python程序，带有match-tu结尾

Question

# 5.- match_ends
# Given a list of strings, return the count of the number of
# strings where the string length is 2 or more and the first
# and last chars of the string are the same.
# Note: python does not have a ++ operator, but += works.
#       For example, the result of n = n + 1 can be also achieved by n += 1.



def match_ends(words):
  # +++your code here+++
  if len(words)>=2:
    return words[0]and words[-1:]==words[-1:]
    words+=words

你们认为我做错了什么？我该如何改进？在

结果如下：

Answer 1

def match_ends(words):
    word_count=len(words)
    results=[]
    for x in words:
        if len(x)>2 and x[0]==x[len(x)-1]:
            results.append(x)
    return word_count,results

word_list=["hello","wow"]
matched_words=match_ends(word_list)
print matched_words

这应该对你有用：）

如果你想让它更像Python，你可以：
