I want to return a function which gives the average of all the marks which are 50 or more. When I run my code, it always returns an empty list. Here is what I have tried:

`def get_pass_average(marks): average = [] for count in marks: if count >= 50: average = sum(count) / len(count) return round(average,2) def test_get_pass_average(): list1 = [50, 83, 26, 65, 92, 29, 77, 64] print('%.2f' % (get_pass_average(list1))) `

Please helps me to figure out the problems in my code, and the output should be 71.83. Many thanks.

Try this:

`l=[i for i in list1 if i>=50] print(sum(l)/len(l)) `

Or:

`from statistics import mean l=[i for i in list1 if i>=50] print(mean(l)) `

If want to condition for empty lists:

`l=[i for i in list1 if i>=50] if l: print(sum(l)/len(l)) `

Or:

`from statistics import mean l=[i for i in list1 if i>=50] if l: print(mean(l)) `
