They don't but you do need to pass a valid path to open()
Thus if your code is running from folder X and the files
are in folder Y you need to tell open to open Y/filename
rather than just filename. Similarly you need to tell glob
to glob(Y/pattern)
The other possibility is to change the working directory to
Y using os.chdir(Y)

So you will need to store that result in a variable and add the
totals:
total = 0
for file in filelist:
result = linesInFile(file)
print file, ": ", result # might not need/want this
total += result
print total

Make the dictionary outside your loop and pass it into the full
analysis program:
# PSEUDO CODE ONLY!
words = {}
total = 0
for file in Flist
words, count = analyzeFile(file, words)
total += count
print total
for word in words:
print word, ':', words[word]
def AnalyzeFile(f, w)
linecount = 0
for line in f:
for word in line.split()
w[word] = w.get(word,0) + 1
return w,linecount

No it sounds like a variable position problem, and possibly
a namespace issue too.
