Cant print list out of python function

Question

Not that great at python so I might be making a mistake, but my SplitAgain only prints the first line outside of the function. I did try having a forloop but that didnt work either.

print 'List Local Files'
localFile = open('Local.csv','r')

for line in localFile:
    splitLine = line.split(",")
    splitAgain = splitLine[9].replace('"', '')

   # print splitAgain


print 'Collection Files'
CollectionFile = open('Collection.csv', 'r')
for line in CollectionFile:
       sLine = line.split(",")

       newArray = sLine[4] + sLine[5]


       newArray2 = newArray.replace("/XXXX/",'')



print splitAgain

I would want splitAgain to print all the values outside of the foorloop, as i will be running a diff on SplitAgain and newArray2 in the second stage.

But at this stage it only gives me the first line.

I did try iteration of the list, but it gave me each character on a new line.

I tried this

  for i in SplitAgain:
    print i;

As I understand you are trying to get the value for a column in a csv file and print it. Here a modified version of your code.

print 'List Local Files'

VALUES_SEPARATOR = ","

with open('./local.csv','r') as localFile :
    lines = []
    for line in localFile:
        #use line[:-1] to remove the end line "n" symbol.
        splitLine = line[:-1].split(VALUES_SEPARATOR)
        splitAgain = splitLine[2].replace('"', '')

        lines.append(splitAgain)#store the line in a out-of-the-loop variable.

    print(lines)

As you can see a list is used to store the result outside of the loop as @tdelaney suggested it in comments. Applyied on this file :

name, owner,"local file names"
foo,bar,"foo the foo"
foofoo,bar,"bar the bar"

It give the following result :

List Local Files
['local file names', 'foo the foo', 'bar the bar']

Is that satisfying your needs ?
I hope so 😉

Maybe you could try making splitAgain as a global variable.

This is how it should be like:

print ('List Local Files')
localFile = open('Local.csv','r')

for line in localFile:
    splitLine = line.split(",")
    splitAgain = splitLine[9].replace('"', '')

   # print (splitAgain)


print ('Collection Files')
CollectionFile = open('Collection.csv', 'r')
for line in CollectionFile:
       sLine = line.split(",")

       newArray = sLine[4] + sLine[5]


       newArray2 = newArray.replace("/XXXX/",'')



print (splitAgain)

This is python so no need for ;.
