python - 我正在尝试为我的格式化答案命名，但它不起作用

Question

 for x in range(1.11):
    print ('Number: {0:2d} Square: {1:3d} Cube: {2:4d}'.format(x, x*x, x*x*x))

Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
    for x in range(1.11):
TypeError: 'float' object cannot be interpreted as an integer

Answer 1

您使用 a.而不是 a ,infor x in range(1.11):它应该是：

for x in range(1,11):
    print ('Number: {0:2d} Square: {1:3d} Cube: {2:4d}'.format(x, x*x, x*x*x))
