Python3练习题 018:打印星号菱形
Python的内置方法 str.center(width [, fillchar]) 就能轻而易举打印出来:str即是数量不等的星号,width即是最大宽度(7个空格),默认填充字符fillchar就是空格。两个for循环搞定!代码如下:
1
2
3
4
5
|
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 )) |
方法二
s
=
'*'
for
i
in
range
(
1
,
8
,
2
):
t
=
(
7
-
i)
/

2
print
(
' '
*
t
+
s
*
i
+
' '
*
t)
for
i
in
reversed
(
range
(
1
,
6
,
2
)):
t
=
(
7
-
i)
/

2
print
(
' '
*
t
+
s
*
i
+
' '
*
t)
