正方向
height = int(input("please input height: ")) tmp = 1
while tmp <= height:
width = tmp
while width > 0:
print("*", end="")
width -= 1
print("")
tmp += 1
测试结果:
反方向:
height = int(input("please input height: ")) while height > 0:
tmp = height
while tmp > 0:
print("*",end="")
tmp -= 1
print()
height -= 1
