本文旨在使用Python的time() 模块打印模式。
例子：
Input :
5
Output :
5 patterns using time with 5 rows
Input :
4
Output :
5 patterns using time with 4 rows, but for diamond if you
will enter even number of rows, it will automatically do (row+1)
代码：生成模式的Python程序
# Print triangles by giving the number of stars:
# For Diamond, an odd number of stars will give a better result,
# If the number is even then for diamond pattern,
# it will automatically do (row + 1):
import time
n = 5
