在日志文件行中搜索多个关键字并找到返回错误字符串

Question

I'm trying to create this program which opens up a .gz file and looks for multiple exceptions. It was working when I just used one exception. But I am now trying to get multiple exceptions, and it is not working.

Can anyone help?

import gzip
with gzip.open((raw_input("Enter File Name :")), 'r') as f:
     x1 = ['REBINFO', 'cocaLc']
     y1 = [False, False]
     x2 = ['dispute', 'peer', 'while', 'priority']
     y2 = [False, False, False, False]
     x3 = ['task cocaLc ASSERT failed', 'fhAssert', 'REBINFO', 'HARDREBOOT', '09.']
     y3 = [False, False, False, False, False]
     for line in f:
         for i in range(0, len(x1)):
             if (x1, x2, x3) [i] in line: #loop through x1, x2, x3 using index numbers
                 y1[i] = True
                 y2[i] = True
                 y3[i] = True

 if all(y1): #if every search string was detected, every value in y1 should be true
     print "Exception Found : " + "task cocaLc Requested reboot"
 if all(y2): #if every search string was detected, every value in y2 should be true
     print "\nException Found : " + "task tAlrmL1 Keep alive failed"
 if all(y3): #if every search string was detected, every value in y3 should be true
     print "\nException Found : task cocaLc ASSERT failed"

I believe this code meets your problem statement. Two key changes from your code.

1. Put error message and keywords to search for together in the same data structure.

2. Loop over the data structure and directly determine if all keywords are present, and if not store the error message for later display

Please note: I did not actually test this code, as I had no sample data.

Code:

import gzip

errors_to_find = (
    ('task cocaLc Requested reboot', 
     ('REBINFO', 'cocaLc')),
    ('task tAlrmL1 Keep alive failed',
     ('dispute', 'peer', 'while', 'priority')),
    ('task cocaLc ASSERT failed', 
     ('fhAssert', 'REBINFO', 'HARDREBOOT')),
)

found_exc = []
with gzip.open((raw_input("Enter File Name :")), 'r') as f:
    for line in f:
        for msg, key_words in errors_to_find:

            # for each keyword, test if it is in line 
            if sum([kw in line for kw in key_words]) == len(key_words):
                found_exc.append(msg)

for msg in found_exc:
    print "Exception Found : %s" % msg
