Question

这是一个魔术方块程序，可以找出任何大小的矩阵是否是魔术方块。当我运行代码时，我得到错误TypeError：＆＃39; int＆＃39;对象不可订阅。我决定将line = int（i）更改为line = i，但这只是给了我另一个错误。不能使用numpy

编辑：现在我收到此错误TypeError：＆＃39; int＆＃39;对象不可迭代

这是代码：

def main():
    filNam = "matrix8.txt"
    matrix = (readMatrix(filNam))
    rowNum = 0
    colNum = 0
    print(rowSum(matrix, rowNum))

def readMatrix(filNam):
    matrixList = []
    numFile = open(filNam, "r")
    lines = numFile.readlines()
    for line in lines:
        line = line.split()
        row = []
        for i in line:
            row.append(int(i))
        matrixList.append(row)
    return matrixList

def eachNumPresent(matrix):
    if len(matrix) % 2 != 0:
        return False
    else:
        return True

def rowSum(matrix, rowNum):
    for row in matrix[rowNum]:
        row = sum(int(row))
        rowNum = rowNum + 1
    return i


def colSum(matrix):
    length = len(matrix)
    col_rows = 0
    for i in range(length):
        col_rows = col_rows + matrix[i][0]
        return col_rows

main()

问题是矩阵变得扁平化了＃34;进入一个长排。为了解决这个问题，你应该阅读＆amp;逐行构造矩阵。

变化：

def readMatrix(filNam):
    matrixList = []
    numFile = open(filNam, "r")
    lines = numFile.readlines()
    for line in lines:
        line = line.split()
        for i in line:
            line = int(i)
            matrixList.append(line)
    return matrixList

为：

def readMatrix(filNam):
    matrixList = []
    numFile = open(filNam, "r")
    lines = numFile.readlines()
    for line in lines:
        line = line.split()
        row = []  # 1st change
        for i in line:
            row.append(int(i)) # 2nd change
        matrixList.append(row) #3rd change
    return matrixList

更改代码并在问题中提供的输入上运行它打印2，这是矩阵中第一行的总和。
