逐行读取原始二进制文件，将其转换为ascii并以相同的方式以.txt格式存储

Question

I am able to read raw binary data line by line but can't store it line by line into a .txt file. Can someone please help me.

Here is my code:

with open("aa.dwr", "rb") as file:
  data = file.readline()
  datastring = str(data)
  while data:
    with open("out1.txt", "w") as f:
      f.write(' '.join(map(str,data)))
      f.write("\r\n")
    print("line {}: {}".format(cnt, map(str,datastring.strip())))
    data = file.readline()
    cnt +=1

Answer 1

with open("out1.txt", "w") as f:
    while data:
        f.write(' '.join(map(str,data)))
        f.write("\r\n")
        print("line {}: {}".format(cnt, map(str,datastring.strip())))
        data = file.readline()
        cnt +=1

Please try like this...

or you can try like

while data:
    with open("out1.txt", "a") as f:
        f.write(' '.join(map(str,data)))
        f.write("\r\n")
    print("line {}: {}".format(cnt, map(str,datastring.strip())))
    data = file.readline()
    cnt +=1

If your original data is string encoded as binary then you can read the binary and then decode it to string. Then split the string line-by-line and write it to file.
This only applies if you want to split the text as string line-by-line. If you want to split binary line-by-line, like @Selcuk mentioned, what does that even mean?

with open("file.b", "rb") as f:
     data = f.read()
     data = data.decode()
     lines = data.splitlines()

     with open("out.txt", "w") as f2:
         for line in lines:
             f2.write(line + "\n")
