大家好, 目前正在自學python,下面的範例1很好理解
但範例2的結果誰能幫忙解釋一下為何結果不是我所想的
{ 0+0*0 , 1+1*1 , 2+2*2.....9+9*9........} = {0, 2, 6, 12, 20, 30, 42, 56, 72.....90}
EX.1
testDic = {i: i * i for i in range(10)}
print(testDic)
ANS: {0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81}
EX.2
testDxc = {i+ i * i for i in range(10)}
print(testDxc)
ANS: {0, 2, 6, 72, 42, 12, 20, 56, 90, 30}
謝謝 |
