请教各位，'float' object is not subscriptable?400报错

请教各位大侠，问题如下

list_001 = [9.1454247, 53.48538079999999, 9.01548, 53.16778, 9.1434819, 53.4873555, 9.1451686, 53.48564990000001, 9.14256, 53.48726, 9.1393, 53.48882, 9.145203, 53.4865261, 9.1449977, 53.4899644, 9.1448787, 53.4857361, 9.14495, 53.48965, 9.145296799999999, 53.485342, 9.1447931, 53.4865513, 9.1454247, 53.48538079999999]

for num1 in range(1, len(list_001)):
  k1 = list_001[num1][0]
  k2 = list_001[num1][1]
  print(num1)
  print(k1)
  print(k2)

运行结果报错是

  File "C:\Python_3.6\Python_File_Py\EX_001\range_print.py", line 4, in <module>
    k1 = list_001[num1][0]
TypeError: 'float' object is not subscriptable

请教大家应该怎么改正啊
