Question

在python上没那么好，所以我可能犯了一个错误，但是我的SplitAgain只打印了函数之外的第一行。我确实试过了一个forloop，但那也没有用。

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

我希望splitAgain打印foorloop之外的所有值，因为我将在第二阶段在SplitAgain和newArray2上运行差异。

但在这个阶段它只给了我第一行。

我确实尝试了列表的迭代，但它给了我一个新行的每个字符。

我试过这个

  for i in SplitAgain:
    print i;

据我所知，您正在尝试获取csv文件中列的值并进行打印。这是代码的修改版本。

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)

正如您所看到的，列表用于将结果存储在循环之外，正如@tdelaney在评论中所建议的那样。适用于此文件：

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

它给出了以下结果：

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

这是否满足您的需求？我希望如此;）
