What are some examples of log data validation in Python?

Log data validation in Python can involve checking for correct formats, missing values, and consistency. Would you like to see specific code examples?

Yes, please provide a code example for checking log format.

Here's a simple example:

import re

def validate_log_format(log_line):
    pattern = r'\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2} - .*'
    return re.match(pattern, log_line) is not None

log_line = '2023-10-01 12:00:00 - Log message'
print(validate_log_format(log_line))  # Output: True

What about checking for missing values in the log data?

You can check for missing values using pandas. Here's an example:

import pandas as pd

log_data = pd.DataFrame({'timestamp': [None, '2023-10-01 12:00:00'], 'message': ['Log message', None]})
missing_values = log_data.isnull().sum()
print(missing_values)
