I am trying to do a board outline with "-" and "+" but I am getting unexpected output

I mentioned the condition to print at particular places but instead of printing at those locations code just appends "+" to "-" even with range condition it exceeds the limit.
I wanted to print "+" at 0, 8, 16, 24 index locations and print "-" in between them.

def display(board):
    for row in range(25):
        print("-", end = "")
        if row == 0 or row == 8 or row == 16 or row == 24:
            print("+", end = "")

The outcome when I invoke the function is:

-+--------+--------+--------+

I tried to modify code so that "+" stays in condition loop when "-" is outside but output is different

def display(board):
    for row in range(25):
        if row == 0 or row == 8 or row == 16 or row == 24: 
            print("+", end = "")
        print("-", end = "")

+--------+--------+--------+-

My expected outcome is supposed to be:

+-------+-------+-------+

>Solution :

You’ve just got to use an if else to only print 1 char per iteration of your loop. Without the else, you are printing twice on each multiple of 8.

def display(board):
    for row in range(25):
        if row == 0 or row == 8 or row == 16 or row == 24:
            print("+", end = "")
        else
            print("-", end = "")

You could also simplify the code and make it a bit more readable using some math.

def display(board):
    for row in range(25):
        if row % 8 == 0:
            print("+", end = "")
        else
            print("-", end = "")
