编写程序，实现输入整数n，输出由数字组成的三角形（如下图，n=5），并在此基础上修改，使之能输出数字菱形。 + + + +1 + + +1+2+1 + +1+2+3+2+1 1+2+3+4+3+2

以下是Python实现输入整数n，输出由数字组成的三角形和数字菱形的代码：

# 输出数字三角形
n = int(input("请输入一个不大于10的正整数n："))
for i in range(1, 2*n):
    if i <= n:
        for j in range(1, i+1):
            print(j, end=" ")
    else:
        for j in range(1, 2*n-i+1):
            print(j, end=" ")
    print()

# 输出数字菱形
n = int(input("请输入一个不大于10的正整数n："))
for i in range(1, 2*n):
    if i <= n:
        for j in range(1, i+1):
            print(j, end=" ")
    else:
        for j in range(1, 2*n-i+1):
            print(j, end=" ")
    print()
for i in range(1, 2*n):
    if i <= n:
        for j in range(1, n-i+1):
            print(" ", end=" ")
        for j in range(n-i+1, n):
            print(j, end=" ")
        for j in range(n, i+n):
            print(n*2-j+i-1, end=" ")
        for j in range(i+n, 2*n):
            print(" ", end=" ")
    else:
        for j in range(1, i-n+1):
            print(" ", end=" ")
        for j in range(i-n+1, n):
            print(j, end=" ")
        for j in range(n, i):
            print(n*2-j+i-1, end=" ")
        for j in range(i, 2*n):
            print(" ", end=" ")
    print()
