2013年11月5日 · I have written a simple python program using IDLE to run it from command line. I don't have permission to save .py file in python directory (C:\program files\python33) so I saved it to C:\Pyscripts. Also python was already been added to the PATH and I can run a simple print ("Hello") in command line. I have saved this line into a py file and ...

2020年7月13日 · You don't need to read the cmd file line by line. you can simply try the following: import os os.system('myfile.cmd') or using the subprocess module: import subprocess p = subprocess.Popen(['myfile.cmd'], shell = True, close_fds = True) stdout, stderr = proc.communicate() Example: myfile.cmd: @ECHO OFF ECHO Grettings From Python! …

I want to run a python file in my command prompt but it does nothing. These are the screen shots of my program i am testing with and the output the command prompt gives me.

2023年11月6日 · I'm trying to use variables and settings from that file, not to invoke a separate process. Well, simply importing the file with import filename (minus .py, needs to be in the same directory or on your PYTHONPATH) will run the file, making its variables, functions, classes, etc. available in the filename.variable namespace.

then import your file so import example_file. then run the command with example_file.hello() This avoids the weird .pyc copy function that crops up every time you run python -c etc. Maybe not as convenient as a single-command, but a good quick fix to text a file from the command line, and allows you to use python to call and execute your file.

Note on Python version: If you are still using Python 2, subprocess.call works in a similar way. ProTip: shlex.split can help you to parse the command for run, call, and other subprocess functions in case you don't want (or you can't!) provide them in form of lists: import shlex import subprocess subprocess.run(shlex.split('ls -l'))

2011年1月7日 · The PATH environment variable lists all the locations that Windows (and cmd.exe) will check when given the name of a command, e.g. "python" (it also uses the PATHEXT variable for a list of executable file extensions to try). The first executable file it finds on the PATH with that name is the one it starts.

#!/usr/bin/python Muddling through. You can see what python you're currently using by using the unix which command, so if you want to see where your python is coming from, use this command: which python or on Windows (cygwin probably can run the shebang): where python On Linux/Unix, you'll need execution perms to run the file as well, in that ...

2012年2月29日 · Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

2016年10月12日 · Anaconda should add itself to the PATH variable so you can start any .py file with "python yourpythonfile.py" and it should work from any folder. Alternatively download pycharm community edition, open your python file there and run it. Make sure to have python.exe added as interpreter in the settings.
