选择的猜字游戏单词

Question

我正在尝试让用户选择他们想要的单词长度，但我遇到了一些困难，不知道哪里出了问题。我刚学了三个月的Python，还是个新手，虽然我查过很多关于Python的资料，但对所有内置函数都不太了解，或者说我知道但不知道怎么用。

这是我的代码：

from random import *
import os


wordlist_1 = 'cat dog'.split()                #Is all the wordlist be in a function to all three of wordlist?
wordlist_2 = 'donkey monkey dragon'.split()   #Like def wordlist():
wordlist_3 = 'dinosaur alligator buffalo'.split()

keep_playing = True
def print_game_rules(max_incorrect,word_len):
    print"You have only 7 chances to guess the right answer"
    return

def length_1():
    print('You will have length of 3 word')
    return
def length_2():
    print('You will have length of 6 word')
    return
def length_3():
    print('You will have length of 8 word')
    return

def Welcomenote():

    print('Select One Category')
    print(' 1: length of 3 word')
    print(' 2: length of 6 word')
    print(' 3: length of 8 word') 

    choice = {
        "1": length_1,
        "2": length_2,
        "3": length_3 }

    choose = input()
    return

def getrandomword():
    wordindex = random.randint(0,len(wordlist)-1)
    return wordlist[wordindex]

def get_letter():
    print
    letter = raw_input("Guess a letter in the mystery word:") 
    letter = letter.strip()
    letter = letter.lower()
    print
    os.system('cls')
    return letter

现在错误提示是：

追踪记录（最近的调用在最前面）：
文件 "P:\Lesson 8\Hangman 2 - Copy.py"，第156行，
secretword = getrandomword(word)

类型错误：getrandomword() 不接受任何参数（给了1个）

Answer 1

关于randint不存在的错误，你需要从random模块中导入函数名。

from random import *

所以你可以直接调用这个函数。

wordindex = randint(0,len(wordlist)-1)

为了避免导入太多不必要的东西，我建议你要么导入整个模块（这样就不用修改函数调用），要么直接导入你需要的函数名（这样就不会把其他不需要的随机函数弄到全局命名空间里）。

import random
# or
from random import randint

不过你代码里还有其他一些问题。

变量length_1、length_2和length_3最开始被赋值为字符串。后来你又把它们重新定义成函数。在这些函数里，你返回的是这些函数的名字（而不是那些字符串）。在Welcomenote()里，你返回的也是这些函数（而不是字符串），所以这就错了两次。你应该使用不同的名字。

另外，看起来你是想把它们定义成一个单词列表。如果保持现在的样子，你得到的将是单个字母，而不是一个列表。你应该把它们定义成一个列表。

wordlist_1 = ['cat', 'dog']
# or alternatively
wordlist_1 = 'cat dog'.split() # splits the string up to a list of words separated by whitespace

可能还有其他问题，但这些是最明显的，需要修正的地方。
