How can i have the output of this program-CodePudding

def getLetterGrade(score):
    score = round(score)
    grades = [(90, 'A'), (80, 'B'), (70, 'C'), (60, 'D'), (0, 'F')]
    for i in range(len(grades)):
        if score >= grades[i][0]:
            return grades[i][1]

I found this for grading system. I tried to output by getLetterGrade(score) at the end but it's not showing any result, and I don't know why.

You'll need to pass in a variable of type int, and make sure you call the print() function to print out the returned result of type str:

def getLetterGrade(score):
    score = round(score)
    grades = [(90, 'A'), (80, 'B'), (70, 'C'), (60, 'D'), (0, 'F')]
    for i in range(len(grades)):
        if score >= grades[i][0]:
            return grades[i][1]

score = 75
print(getLetterGrade(score))

Output:

First of all you need to indent your code over:

def getLetterGrade(score):
    score = round(score)
    grades = [(90, 'A'), (80, 'B'), (70, 'C'), (60, 'D'), (0, 'F')]
    for i in range(len(grades)):
        if score >= grades[i][0]:
            return grades[i][1]

print(getLetterGrade(80))
B

then all you need to do is PRINT the result of the function. When you return in a function, that isn't printing anything out, so you need to call "print" in order to see the output to the console.
