Question

我正在编写一个自动化脚本来提取与日志文件中第一个字符串（inputName）匹配的行，如果在该行中找到该特定匹配项，则在该特定行中搜索第二个字符串（successful_msg），其中显示“文件已上载成功”。

以下是代码：

import re

successful_msg="file has been uploaded"
def log_check(fileName):
     search_fileName = fileName
     print search_fileName
     with open("/tmp/test.log") as line:
         for match in line:
                 m=re.search(r"%s" %search_fileName, match)
                 n=re.search(r"%s" %successful_msg,match)
                 if m and n:
                      print match
                 elif m:
                      print "File not updated"
                 else:
                      print "File is not processed"

 for inputName in glob.glob('./files/*'):
    log_check(inputName)

我能够从“if m and n：”行获得成功的消息。但是，如果我包含“其他”，我只会看到“文件未处理”，即使第一个如果通过。逻辑错在哪里？

例如：ls files/

abc-15  abc-16  abc-123  gg

我想要的输出应该是：

abc-15 
2015-03-17 06:09:26.122  INFO --- *** : The /tmp/test/abc-15 file has been uploaded
abc-16
2015-03-17 06:08:42.692  INFO --- *** : The /tmp/test/abc-16 file has been uploaded
gg
File is not processed
abc-123
File not updated

在循环中取消注释/考虑else时的实际结果是：

gg
File not updated
abc-15
File not updated
abc-16
File not updated
abc-123
File not updated

当评论其他时，结果是：

gg
abc-15
2015-03-17 06:09:26.122  INFO ---*** : The /tmp/test/abc-15 file has been uploaded
abc-16
2015-03-17 06:08:42.692  INFO --- *** : The /tmp/test/abc-16 file has been uploaded
abc-123

我建议您对def进行以下更改，并附上我的评论：

import re

successful_msg="file has been uploaded"
def log_check(fileName):
     search_fileName = fileName
     print search_fileName
     with open("/tmp/test.log") as line:
         # New variable to determine if fileName is matched or not
         matched = 0
         for match in line:
                 m = re.search(r"%s" %search_fileName, match)

                 # If fileName found, update above variable
                 if m:
                      matched = 1

                 n=re.search(r"%s" %successful_msg,match)

                 # On any line, if both phrases are present on the same line:
                 if n and m:
                      print match
                      break

         # If for loop exited without break...
         else:
              # If we found the filename...
              if matched == 1:
                  print "File not updated"
              # If even the filename was not found...
              else:
                  print "File is not processed"



for inputName in glob.glob('./files/*'):
    log_check(inputName)

Python中的多个字符串匹配
