Theory for this problem
+
`input()` reads data entered by the user. The result of `input()` is initially a string. `split()` separates one input line into individual values using spaces. `map()` applies the specified conversion to each input value. The `+` operator adds numbers. The `/` operator performs regular division and may return a decimal number. Comparison operators `==`, `!=`, `<`, `>`, `<=`, `>=` compare values and produce `True` or `False`. `if` checks a condition and runs its block when the condition is true. `else` runs when the corresponding `if` condition is false. `print()` displays the program result. Print only what the problem statement requires.
**Connection to this task.** An `if` statement chooses a program branch from a Boolean condition. Comparisons produce `True` or `False`, and `elif` lets you test several mutually exclusive cases in order. The expression `avg` shows how this idea is applied to the task data.

ANSWER
Solution
+
a, b, c = map(float, input().split())
avg = (a + b + c) / 3
if avg >= 90:
s = 'EXCELLENT'
elif avg >= 75:
s = 'GOOD'
elif avg >= 60:
s = 'PASS'
else:
s = 'FAIL'
print(avg, s)
