Question

有人可以帮忙找到一种方法来制作带有嵌套for循环的梯形吗？我做到了，但它不断使需要的星星更多。有人可以给我建议。

import time
row1 = int(input("What is the length of the top side: "))
star = ("*"*row1)
height = int(input("Enter the height of this trapezoid:"))

for row in range(1, height + 1):`
    # print out the right number of spaces
    for spaces in range(1, height - row + 1):
        print(" ", end = "")
        time.sleep(0.5)

    for asterisks in range(row):
        print(star, end = "" )
    print()

您的代码有缺陷，您多次打印星形变量，因此开始次数过多，您需要将星形数增加2，而不是将星形数相乘。

for row in range(height):
    # print out the right number of spaces
    for spaces in range(height - row-1):
        print(" ", end = "")
        time.sleep(0.5)

    for asterisks in range(row1+row*2):
        print('*',end = "" )
    print()

如果不需要time.sleep（），则可以在一个循环中完成。

for row in range(height):
    print(" "*(height-row-1),"*"*(row1+row*2))
