如何从包含5个字母或更少的单词列表中打印单词Python 2.7？

我对python有点陌生，你可能可以从我下面糟糕的代码中看到这一点。如果你玩这个游戏，你可能会发现它真的很难，所以为了让它更容易，我想让它只给用户列表中5个字母或更少的单词。我目前的代码是：

word_site = "http://www.instructables.com/files/orig/FLU/YE8L/H82UHPR8/FLUYE8LH82UHPR8.txt"
response = urllib2.urlopen(word_site)
txt = response.read()
WORDS = txt.splitlines()
randomword=(random.choice(WORDS))

目前，上面的代码从单词列表中获取任何随机单词，我希望它只获取包含5个或更少字母的单词

以下是我的所有代码，如果对您有帮助的话：

import random
import urllib2
loop=True
while loop==True:
    name=raw_input("Hello there! What might your name be? ")
    yesorno=raw_input("Hello " + name + ", would you like to play a friendly game of Guess the Word? Answer either 'yes' or 'no': ")
    if yesorno == "yes":
        loop=False
        print "Ok then, here we go!"
        print "\n"
        print "You have 3 guesses"
        word_site = "http://www.instructables.com/files/orig/FLU/YE8L/H82UHPR8/FLUYE8LH82UHPR8.txt"
        response = urllib2.urlopen(word_site)
        txt = response.read()
        WORDS = txt.splitlines()
        randomword=(random.choice(WORDS))
        lengthrandomword=len(randomword)
        print "I'm thinking of a word with " + str(lengthrandomword) + " letters"
        print "\n"
        if lengthrandomword==2:

Hello there! What might your name be? Alex
Hello Alex, would you like to play a friendly game of Guess the Word? Answer either 'yes' or 'no': yes
Ok then, here we go!


You have 3 guesses
I'm thinking of a word with 14 letters


_ _ _ _ _ _ _ _ _ _ _ _ _ _




Try and guess the word: SOMEWORD
You guessed wrong...


I'll give you a hint: the word STARTS with the letter o and ENDS with the letter g
I'll give you another chance to guess the word: SOMEOTHERWORD
You guessed wrong...


I'll give you another hint: the second letter of the word is v
I'll give you one last chance to guess the word: SOMEOTHERWORD
You guessed wrong...


You're out of chances... the word was: overregulating
I'm sorry to say this but...
YOU LOST!


Wanna play again? If you do, just type 'Start'. If you don't then type 'Exit': 

如果你也能指出我效率低下的地方，这可能也是无处不在的，那将不胜感激

WORDS = txt.splitlines()
WORDS_5_or_less = list(filter(lambda x: len(x) <= 5, WORDS))

---

然后只需从单词中选择“5”或“更少”而不是单词，使用列表理解

short_words = [word for word in txt.splitlines() if len(word) <= 5]

---

您需要使用一些数据结构，比如说字典和一些循环。这不是任何语言的编程方式，至少在python或ruby等语言中是如此。

此外，您可以摆脱重复的ifs块：

只需收到最后一封信：

    lastletter = randomword[-1]

    if not lastletter.isalpha():
        lastletter="I CODED SOMETHING WRONG!"

这同样适用于其他重复块：

    if lengthrandomword==2:
        print "_ _"
        print "\n"
    elif  lengthrandomword==3:
        print "_ _ _"
        print "\n"
    ...
    elif  lengthrandomword==15:
        print "_ _ _ _ _ _ _ _ _ _ _ _ _ _ _"
        print "\n"
    else:
        print "I thought of a word and it's reeeaaaaaly long, you would never guess it, so I'm just gonna tell you that my word was " + randomword

您可以将其缩短为：

    if lengthrandomword in range(2,16):
        print(' '.join('_' * lengthrandomword))
        print('\n')
    else:
        print("I thought of a word and it's reeeaaaaaly long, you would never guess it, so I'm just gonna tell you that my word was " + randomword)

---

你在这里问了两个问题；请不要那样做。如何选择五个字符或更少的单词是一个很好的堆栈溢出问题。这是我的整个计划-我应该如何改进它？属于on。你可以删掉一个好的30 if语句。如果lengthrandomword==x，则替换。。。使用print*lengthrandomwordal，您可以只说lastletter=randomword[-1:]

    if lengthrandomword in range(2,16):
        print(' '.join('_' * lengthrandomword))
        print('\n')
    else:
        print("I thought of a word and it's reeeaaaaaly long, you would never guess it, so I'm just gonna tell you that my word was " + randomword)
