Input in Python:

• For integers use: int(input("user prompt "))
• For floats use: float(input("user prompt "))
• For strings use: input("user prompt ") and when inputing the string you must enclose it in double or single quotes
• For formatted output use function format.
  • For example, to print only 2 decimal digits of the number 1232.566777 use the following statement:

    print(format(1232.566777, '.2f'))

  • For example, to print only 4 decimal digits of the number 1232.566777 use the following statement:

    print(format(1232.566777, '.4f'))

3. A student took four courses in Fall 2019 semester. Write a program that asks user to enter final grade for each course in Fall 2019 and finds the average grade for Fall 2019 semester.

4. The final grade in our course is calculated according to the following rule:

   Final Grade

   Laboratory Sessions	45%
   Exams	35%
   Mini-Quizzes	15%
   Homework and Attendance	5%

   Write a program that asks user to enter the average grade for all quizzes, average grade for all exams, average grade for all homeworks, and the lab grade. The program calculates the final grade in the course.
