Question

我正在使用此代码尝试为包含关键字的日志文件提取行。但是，我知道包含这些单词的文件和行不会写入新的错误文件。

我原本以为我的问题是因为Windows和Linux之间的终端字符不同但我从这些原始文件中删除了行，因此警告是文件中的第一个单词。这些行仍未添加到错误文件中。

我创建了自己的文件，其中填写了随机文字和“警告”字样。在几个地方，并正确输出。我使用了正则表达式，它们对情况没有影响。一旦我开始工作，我会将其转换为使用正则表达式。

任何帮助都会很棒，甚至可以指向解决方案。

def errorSearch(filename):
    errorfile = "error" + filename
    print(errorfile)
    try:
            fileopen = open(filename, "r")
            errorfileopen = open(errorfile, 'w')
            runtest(fileopen, errorfileopen)

            return 1
    except IOError:
            print ("Error: File does not appear to exist.")
            return 0

def runtest(logfile, error):
    num = 0
    for line in logfile:
            if 'Warning' in line:
                    error.write(line)
                    num+=1
    print(num)


errorSearch("log.txt")

日志文件代码示例适用于复制和粘贴代码，但不适用于原始文本：

只需添加strip命令即可过滤掉可能与if语句混淆的垃圾字符。

length

另外，请记得关闭错过文件句柄。
