Problem 1 (Analyzing Student Database) The student_info.txt file (available on cuLearn) contains information for many randomly-generated students. The student information follows the structure given below: Student1_first_name Student1_last_name Student1_serial_number Student1_assignment_grade Student1_midterm_grade Student1_exam_grade Student2_first_name Student2_last_name Student2_serial_number Student2_assignment_grade Student2_midterm_grade Student2_exam_grade Download the student_info.txt and t6_p1.py files and put it in the same directory. If you accidentally introduce an error into the data file (i.e., break the structure some how), you can redownload it to get a fresh copy. Add the following functions to t6_p1.py file. Write and test a function called store_results(in_filename, out_filename) that takes two string input parameters for input filename and output filename. You function should read each student’s information from the in_filename (text…
