Python - How do you run a .py file?

I've looked all around Google and its archives. There are several good articles, but none seem to help me out. So I thought I'd come here for a more specific answer.

The Objective: I want to run this code on a website to get all the picture files at once. It'll save a lot of pointing and clicking.

I've got Python 2.3.5 on a Windows 7 x64 machine. It's installed in C:\Python23.

How do I get this script to "go", so to speak?

=====================================

Seeing as how this is top result on Google, here's a useful link I found over the years:

http://learnpythonthehardway.org/book/ex1.html

For setup, see exercise 0.

=====================================

As requested, here's the code I'm using:

"""
dumpimages.py
Downloads all the images on the supplied URL, and saves them to the
specified output file ("/test/" by default)

Usage:
    python dumpimages.py http://example.com/ [output]
"""

from BeautifulSoup import BeautifulSoup as bs
import urlparse
from urllib2 import urlopen
from urllib import urlretrieve
import os
import sys

def main(url, out_folder="C:\asdf\"):
    """Downloads all the images at 'url' to /test/"""
    soup = bs(urlopen(url))
    parsed = list(urlparse.urlparse(url))

    for image in soup.findAll("img"):
        print "Image: %(src)s" % image
        filename = image["src"].split("/")[-1]
        parsed[2] = image["src"]
        outpath = os.path.join(out_folder, filename)
        if image["src"].lower().startswith("http"):
            urlretrieve(image["src"], outpath)
        else:
            urlretrieve(urlparse.urlunparse(parsed), outpath)

def _usage():
    print "usage: python dumpimages.py http://example.com [outpath]"

if __name__ == "__main__":
    url = sys.argv[-1]
    out_folder = "/test/"
    if not url.lower().startswith("http"):
        out_folder = sys.argv[-1]
        url = sys.argv[-2]
        if not url.lower().startswith("http"):
            _usage()
            sys.exit(-1)
    main(url, out_folder)

If you want to run .py files in Windows, Try installing Git bash Then download python(Required Version) from python.org and install in the main c drive folder

For me, its :

"C:\Python38"

then open Git Bash and go to the respective folder where your .py file is stored :

For me, its :

File Location : "Downloads" File Name : Train.py

So i changed my Current working Directory From "C:/User/(username)/" to "C:/User/(username)/Downloads"

then i will run the below command

" /c/Python38/python Train.py "

and it will run successfully.

But if it give the below error :

from sklearn.model_selection import train_test_split ModuleNotFoundError: No module named 'sklearn'

Then Do not panic :

and use this command :

" /c/Python38/Scripts/pip install sklearn "

and after it has installed sklearn go back and run the previous command :

" /c/Python38/python Train.py "

and it will run successfully.

!!!!HAPPY LEARNING !!!!

Your command should include the url parameter as stated in the script usage comments. The main function has 2 parameters, url and out (which is set to a default value) C:\python23\python "C:\PathToYourScript\SCRIPT.py" http://yoururl.com "C:\OptionalOutput\"

Usually you can double click the .py file in Windows explorer to run it. If this doesn't work, you can create a batch file in the same directory with the following contents:

C:\python23\python YOURSCRIPTNAME.py

Then double click that batch file. Or, you can simply run that line in the command prompt while your working directory is the location of your script.

use IDLE Editor {You may already have it} it has interactive shell for python and it will show you execution and result.

On windows platform, you have 2 choices:

  1. In a command line terminal, type

    c:\python23\python xxxx.py

  2. Open the python editor IDLE from the menu, and open xxxx.py, then press F5 to run it.

For your posted code, the error is at this line:

def main(url, out_folder="C:\asdf\"):

It should be:

def main(url, out_folder="C:\\asdf\\"):

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.
