If the old domain is found, then the function returns true. ./script.py Copied! output_file.close() (The blood should not be allowed to dry to a brown color, as this will result in an inaccurate reading.) Now, grant the executable permission to the dailysync.py Python script for running Congratulations! address = re.sub(old_domain_pattern, new_domain, address) You can change this to view other types of logs such as INFO and WARN. old_domain_email_list = [] This function will search and return a list of errors that would be stored in the variable returned_errors. In this case, we are first going to read data from the list (which is a CSV file). Because the colors on the scale represent 1percent variations in hemoglobin content, it may be necessary to estimate the percentage if the color of your blood sample is intermediate between two color standards. Later in the script, we'll iterate over this user input and the log file to produce results. Copied! user_data_list = list(csv.reader(f)) In this section, we will write the body of the function named contains_domain.
