Question

我有以下代码从URL列表中下载HTML内容。每当我运行它时，我会收到一条错误消息“Traceback（最近一次呼叫最后一次）：

tan()

这是代码：

test:
    [junit] Running CalculatorTest
    [junit] Testsuite: CalculatorTest
    [junit] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 se

    [junit] CalculatorTest (wrong name: package/CalculatorTest)
    [junit] java.lang.NoClassDefFoundError: CalculatorTest (wrong name: package/C
alculatorTest)

我该如何解决这个问题？

您正在尝试在函数上调用方法而不是对象。而是致电：

import hashlib
from hashlib import md5
import os

fh = open("****.txt", 'r')

for line in fh:
     url = line
     url = url.replace('\n', '')

     def computeMD5(message):
        m = hashlib.md5()  # instead of m = hashlib.md5
        m.update(message)
        return m.hexdigest()

    hashMessage = computeMD5(url)
    print hashMessage

    os.system(" wget -O /desktop/Html" + hashMessage + ".txt " + url)

AttributeError：...对象没有属性'update'
