我的程序应该检查矩阵是否是魔方。但它跳过“添加对角线”并检查表中是否所有数字(1-16)。
ROWS=4
COLUMNS=4
def main():
tbl=[]
numChecktbl=[]
for i in range (ROWS):
tbl.append([])
for j in range (COLUMNS):
userinput=int(input("Enter a value for location (%d,%d): " %(i,j)))
tbl[i].append(userinput)
numChecktbl.append(userinput)
for i in range(ROWS):
for j in range(COLUMNS):
print("%3d" %tbl[i][j], end='')
print()
if (totSumRowsColumns(ROWS,COLUMNS,tbl)and totSumDiagonals(ROWS,COLUMNS,tbl)
and numInMatrix(numChecktbl)):
print("It is a magic square")
else:
print("It is not a magic square")
def totSumRowsColumns(ROWS,COLUMNS,tbl):
for i in range (ROWS):
totalrow=0
totalColumn=0
for j in range (COLUMNS):
totalColumn+=tbl[j][i]
totalrow=totalrow+tbl[i][j]
if (totalrow != 34!=totalColumn):
return False
return True
def totSumDiagonals(ROWS,COLUMNS,tbl):
totDiag1=0
totDiag2=0
for i in range (ROWS):
for j in range (COLUMNS):
totDiag1=tbl[0][3]+tbl[1][2]+tbl[2][1]+tbl[3][0]
if i==j:
totDiag2+=tbl[i][j]
if (totDiag1!=totDiag2!=34):
return False
return True
def numInMatrix(numChecktbl):
for i in range(1,17):
if i not in numChecktbl:
return False
return True
main()
答案 0 :(得分:0)
由于你的if语句包含多个需要全部为真的条件,所以只要一个为假,它就会移到else上。
当您的输入有效时,将运行所有功能和检查。但是,当您的输入不是幻方时,totSumRowsColumns
将返回false并停止检查。
