I am trying to pass the value of a nested list into a function (to my "if"
statement) as follows:
textfilelist = [["titlelist1[x][1]"]]
def idfer(listlength, comparelistlength, list):
while x < (listlength - 1):
while y < comparelistlength:
if list == titlelist2[y][1]:
(I cutoff the end to focus on the problem)
#Here i call my function hoping i am passing the value within
textfilelist[0][0] to my function
idfer(textfilelist[0][1], textfilelist[1][1], textfilelist[0][0])
--------------
I don't if there is a "legal" way to do this, but I would appreciate some
guidance.
Thanks,
Brett 4 1491
Do you really want quotation marks around "titlelist1[x][1]" ?
e.g. textfilelist = [["titlelist1[x][1]"]] textfilelist[0][1]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
IndexError: list index out of range

I think so. I later reference it as textfilelist[0][0]. My intent is to be
able to use: titlelist1[x][1] as part of my "if" statement in my function.

Brett,
Hard to tell exactly what you're trying to do here, but it looks like
you'd be better served using one of the built in python data
structures.
For example: If you're trying to compare some elements of these
textfiles that are broken into titles, and contents for each file, try
something like:
myfiles = [ 'test.txt', 'test1.txt', 'test2.txt', 'test3.txt',
'test4.txt' ]
myfiledict = {}
for filename in myfiles:
openfile = file(filename)
myfiledict[filename] = [ line.strip() for line in
openfile.readlines()]
openfile.close()
# easier to read this way
# self.content = []
# for line in f.readlines():
# self.content.append(line.strip())
# then the contents of the file "test.txt" are accessable with the
expression:
# myfiledict['test.txt']
# if you make a few lists of files, then you can compare them like this
for k1, k2 in myfiledict, cmpfiledict:
# if list == titlelist2[y][1]: From your code. The line below is
what
# I think you want.
if k1 == k2:
# Whatever happens in your code that you've clipped.
If you post the rest of your code, or email me, then I'll be happy to
answer your question.

the following in comp.lang.python: I am trying to pass the value of a nested list into a function (to my "if" statement) as follows:
textfilelist = [["titlelist1[x][1]"]]
This list consists of one element -- a character string
"titlelist1[x][1]"
def idfer(listlength, comparelistlength, list):
Don't use "list" as a variable, you are overriding a built-in
function.
while x < (listlength - 1):
Is there any chance you want a for loop rather than a while
loop? "x" does not have a value here, and nowhere do you assign it one.
for x in range(listlength): # range returns 0..arg-1
while y < comparelistlength:
for y in range(comparelistlength):
if list == titlelist2[y][1]:
And where is "titlelist2" defined (I cutoff the end to focus on the problem)
#Here i call my function hoping i am passing the value within textfilelist[0][0] to my function idfer(textfilelist[0][1], textfilelist[1][1], textfilelist[0][0])
There are no elements for [1] (in either position)
