i am getting an error "Code is unreachable Pylance" what that mean or am i doing any mistake in my code?

def percent(marks):
    return (marks[0]+marks[1]+marks[2]+marks[3]/400)*100

    marks1=[54,65,85,54]
    percent1=percent(marks1)

    marks2=[54,52,65,85]
    percent2 = percent(marks2)
    print(percent1,percent2)

Solution

The lines after return will not be executed anytime. So you can delete them and nothing will change. The message told you about it, because it is very unusual to have such code.

I think you wanted this:

def percent(marks):
    return (marks[0]+marks[1]+marks[2]+marks[3]/400)*100

marks1 = [54, 65, 85, 54]
percent1 = percent(marks1)

marks2 = [54, 52, 65, 85]
percent2 = percent(marks2)
print(percent1, percent2)

Spaces in Python code matter. In your code all lines are the part of the function. In fixed code they are not.
