error running script in python3.7.2 interpreter
#1
hi there ,
I am trying to run one of my script file i.e firstfile.py on my windows 2008 r2 machine
where in I have installed python3.7.2.
While installing I selected "Add to Path" option .
my installation path is default i.e C:\Users\Administrator\AppData\Local\Programs\Python\Python37
I have saved my firstfile.py python script file in the same location.
When trying to run this file from shell i.e interpreter following error is coming:
Error:
Python 3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 23:09:28) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> python.exe C:\Users\Administrator\AppData\Local\Programs\Python\Python37\myf irstfile.py File "<stdin>", line 1 python.exe C:\Users\Administrator\AppData\Local\Programs\Python\Python37\myf irstfile.py ^ SyntaxError: invalid syntax
how to run this file....and tried to save the above python.exe path in system PATH variable also...but still can not run file..
Running the same file from cmd(windows console) it is running fine...no issues there...

Thanx in advance

you are trying to run it from python interactive mode (>>> shows you are in interactive mode)
this should be executed from command prompt (shell)

As mention you can not do it like this in interactive mode.
A couple of advice C:\Users\Administrator\AppData\Local\Programs\Python\Python37,i don't like this default path and you should not save your python file there.
I give advise here to make your own path shorter Path.

Can use any folder as python should be in Windows Path.
A little long to type just to run myfirstfile.py
python.exe C:\Users\Administrator\AppData\Local\Programs\Python\Python37\myfirstfile.py
Example of running file from own made folder.
# myfirstfile.py
s = 'Hello World'
print(s)
Running from cmd or better cmder(then can also jump straight to any folder from file explorer).
E:\div_code
λ python myfirstfile.py
Hello World
Can start code this in interactive mode with python -i myfirstfile.py.
E:\div_code
λ ptpython -i myfirstfile.py
Hello World

# Now can test more on code in interactive mode
>>> s.upper()
'HELLO WORLD'

>>> s.count('l')
3
The combination of ptpython(what i use) or IPython,with cmder make this whole lot better on Windows.

that means you can not run any *.py i.e script file from python interactive shell(interpreter)which is there when I install IDLE..I just wanted that clarity....

You run a file in shell bye using exec() or subprocess.
Not so common to do this,as in most cases this is not needed.
E:\div_code
λ ptpython
>>> exec(open('myfirstfile.py').read())
Hello World

>>> import subprocess

>>> subprocess.run(['python', 'myfirstfile.py'])
Hello World
