heres the code

Python Syntax (Toggle Plain Text)
  1. #!/usr/bin/python
  2.  
  3. print "Creating a text file with the write() method."
  4. text_file = open("http://www.adamplowman.com/uni_project/log.txt", "w")
  5. text_file.write("Line 1\n")
  6. text_file.write("This is line 2\n")

Re: writing to a file

It's because the builtin function open can only open a file in your filesystem and not an url. If you want to rewrite a file in your website, you should first write a file in your local file system and then use ftp or some other protocol to copy the file to your website.

Re: writing to a file

I'm pretty sure the http protocol doesn't allow write access.

Re: writing to a file

It could work if you pass a file path to open, like uni_project/log.txt , but nothing that starts whith http://.

Re: writing to a file

Did you try something like "../uni_project/log.txt" ? Also you could use os.getcwd() in your program to see the path to the current dir. It would help build a relative path to your file.
