ValueError:在拆分整数和小数时，没有足够的值进行解包（应为2，得到1）

Question

我试图把一个浮点数转换成它的二进制表示形式。我不明白为什么当我试图将整数和小数部分分开时，会出现这个错误

ValueError: not enough values to unpack (expected 2, got 1)

这是密码

import decimal
from ctypes import *
def float_bin(number, places = 32): 
    **whole, dec = str(number).split(".")** 
    whole = int(float(whole)) 
    dec = int (float(dec)) 

    res = bin(whole).lstrip("0b") + "."

    for x in range(places): 
        whole, dec = str((decimal_converter(dec)) * 2).split(".") ////error here
        dec = int(dec) 
        res += whole 
    return res 

def decimal_converter(num):  
    while num > 1: 
        num /= 10
    return num 


a = float(float_bin(0.0000567))   
print ('%32.f', a)
number = cast(pointer(c_float(a)), POINTER(c_int32)).contents.value
bitpos = 0
while number != 0:
  bitpos = bitpos + 1             # increment the bit position
  number = number >> 1 # shift the whole thing to the right once
  if(number >= 1) :
     break

  print ('%3.f', bitpos)

您在第6行将“dec”定义为一个整数，然后在decimal\u converter中对其执行整数（floor）除法，它还返回一个整数，该整数没有小数点可拆分。你知道吗
