男 | 程序猿一只，喜欢编程写python代码。

我正在尝试使用python创建一个程序，该程序将基于文本文件来决定一个正方形是否是幻方。你知道吗

def getRowsAndColumns(user2DimensionalList):
  numberOfRows = len(user2DimensionalList)
  numberOfColumns = len(user2DimensionalList[0])
  
  return numberOfRows, numberOfColumns

def getFirstRowSum(user2DimensionalList, numberOfColumns):
  firstRowSum = 0
  
  for currentRowIndex in range(1):
    for currentColumnIndex in range(numberOfColumns):
      firstRowSum = firstRowSum + user2DimensionalList[currentRowIndex][currentColumnIndex]

    return firstRowSum

def hasEqualRowSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns):
  rowSum = 0
  
  for currentRowIndex in range(numberOfRows):
    for currentColumnIndex in range(numberOfColumns):
      rowSum = rowSum + user2DimensionalList[currentRowIndex][currentColumnIndex]
    if rowSum != firstRowSum:
      return False
    rowSum = 0
    
  return True

def hasEqualColumnSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns):
    columnSum = 0
    for currentColumnIndex in range(numberOfColumns):
      for currentRowIndex in range(numberOfRows):
          columnSum = columnSum + user2DimensionalList[currentRowIndex][currentColumnIndex]
      if columnSum != firstRowSum:
          return False
      columnSum = 0
    
    return True

def hasEqualRowAndColumnSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns):
  if hasEqualRowSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns) and hasEqualColumnSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns):
       return True
  else:
       return False
     
     
def hasFromLeftEqualDiagonalSum(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum):
  fromLeftDiagonalSum = 0
  
  for currentDiagonalNumberIndex in range(lengthOfAnyRowOrColumn):
    fromLeftDiagonalSum = fromLeftDiagonalSum + user2DimensionalList[currentDiagonalNumberIndex][currentDiagonalNumberIndex]
        
  if fromLeftDiagonalSum != firstRowSum:
    return False
  else:
    return True
  
def hasFromRightEqualDiagonalSum(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum):
    fromRightDiagonalSum = 0
    currentDiagonalNumberColumnIndex = lengthOfAnyRowOrColumn - 1
    
    for currentDiagonalNumberRowIndex in range(lengthOfAnyRowOrColumn):
        fromRightDiagonalSum = fromRightDiagonalSum + user2DimensionalList[currentDiagonalNumberRowIndex][currentDiagonalNumberColumnIndex]
        currentDiagonalNumberColumnIndex = currentDiagonalNumberColumnIndex - 1
    if fromRightDiagonalSum != firstRowSum:
        return False
    else:
        return True
def hasEqualDiagonalSums(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum):
    if hasFromLeftEqualDiagonalSum(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum) and hasFromRightEqualDiagonalSum(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum):
        return True
    else:
        return False

def isLoShuMagicSquare(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns, lengthOfAnyRowOrColumn):
    if hasEqualRowAndColumnSums(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns) and hasEqualDiagonalSums(user2DimensionalList, lengthOfAnyRowOrColumn, firstRowSum):
        return True
    else:
        return False


def main():
    user2DimensionalList = open("input.txt", "r")
    user2DimensionalList = user2DimensionalList.read()
   
    
    
    numberOfRows, numberOfColumns = getRowsAndColumns(user2DimensionalList)
    
    lengthOfAnyRowOrColumn = numberOfRows
    
    firstRowSum = getFirstRowSum(user2DimensionalList, numberOfColumns)
    
    if isLoShuMagicSquare(user2DimensionalList, firstRowSum, numberOfRows, numberOfColumns, lengthOfAnyRowOrColumn):
        print("VALID")
    else:
        print("INVALID")
        
main()

以下是我的txt文件中的内容：

4 3 8 9 5 1 2 7 6
8 3 4 1 5 9 6 7 2
6 1 8 7 5 3 2 9 4
6 9 8 7 5 3 2 1 4
6 1 8 7 5 3 2 1 4
6 1 3 2 9 4 8 7 5
5 5 5 5 5 5 5 5 5

我不知道我做错了什么我得到了这个错误：

Traceback (most recent call last):
  File "/Users/noahhenkle/Desktop/MagicSquare2.py", line 98, in <module>
    main()
  File "/Users/noahhenkle/Desktop/MagicSquare2.py", line 91, in main
    firstRowSum = getFirstRowSum(user2DimensionalList, numberOfColumns)
  File "/Users/noahhenkle/Desktop/MagicSquare2.py", line 12, in getFirstRowSum
    firstRowSum = firstRowSum + user2DimensionalList[currentRowIndex][currentColumnIndex]
TypeError: unsupported operand type(s) for +: 'int' and 'str'

我几乎可以肯定的代码是正确的，但txt文件是混乱的一切。我在下面包括了回溯。你知道吗

非常简单，您读入一堆字符数据，而从不转换为整数。然后尝试对数据执行算术运算，从整数值0开始。你知道吗

在某个时刻，你必须转换你的值。目前，您有一个126x1“2Dim列表”。对行求和的尝试从尝试添加0 + "4"开始。你知道吗

我强烈建议您恢复到增量编程。您发布了100行代码，但没有测试为程序其余部分提供信息的输入。你知道吗
