Question

在python中导致此错误的原因是什么？

Traceback (most recent call last):
  File "F:/coding/python/python programming for absolute beginners/chapter 4/
  The Jumble Game.py", line 9, in <module>
    p=random.randrange(len(word))
AttributeError: 'str' object has no attribute 'randrange'

代码：

import random
print"\t\t\tThe Jumble Game"
print"In this program you will be given a jumble word and you have to guess that word"
set=("book","parrot","rabbit")
word=random.choice(set)
random=""
jumble=""
while(word):
    p=random.randrange(len(word))
    random=random+word[position]
    word=word[:position]+word[(position+1):]
print("The jumble word is",random)

Answer 1

您重复使用了名称random：

random=""

从那时起，名称random引用字符串对象，而不是模块。重命名该变量以不影响您导入的模块。

要改变一个单词，它会更容易使用random.shuffle()：

word = random.choice(set)
letters = list(word)
random.shuffle(letters)
jumbled_word = ''.join(letters)
print "The jumble word is", jumbled_word

Answer 2

如何在python解释器中重现此错误：

>>> import random
>>> type(random)
<type 'module'>
>>> random.randrange(2)
1
>>> random.randrange(2)
0
>>> random = ""
>>> type(random)
<type 'str'>

>>> random.randrange(2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'randrange'

通过将随机模块重新定义为字符串类型，您中毒了该井。然后你在字符串上调用方法randrange。而且它告诉你字符串对象没有它。

Python错误＆＃39; str＆＃39;对象没有属性＆＃39; randrange＆＃39;
