Python - How do you run a .py file?

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.

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\\"):
