下面提到的是用于打印双面楼梯图案的python 3程序。
null
例如:
Input : 10 Output : * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
注: 此代码仅适用于偶数n值。
# Python3 Program to demonstrate # staircase pattern # function definition def pattern(n): # for loop for rows for i in range ( 1 ,n + 1 ): # conditional operator k = i + 1 if (i % 2 ! = 0 ) else i # for loop for printing spaces for g in range (k,n): if g> = k: print (end = " " ) # according to value of k carry # out further operation for j in range ( 0 ,k): if j = = k - 1 : print ( " * " ) else : print ( " * " , end = " " ) # Driver code n = 10 pattern(n) |
输出:
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
