思路 ：创建n*n的一个列表，列表的每一个位等于0 eg: l[2][1] = l[1][1]+l[1][0]
n = eval(input()) l = [[0 for i in range (n)] for i in range (n)] l[0][0]=1 for i in range(1,n): for j in range(n): if j !=0: l[i][j]=l[i-1][j-1]+l[i-1][j] else: l[i][j]=1 for i in range(n): for j in range(n): if l[i][j] !=0: print(l[i][j],end =' ') print()9.查找整数
n = eval(input()) l = list(map(int,input().split())) s = eval(input()) count = 0 for i in range (n): if l[i]==s: print(i+1) break else: print(-1)10.数列特征
