much for your help. This worked absolutely great.
I feel like a huge n00b after that though; it was just so obvious!
Anyways, like I said before, thank you very much for your help.
