python question

2. In a file called passfail.py, write a Python program to solve the following problem: Given a file students.txt with the following information for a stu dent: student number, average quiz mark, average assignment mark, midterm exam mark, and final exam mark (where each mark is recorded out of 100), de termine if the student has passed or failed based on the following information: • A student will pass the course if they have a passing mark (50% or higher) for the average quiz mark and for at least one of the two exam marks (midterm or final). • A student will also pass the course if they have a passing mark for the average assignment mark and for both of the exam marks (midterm and final) Output each student's student number and the semester's result (pass or fail) to the screen. Write to a file called pass.txt the student numbers of only those students who have passed. Your program should also include exception handling to deal with a missing students.txt file, as well as missing student information (for example, a missing exam mark). For both types of exceptions you can simply print a message to indicate the problem, and your code can terminate. Submit your input and output file with your program. Given the following input file, students.txt, 1111 85 65 89 90 2222 55 45 67 85 3333 45 55 67 85 4444 45 55 47 85 5555 55 45 47 85 6666 45 55 85 47 7777 55 45 85 47 8888 45 46 47 48 9999 45 45 67 67 the output from the program is, stnum: 1111 result: pass stnum: 2222 result: pass stnum: 3333 result: pass stnum: 4444 result: fail stnum: 5555 result: pass stnum: 6666 result: fail stnum: 7777 result: pass stnum: 8888 result: fail stnum: 9999 result: fail and the content of the output file pass.txt is:
