程序不寫列表按字母順序排列的輸出到文件

這裏是我的代碼：程序不寫列表按字母順序排列的輸出到文件

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()

下面是輸出：

Best Picture

以上輸出不正確的輸出我在尋找。顯然，它不是按字母順序輸出到輸出文件，我不知道如何解決它。

預期的輸出應沿着這些路線：

Best Picture 
Best Picture 
Best Picture 
Biggest Gross 
Biggest Gross

Sundance

對於上述輸出唯一的一點是，他們將在文件中這些話更多的實例，但它只是一個例子。

「MoviesTotalEarnings.txt」如何顯示？我問，因爲'allItems.sort（）'是排序列表的列表。不是字符串列表。 – Marcin 2014-12-04 05:06:44

我做了答案。想想，你需要指定一個將用於排序的鍵。 – Marcin 2014-12-04 05:16:03

我認爲你需要添加關鍵是你的排序。因此，要對第三列進行排序，您需要

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

這工作完美。謝謝。 – TZK203 2014-12-04 05:19:00
