Question

我尝试使用while循环写入一系列新文件。循环的每次迭代都应该写入一个新文件，并在下一个循环开始之前关闭它。我使用的是Python 2.7，我想解决这个问题而不必在可能的情况下安装任何其他库。

我已经让程序用于写入单个文件，但是一旦我尝试使用循环，程序就会无限循环，一遍又一遍地写入初始文件。它不会关闭第一个文件并转移到下一个循环。这是代码：

更新：问题已解决。我将while循环中的所有内容移动到一个单独的函数中，并在while循环中重复调用它，同时递增参数的chapter值。还要确保在箭头括号和大写字母P中考虑小写字母P.感谢大家的帮助！

import urllib

storyID = raw_input("Please Enter Story ID: ")
chapters = raw_input("Please Enter the number of Chapters: ")
countDown = int(chapters)
countUp = 1

while countUp <= countDown :

    storyURL = "https:website/" + storyID + "/" + str(countUp) + "/"
    f = urllib.urlopen(storyURL)

    with open ('chapter' + str(countUp) + '.html', 'a') as g:

        bof = False
        eof = False


        while eof == False :
            line = f.readline()
            if "<P>" in line and bof == False :
                bof = True
                g.write("""<html>\n<meta charset='utf-8'>\n
                <META NAME='ROBOTS' CONTENT='NOARCHIVE'>\n
                <META http-equiv='X-UA-Compatible' content='IE=edge'>\n
                <META NAME='format-detection' content='telephone=no'>\n

                g.write(line)

            elif "Chapter Navigation" in line and bof == True:
                eof = True
                g.write ("</html>")

            elif bof == True :
                g.write(line)
    g.close()
    countUp = countUp + 1

Answer 1

案件很重要。

countUp = countUp + 1

更好的是：

countUp += 1

Answer 2

TRY THIS WAY....when you fetch the url use read() method first
################
import urllib

storyID = raw_input("Please Enter Story ID: ")
chapters = raw_input("Please Enter the number of Chapters: ")
countDown = int(chapters)
countUp = 1

while countUp <= countDown :

    storyURL = "https:website/" + storyID + "/" + str(countUp) + "/"
    f = urllib.urlopen(storyURL)
    data = f.read()

    with open ('chapter' + str(countUp) + '.html', 'w') as g:
          g.write(data)

    countUP = countUp + 1
