Python 旋转矩阵环的第一行出现错误

在这段代码中，我得到了下面的错误

Enter M: 
Traceback (most recent call last):
  File "main.py", line 1, in <module>
    M = int(input("Enter M: "))
ValueError: invalid literal for int() with base 10: '4 4'

请帮助我找到python专家。

输入数据的代码（问题的输入部分）：

输出

---

如果我理解正确，请任何人帮助我，您试图通过空格一次输入两个数字，而不是通过enter一次输入一个。要用一个输入输入两个数字，您可以这样做：

M，N=[int（x）for x in Input（输入M N:）.split（“”）]
