两种使用python打印菱形的方法

1、使用center方法
s = '*'for i in range(1, 8, 2):    print((s*i).center(7))for i in reversed(range(1, 6, 2)):    print((s*i).center(7))

2、使用普通方法
#  coding:utf-8rows = int(input('输入列数： '))i = j = k = 1#  声明变量,i用于控制外层循环（图形行数），j用于控制空格的个数，k用于控制*的个数#  打印菱形print("打印空心等菱形，这里去掉if-else条件判断就是实心的")for i in range(rows):    for j in range(rows - i):        print(" ", end=" ")        j += 1    for k in range(2 * i - 1):        if k == 0 or k == 2 * i - 2:            print("*", end=" ")        else:            print(" ", end=" ")        k += 1    print ("\n")    i += 1    #  菱形的下半部分for i in range(rows):    for j in range(i):        #  (1,rows-i)        print(" ", end=" ")        j += 1    for k in range(2 * (rows - i) - 1):        if k == 0 or k == 2 * (rows - i) - 2:            print("*", end=" ")        else:            print(" ", end=" ")        k += 1    print("\n")    i += 1
