如何按长度对单词列表进行排序 [英] How to sort a list of words by length

问题描述

我想根据长度对列表中的单词进行排序.

I want to sort words in a list based on length.

测试用例为{'cat','jump','blue','balloon'}

通过此方法运行时，它将打印出以下内容:

When run through this method it will print something along the lines of:

{'balloon','jump','blue','balloon'}

我遇到的另一个问题是，我们使用的python类型工作正常，但是当我尝试在Python 3.5.2 shell中运行.py时，就会出现错误.

Another problem I have run into, is that the type of python we were using worked fine, however when I try to run the .py in the Python 3.5.2 shell, it comes up with errors.

我主要只需要知道我做错了什么，以及我可以做些什么来对其进行修复以使其起作用.感谢您的帮助！

I mainly just need to know what I did wrong, and what I can do to fix it so that it works. Any help is appreciated!

.py文件可在此处找到:

def wordSort():
    words = []
    minimum = 'NaN'
    index = 0
    x = 0    
    y = 0    
    z = 1
    #How many words to be entered
    length = input('How many words would you like to enter? ')
    #Put words in the number of times you entered previously    
    while not z >= length + 1:
        words.append(raw_input('Enter word #' + str(z) + ': '))
        z += 1
    while x < length:
        minimum = words[x]
        #Goes through the list and finds a smaller word
        while y < length:
            if len(words[y]) < len(minimum):
                minimum = words[y]
                index = y
            y += 1
        words[index] = words[x]
        words[x] = minimum
        x += 1
    print words
