Question

我不知道该怎么做，我有一个39行的Python脚本，它在第40行给我一个错误！ :(错误：

Traceback (most recent call last):
File "C:\Mass Storage\pythonscripts\Internet\execute.py", line 2, in <module>
execfile("firstrunSoup.py")
File "firstrunSoup.py", line 40

                                ^
SyntaxError: invalid syntax

C:\Mass Storage\pythonscripts\Internet>

这是我的Python代码：

###firstrunSoup.py###
FILE = open("startURL","r") #Grab from
stURL = FILE.read() #Read first line
FILE.close() #Close
file2save = "index.txt" #File to save URLs to

jscriptV = "not"
try:
    #Returns true/false for absolute
    def is_absolute(url):
        return bool(urlparse.urlparse(url).scheme)

    #Imports
    import urllib2,sys,time,re,urlparse
    from bs4 import BeautifulSoup

    cpURL = urllib2.urlopen(stURL) #Human-readable to computer-usable
    soup = BeautifulSoup(cpURL) #Defines soup

    FILE = open(file2save,"a")
    for link in soup.find_all('a'): #Find all anchor tags
        outPut = ""
        checkVar = link.get('href') #Puts href into string
        if (checkVar is not None) and (checkVar != ""): #Checks if defined
            if len(checkVar) > 11: #Check if longer than 11 characters
                if checkVar[:11] != "javascript:": #Check if first 11 are "javascript:"
                    if checkVar[:7] != "mailto:": #Check if first 7 are "mailto:"
                        jscriptV = "not"
                    else: jscriptV = ""
                else: jscriptV = ""
            if checkVar != "#" and checkVar != "/":
                if jscriptV == "not":
                    if checkVar is not None: #Checks if defined
                        if is_absolute(checkVar): outPut = checkVar.split("#")[0]
                        else: outPut = urlparse.urljoin(stURL,checkVar).split("#")[0]
                    if outPut != "":
                        print outPut
                        FILE.write(outPut + "\r\n")
                        FILE.close()
execfile("nextrunsSoup.py")

如果你能帮助我，请做。到目前为止，我已经花了很多时间，当它终于准备好了，我明白了。提前谢谢！

Answer 1

除了您的行程之外，您没有匹配>

Answer 2

在except之后和行

之前应该有一个try块

execfile("nextrunsSoup.py")

Answer 3

因此，您的文件正文包含在try:中，而您的except:或finally:位于哪里？

不存在的行Python出错
