如何拆分字符串并删除每第n个元素？

def split_and_remove_nth(string, delimiter, n):
    # Step 1: Split the string into a list
    elements = string.split(delimiter)
    
    # Step 2: Remove every nth element
    count = 1
    index = 0
    while index < len(elements):
        if count % n == 0:
            del elements[index]
        else:
            index += 1
        count += 1
    
    # Step 3: Join the modified list into a new string
    new_string = delimiter.join(elements)
    
    return new_string

string = "apple,banana,orange,grape,kiwi"
delimiter = ","
n = 2

new_string = split_and_remove_nth(string, delimiter, n)
print(new_string)

apple,orange,kiwi
