Question

这是我的代码：

def typeMovie():
    import os
    os.chdir("/Users/Name/Desktop/Data Sets")

    input_file = open("MoviesTotalEarnings.txt", "r")
    output_file = open("MoviesTotalEarningsType.txt", "w")

    allItems = []

    for line in input_file:
        data = line.split("\t")

        allItems.append(data)

    allItems.sort()

    for data in allItems:
        output_file.write("{}\n".format(data[2]))

    input_file.close()
    output_file.close()

typeMovie()

这是输出：

以上输出不是我正在寻找的正确输出。显然，它不是按字母顺序写入输出文件，我不知道如何解决它。

预期的输出应该是这些：

Best Picture
Best Picture
Best Picture
Biggest Gross
Biggest Gross
Series
Series

Sundance

上述输出的唯一内容是它们会在文件中包含更多这些单词的实例，但它只是一个例子。

Answer 1

我认为您需要为您的排序添加密钥。因此，要排序第三列，您需要

 allItems.sort(key=lambda v: v[2])

Answer 2

allItems.sort(key=operator.itemgetter(2))

程序不按字母顺序将列表输出写入文件
