Using Python to Interact with the Operating System WEEK 4 Qwiklabs Assessment Coursera by Google. Welcome to Using Python to Interact with the Operating System. You’re joining thousands of learners currently enrolled in the course. This course is a part of Google IT Automation with Python Professional Certificate. Qwiklabs Assessment : “Working with Log Files”
I’m excited to have you on my channel and look forward to your contributions to the learning community. By the end of this course:
- you’ll be able to manipulate files and processes on your computer’s operating system. You’ll also have learned about regular expressions a very powerful tool for processing text files
- you’ll get practice using the Linux command line on a virtual machine.
And, this might feel like a stretch right now, but you’ll also write a program that processes a bunch of errors in an actual log file and then generates a summary file. That’s a super useful skill for IT Specialists to know.
-:Skills you will learn:-
- Setting up your Development Environment
- Regular Expression (REGEX)
- Testing in Python
- Automating System Administration Tasks with Python
- Bash Scripting

Qwiklabs Assessment : “Working with Log Files”
Codes:-
#!/usr/bin/env python3
import sys
import os
import re
def error_search(log_file):
error = input("What is the error? ")
returned_errors = []
with open(log_file, mode='r',encoding='UTF-8') as file:
for log in file.readlines():
error_patterns = ["error"]
for i in range(len(error.split(' '))):
error_patterns.append(r"{}".format(error.split(' ')[i].lower()))
if all(re.search(error_pattern, log.lower()) for error_pattern in error_patterns):
returned_errors.append(log)
file.close()
return returned_errors
def file_output(returned_errors):
with open(os.path.expanduser('~') + '/data/errors_found.log', 'w') as file:
for error in returned_errors:
file.write(error)
file.close()
if __name__ == "__main__":
log_file = sys.argv[1]
returned_errors = error_search(log_file)
file_output(returned_errors)
sys.exit(0)
