如何在随机数矩阵中隐藏单词

Question

我是一个Python初学者，我被困在这里。我编写了下面的程序，生成一个随机数矩阵。

def randsq(size):
    for i in range(size):
        for j in range(size):
            print(random.randint(0,9), end = '')
        print()

无论如何，我可以添加一个函数，从输入参数中获取一个单词，并在矩阵中对角线隐藏它?所以如果用户输入'rain'，输出看起来像这样:

r123
1a45
23i4
989n

谢谢!

修改代码:

import random
def randsq(word):
    size = len(word)
    for i in range(size):
        for j in range(size):
            if i == j:  # we are at a diagonal-value
                print(word[i], end='')  # it's the i-th diag -> choose i-th char
            else:
                print(random.randint(0, 9), end='')
        print()
randsq('Rain')

输出:

R757
0a91
02i9
757n

如果你想让用户输入这个单词:

word_to_hide = input('Which word to hide? (+enter) ')  # will wait for user-input + enter
randsq(word_to_hide)
