Python TypeError: 'int' 对象不可调用,,, len()

TypeError: 'int' object is not callable,,, len()

提问by Gilad Wharton Kleinman

I wrote a program to play hangman---it's not finished but it gives me an error for some reason...

我写了一个程序来玩刽子手——它还没有完成，但由于某种原因它给了我一个错误......

import turtle
n=False
y=True
list=()
print ("welcome to the hangman! you word is?")
word=raw_input()
len=len(word)
for x in range(70):
    print
print "_ "*len
while n==False:
    while y==True:
        print "insert a letter:"
        p=raw_input()
        leenghthp=len(p)
        if leengthp!=1:
            print "you didnt give me a letter!!!"
        else:
            y=False
    for x in range(len):
        #if wo
        print "done"

error:

错误：

    leenghthp=len(p)
TypeError: 'int' object is not callable

You assigned to a local name len:

您分配了一个本地名称len：

len=len(word)

Now lenis an integer and shadows the built-in function. You want to use a differentname there instead:

Nowlen是一个整数并隐藏内置函数。您想在那里使用不同的名称：

length = len(word)
# other code
print "_ " * length

Other tips:

其他提示：

• Use notinstead of testing for equality to False:

  while not n:
  

• Ditto for testing for == True; that is what whilealready does:

  while y:
  

• 使用not而不是测试是否相等于False：

  while not n:
  

• 同上用于测试== True；这就是while已经做到的：

  while y:
