I wrote the code for these two programs and I keep getting name error for both. Don't understand what I am doing wring.

Part B The dataset file in assets/grades.txt contains a line separated list of people with their grade in a class. Create a regex to generate a list of just those students who received a B in the course. In ! ): import re def grades(): with open ("assignments assignment1/assets/grades.txt, "r") as file: grades = file.read() # YOUR CODE HERE #()" in regex matches any words before "B" result = re.findall(..): B", grade) return result #return result print(grades) raise Not implementedError) En 1: assert len(grades()) - 16 Part C Consider the standard web log file in acetoogdata.xt. This file records the access a user makes when visiting a web page (like this one). Each one of the log has the following items: a host(e.g. 146.204.224.152') . a username (e.g, feest6811 note: sometimes the user name is missing in this case, use as the value for the username.) the time a request was made leg., 21/Jun 2019:15:45:24 -0700') DOO LE en The following cell failed: assert len(grades() == 16 NameError Traceback (most recent call last) in ----> 1 assert len(grades()) == 16 NameError: name 'grades' is not defined U The following cell failed: assert len(logs) == 979 one_item={'host': '146.284.224.152', 'user_name': 'feest6811', 'time': '21/Jun/2019:15:45:24 -0700', 'request': "POST /incentivize HTTP/1.1"} assert one_item in logs(), "Sorry, this item should be in the log results, check y our formating" NameError Traceback (most recent call last) in 1 assert len(logs() == 979 2 3 one_item={'host': '146.204.224.152', "user_name': 'feest6811', 5 time': '21/Jun/2019:15:45:24 - 0700', 4 NameError: name 'logs' is not defined Part C Consider the standard web log file in assets/logdata.txt.
