#Student grades manager python text file code
Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. Print 'name: %(name)s | grades: %(grades)s | average: %(avg)0.Python is an interpreted high-level programming language for general-purpose programming. Print 'class average: %0.2f' % mean(student_means.values())įor name, grades in student_eritems(): Student_means = dict((k, mean(v)) for k, v in student_eritems()) Student_grades = import_student_grades(grades_file) Return dict((words, words) for words in line_words) Given a filename, reads data into a dict whose keys are student namesĪnd whose values are grades (as strings). Return sum(map(float, list)) / len(list) \ I've taken out the non-essential prompt for the number of assignments you can easily put it back. Don't do that - student_means() should just return a fresh dict instead. The main objection I had to your code was that you mangled the data structure by appending each student's average at the end of his grades. Once you do that, the calculations themselves are one-liners. In this problem, it is very important to define a mean() function. Print 'name: %s | grades: %s | average: %s' % (k, grades, avg)įor conciseness in Python, the key is to think in terms of applying functions using map and list comprehensions, rather than thinking procedurally. Grades = ' '.join(str(i) for i in grades) Student_data_avg = student_means(student_data)įor k, v in student_data_avg.iteritems(): Student_data = import_data(grades_file, assignments) Grades_mean = float(sum(item for item in grades)) / len(grades)įor k, v in student_grades_eritems():Ĭlass_mean = float(sum(item for item in class_grades)) / len(class_grades)Īssignments = int(raw_input('How many assignments are there? ')) """Generate the average grade for each student and append it.""" """Split the data into key value pairs.""" Grade_avg_generator.py """Simple student grade manager"""ĭef import_data(grades_file, assignments): Can you give me tips on "pythonic" ways to simplify the script? While my solution works, it seems awfully verbose. The user is then asked how many assignments there are. It is formatted like so: JON 19 14 15 15 16 I wrote up a simple averages calculator for student grades, based on this daily programming challenge.įirst, the script asks for the file name for the text file containing the student names and grades.
