码：

import urllib2 as u
import os as o
inn = 'dword.txt'
w = open(inn)
z = w.readline()
b = w.readline()
c = w.readline()
x = w.readline()
m = w.readline()
def Dict(Let, Mod):
    global str
    inn = 'dword.txt'
    den = 'definitions.txt'
    print 'reading definitions...'
    dell =open(den, 'w')
    print 'getting source code...'
    f = u.urlopen('http://dictionary.reference.com/browse/' + Let)
    a = f.read(800)
    print 'writing source code to file...'
    f = open("dic1.txt", "w")
    f.write(a)
    f.close()
    j = open('defs.txt', 'w')
    print 'finding definition is source code'
    for line in open("dic1.txt"):
        if '<meta name="description" content=' in line:
           j.write(line)
    j.close()
    te = open('defs.txt', 'r').read().split()
    sto = open('remove.txt', 'r').read().split()
    print 'skimming down the definition...'
    mar = []
    for t in te:
        if t.lower() in sto:
            mar.append('')
        else: 
            mar.append(t)
    print mar
    str = str(mar)
    str = ''.join([ c for c in str if c not in (",", "'", '[', ']', '')])
    defin = open(den, Mod)
    defin.write(str)
    defin.write('                 ')
    defin.close()
    print 'cleaning up...'
    o.system('del dic1.txt')
    o.system('del defs.txt')
Dict(z, 'w')
Dict(b, 'a')
Dict(c, 'a')
Dict(x, 'a')
Dict(m, 'a')
print 'all of the definitions are in definitions.txt'

第一次Dict(z, 'w')工作，然后第二次出现错误：

Traceback (most recent call last):
  File "C:\Users\test.py", line 64, in <module>
    Dict(b, 'a')
  File "C:\Users\test.py", line 52, in Dict
    str = str(mar)
TypeError: 'str' object is not callable

有人知道为什么是这样吗？

我已经尝试过了，但出现错误：

Traceback (most recent call last):
 File "C:\Users\test.py", line 63, in <module>
    Dict(z, 'w')
  File "C:\Users\test.py", line 53, in Dict
   strr = ''.join([ c for c in str if c not in (",", "'", '[', ']', '')])
TypeError: 'type' object is not iterable

回答：

这就是问题：

global str
str = str(mar)

你正在重新定义什么str()意思。str是字符串类型的内置Python名称，你不想更改它。

为本地变量使用其他名称，然后删除该global语句。
