Question

我已经计算了具有多个记录的列（String）中的单词和字符的数量，并存储在两个不同的列中。我想按降序排序单词数量（标记）。例如：

CITY OF AMSTERDAM，3,17

token_map = {}
words = []

with open('test.csv', 'r') as fopen:
    lines = fopen.readlines()
    for line in lines:
        line = str.strip(line)
        words_in_line = str.split(line, " ")
        token_map[line] = "" + str(len(words_in_line)) +","+ str(len(line))
        words.append(words_in_line)


print words
print token_map

Answer 1

运行示例会产生很大的不同。我编写了一些数据，然后将toString()函数应用到sorted并按升序获取其项目。如果您需要，可以添加dict。

reverse=True

您选择存储数据的方式似乎很奇怪。如果您使用计数作为第一项的token_map = {} words = [] lines = ['I am the very model\n', 'of the modern\n', 'major general\n'] for line in lines: line = str.strip(line) words_in_line = str.split(line, " ") token_map[line] = "" + str(len(words_in_line)) +","+ str(len(line)) words.append(words_in_line) print words print token_map for item in sorted(token_map.iteritems(), key=lambda item: int(item[1].split(',')[0])): print item，则排序更直接。
