Write a Python code that gets a file name from a user using the input statement

ANSWER ALL QUESTIONS

HOMEWORK #3

1. (55 points) Write a Python code that gets a file name from a user using the input statement and reads it to obtain information about students. Each line of the file includes information about a different student and has two items separated by a space character. A file, grades.dat, that includes the names and grades of 10 students as shown below is given as an example. The first item is the student name and the second item is the grade of that student. The code will read the information in the file in a dictionary where student names are keys and their grades are values. The second item in each line that represents a grade will be converted to float when it is read as a value in the dictionary. The code is expected to print the names and grades of the students after reading them. A grade is considered success if it is 70 or above, and failure if it is below 70. The code will count the number of successes, numSuccesses, and the number of failures, numFailures. It will print successFailure Ratio, which is numSuccesses divided by numFailures.

2. Please submit only one zip me including only Python codes with .py extension. There will be a separate .py file for each question in the zip file. Submissions in other formats will not be accepted. Name your Python codes as lastname1.py, lastname2.py, and so on.

3. Codes are expected to be clear, legible and compact with minimum number of lines and variables, and proper indentation. Variable names are expected to be appropriate, meaningful and self-explanatory. Codes will be graded based on these criteria. A correctly working code does not guarantee full credit.

4. If your Python code works with files, do not use file paths or commands specific to your computer. Your code is supposed to work on another computer as it is.
