Python for items list, to indivdual string?

Question

Just wondering if someone can be kind enough to tell me what I am doing wrong. working on a bit of code, with use with my cherrypy project

import glob
import os

def get_html(apath):
    print (apath)
    fhtml = open(apath,'r')
    data = fhtml.read()

    return data


article_path  = os.getcwd() +'/articles/*.html'
myArticles = [glob.glob(article_path)]

print len(myArticles)

for items in myArticles:
    get_html(items)

Results in:

['/home/sd/Documents/projects/cherryweb/articles/Module 5-Exploitation Techniques And Exercise.pdf.html']
Traceback (most recent call last):
  File "fntest.py", line 22, in <module>
    get_html(items)
  File "fntest.py", line 10, in get_html
    fhtml = open(apath,'r')
TypeError: coercing to Unicode: need string or buffer, list found

I assume its because the filename I'm passing has the [' and '] from list on the string, I could write a function to trim these parts off, but it that the only option, or am I doing something stupid.

Thanks

myArticles = [glob.glob(article_path)]

should be:

myArticles = glob.glob(article_path)

glob.glob returns a list, by adding [] around it you made it a list of list.

So, in this loop:

for items in myArticles:
    get_html(items)

you actually passed the whole list to get_html and open raised that error.

Demo:

>>> open([])
Traceback (most recent call last):
  File "<ipython-input-242-013dc85bc958>", line 1, in <module>
    open([])
TypeError: coercing to Unicode: need string or buffer, list found
