如何根据用户输入构建矩阵？

Question

如何解决用随机数（用户输入）创建矩阵的问题？ 我也有这个问题：

UnicodeDecodeError: 'ascii' 编解码器无法解码位置上的字节 0xc3 23: 序数不在范围内(128)

array = list()
i = int(input("How many row: "))      
j = int(input("How many column: "))    


for x in range(i):                
    if i <= 0 or i>10:
        print("Failure!")  
        break
    elif j <= 0 or j>10:
        print("Failure!")
        break
    else:
        for y in range(j):        
            num = raw_input("Value: ")       
            array.append(int(num))


a = np.reshape((i,j))
print a

我将np.reshape((i,j)) 更改为a = np.reshape(array,(i,j))，它工作正常。我没有看到你提到的代码中有任何错误。

import numpy as np
array = list()
i = int(input("How many row: "))
j = int(input("How many column: "))


for x in range(i):
    if i <= 0 or i>10:
         print("Failure!")
         break
    elif j <= 0 or j>10:
         print("Failure!")
         break
    else:
        for y in range(j):
             num = raw_input("Value: ")
             array.append(int(num))


a = np.reshape(array,(i,j))
print a
