How can I parse log files in Python?

You can use the built-in open() function to read log files and then process each line. Would you like a code example?

Yes, please provide a simple code example.

Sure! Here's a basic example:

with open('logfile.log', 'r') as file:
    for line in file:
        print(line.strip())

This reads each line from 'logfile.log' and prints it without extra whitespace.

How can I filter specific log entries?

You can use an if statement to check for specific keywords. For example:

with open('logfile.log', 'r') as file:
    for line in file:
        if 'ERROR' in line:
            print(line.strip())

This will print only the lines containing 'ERROR'.
