I can't get my lab to work. Now, run the file by passing the path to fishy.log as a parameter to the script. The function contains_domain should now look like this: def contains_domain(address, domain): Storing all domain names, including the updated ones, in a new file. Since the function contains_domain takes in email address passed as parameter, we will iterate over the user_email_list to pass email addresses one by one. if name == "main": In the final course, we'll tie together the concepts that you've learned up until now. For every matched email address, we will append it to the list old_domain_email_list. Please help me with the week 2 assignment of troubleshooting and debugging techniques course of coursera. Navigate to the data directory using the following command: cd data Qwiklabs-Assessment-Automating-Real-World-Tasks-with-Python. old_domain_pattern = r'' + old_domain + '$' error_patterns = ["error"] is similar to the path /home//data. No description, website, or topics provided. In this case, we'll search for a CRON error within the fishy.log file that failed to start by narrowing our search to "CRON ERROR Failed to start". This file already has the functions defined for you. To get started, let's create a python script named find_error.py within scripts directory using nano editor. If it is an integer, zero is considered "successful termination" and any nonzero value is considered an "abnormal termination" by shells. An example of data being processed may be a unique identifier stored in a cookie. Qwiklabs Assessment: Working with Regular Expressions. Create an output file To find the data, list the files using the following command: ls Also, give a file path for the resulting updated list within the variable report_file. if re.match(domain,address): from multiprocessing import Pool . In the previous sections, you might have seen variables named old_domain and new_domain, which are passed as parameters to the functions. (Python is a cross-platform language.
