Top Forums Programming Populating Lists in Def using Python Post 302869899 by metallica1973 on Thursday 31st of October 2013 11:49:56 AM

ok I got my function to work using:

Code:
def list_files():
    content = []
    for files in os.walk('var/www/html/data/customer/log'):
       content.extend(files)
    return content

next stupid question is how do I access one of the many files in the function? So the results of os.walk populates my list -- content [] with the files in the directory:

Code:
list_files()
print list_files()
['var/www/html/data/customer/log', [], ['file1', 'file2', 'file3', 'file4']]

so how would I access that information so I can add additional logic to my script? when I attempt to access anything in my list, I get the following error

Code:
content[3]

NameError: name 'content' is not defined

when not using a function I can access the elements a such:

Code:
In [66]: func = []

In [67]: func.extend( ("blah1","blah2" ) )

In [68]: print func
['blah1', 'blah2']
In [69]: print func[0]
blah1

In [70]: print func[1]
blah2
