for grade in test_grade

All of the math concepts are familiar to me, The part I am lost with is where - for grade in test_grade: - somehow pulls the proper number of grades above 70. Is grades a specified term? is it a part of the code that I am not seeing? the percentages and math all make sense, I am just unaware what is telling this to go up and look for this properly.

thanks!

Are you familiar with for loops?

for grade in test_grades:
    if grade >= 70:
        passed += 1

This is an example of a for loop in Python; grade is just used as a reference to each item in the test_grades list. First time through the loop, grade would equal 98 because that's the first item in the list for example. Second time, grade would equal 100, third time 54, etc.
