刽子手一词被选中

Question

我试图让用户选择他们想要的单词的长度,但我很难弄清楚出了什么问题.我是Python的菜鸟,我学了3个月,我搜索过Python.我不知道所有Python内置函数或我可能知道但不知道如何使用它们.

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

TypeError:getrandomword()不带参数(给定1个)

Answer 1

要解决有关randint不存在的错误,您已在random模块中导入了函数名称.

from random import *

所以直接调用该函数.

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

所以你输入的数量不是你所需要的,我建议你直接导入模块(所以你不需要更改函数调用)或单个名称(所以你不会用另一个来污染全局命名空间)您不使用的随机函数).

import random
# or
from random import randint

但是,您的代码中还存在其他一些问题.

变量length_1,length_2并length_3分配字符串.之后,您将它们重新定义为函数.在这些函数中,您将返回那些函数名称(而不是那些字符串).稍后Welcomenote(),您将返回这些函数(而不是那些字符串),因此它是错误的.你应该使用不同的名字.

此外,看起来你的意思是他们是你的单词列表.如果保持原样,您将获得单独的字母.它应该是一个列表.你应该定义它们.

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

可能还有其他的,但这些是突出的,应该修复的大的.
