FIX THE ERRORS IN THE CODE EXERCISE

Here is a program on calculating grades. Please correct the errors in the program.
# Calculating Grades (ok, let me think about this one)
# Write a program that will average 3 numeric exam grades, return an average test score, a corresponding letter grade, and a message stating whether the student is passing.

# Average Grade
# 90+ A
# 80-89 B
# 70-79 C
# 60-69 D
# 0-59 F
# Exams: 89, 90, 90
# Average: 90
# Grade: A
# Student is passing.
# Exams: 50, 51, 0
# Average: 33
# Grade: F
# Student is failing.
exam_one = int(input("Input exam grade one: "))
exam_two = input("Input exam grade two: "))
exam_3 = str(input("Input exam grade three: "))
grades = [exam_one exam_two exam_three]
sum = 0
for grade in grade:
sum = sum + grade
avg = sum / len(grdes)
if avg >= 90:
letter_grade = "A"
elif avg >= 80 and avg < 90
letter_grade = "B"
elif avg > 69 and avg < 80:
letter_grade = "C'
elif avg <= 69 and avg >= 65:
letter_grade = "D"
elif:
letter_grade = "F"
for grade in grades:
print("Exam: " + str(grade))
print("Average: " + str(avg))
print("Grade: " + letter_grade)
if letter-grade is "F":
print "Student is failing."
else:
print "Student is passing."
Fixed:
