【问题描述】：

我的问题是： 编写一个 python 程序，获取长度超过三个字母且以相同字母开头和结尾的单词的分数（这可以是随机字典中的名称列表）？

我的输出应该是： "长度超过三个且以相同字母开头和结尾的单词的比例：0.065"

请任何人！帮我解决这个问题，我知道这是一个愚蠢的问题，但我只是从 python 开始。

基于这个程序，我应该解决我的程序。

# Function to determine if a string contains three consecutive double lectures
# It has been switched slightly to use a for loop instead of a while loop.
def three_double(s):
    for i in range(0, len(s)-5):
        if s[i] == s[i+1] and s[i+2] == s[i+3] and s[i+4] == s[i+5]:
            return True
    return False

# Function to apply the three_double test to each string in the words
# list.  It counts the number of results.
def find_three_double(words_list):
    count = 0
    for w in words_list:
        if three_double(w):
            print w
            count = count + 1
    if count == 0:
        print '<None found>'
    else:
        print count, 'found'

#  The if statement here tests to see if this is being run as a
#  program or being imported as a module.  When the value of __name__
#  is "__main__" Python is running this is the "main program".  If
#  this file had been imported as a module then the value of __name__
#  would have been "three_double" and the block of code following the
#  if would not be executed.  This establishes one of the central
#  differences between programs and modules and shows how the same
#  code may be used as a program or as a module.

if __name__ == "__main__":
    # Access the file containing the valid words
    words_file = open('words.txt')

    # Read each word, remove the white space and the \n and append it to the list
    words_list = []
    for w in words_file:
        w = w.strip().strip('\n')
        words_list.append(w)

    # Find the three doubles
    find_three_double(words_list)

【问题讨论】：

哪一部分给你带来了问题，你已经尝试过什么？

是实验室的一部分。十步之差。

给我带来麻烦的部分是如何获得找到的单词的分数。您是否知道任何解释或有与此相关的示例的网站？谢谢。

【参考方案1】：

由于这是家庭作业，因此为您编写代码不是一个好主意。因此，理想情况下，您需要做的是获取符合标准（您提到的）的单词并将它们存储在列表中。然后取列表的长度。

之后，您可以将找到的单词列表的长度除以字典中的作品数。
