向后循环，创建菱形图案

def create_diamond_pattern(n):
    for i in range(n):
        for j in range(n - i - 1):
            print(" ", end="")
        for j in range(i + 1):
            print("* ", end="")
        print()
    
    for i in range(n - 2, -1, -1):
        for j in range(n - i - 1):
            print(" ", end="")
        for j in range(i + 1):
            print("* ", end="")
        print()

# 调用函数创建一个大小为5的菱形图案
create_diamond_pattern(5)
