如何修复并非所有在字符串格式化期间转换的参数？

Question

I want to change some binary streams to decimal but I got not all arguments converted during string formatting . The point is I have the result when using binaryToDecimal (10100000) which 10100000 is the first value of my list. But when I use binaryToDecimal (instream_chunks[0]) which is my for loop I got the above error. How can I fix that? I am new to python sorry for my simple question.......

def binaryToDecimal(binary):
      
    binary1 = binary
    decimal, i, n = 0, 0, 0
    while(binary != 0):
        dec = binary % 10
        decimal = decimal + dec * pow(2, i)
        binary = binary//10
        i += 1
    print(decimal)
    
    instream = '1010000000011000000110000000001'

    instream_chunks = [instream[i:i+8]for i in range (0, len(instream), 8)]

for i in range (len(instream_chunks)):
    
     img_value = binaryToDecimal (instream_chunks[i])

You need to convert the strings to integers before using your function on them. Like so:

def binaryToDecimal(binary):
      
    binary1 = binary
    decimal, i, n = 0, 0, 0
    while(binary != 0):
        dec = binary % 10
        decimal = decimal + dec * pow(2, i)
        binary = binary//10
        i += 1
    print(decimal)
    
instream = '1010000000011000000110000000001'

instream_chunks = [instream[i:i+8]for i in range (0, len(instream), 8)]

for i in range (len(instream_chunks)):
     img_value = binaryToDecimal (int(instream_chunks[i]))
