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

问题

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

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:

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

回答1:

You assigned to a local name len:

len=len(word)

Now len is an integer and shadows the built-in function. You want to use a different name there instead:

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

Other tips:

• Use not instead of testing for equality to False:

  while not n:
  

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

  while y:
