Pythonic Script That Ignores Timestamps In Log Files

There are 2 log files : log A and log B. log A 2015-07-12 08:50:33,904 [Collection-3]INFO app -Executing Scheduled job: System: choppa1 2015-07-12 09:56:45,060 [Collection-3] INF

Solution 1:

I would  change pat = re.compile("^[^0-9]")

             to pat = re.compile("\d{4}-d{2}-d{2}

and also it is better to open files

withopen(filename) as f:

this way python will close file for you, no need for close(f) statement.

Solution 2:

Here is the small script to eliminate timestamp from the beginning of the file.

program = open("log1.txt", "r")
program_contents = program.readlines()
program.close()

program = open("log2.txt", "r")
program_contents1 = program.readlines()
program.close() 

for i in range(0,len(program_contents1)):
    if program_contents[i] == '\n':
        continueif program_contents[i][19:] == program_contents1[i][19:]:
        print("Matches")
