我正在尝试解析 BMP 文件，进行一些更改，然后使用 Python 重新组装新的 BMP。
回车似乎是个大问题。当我使用 Notepad++ 打开位图文件并搜索 "\r' 时，该字符不存在。我在 Python 中读取该文件 (readData = fileIn.read()) 并尝试使用 "\n" 效果很好。
>readData.find('\r') 它返回 -1。目前 尝试将完全相同的文本块写入新的使用 fileOut.write(readData) 的 BMP 并使用 Notepad++ 搜索 "\r"，我能够找到它（两次，每次对应于预先存在的 "\n" 字符）。
有没有办法在不自动添加 "\r" 的情况下将此数据块写入新的 BMP？ .strip() 和在将字符串写入新文件之前将 .replace('\r','') 替换为该字符串。
I'm trying to parse a BMP file, do some changes and then reassemble a new BMP using Python.
The carriage return seems to be a huge problem. When I open the bitmap file using Notepad++ and search for "\r', the character does not exist. I read the file in Python (readData = fileIn.read()) and try searching using readData.find('\r') it returns -1. Searching for "\n" works fine. All is good for now.
When I try to write this exact same block of text into a new BMP using fileOut.write(readData) and I use Notepad++ to search for "\r", I am able to find it (twice, each corresponding to the preexisting "\n" characters).
Is there a way to write this block of data to a new BMP without "\r" being added automatically? I've tried applying .strip() and .replace('\r','') to the string before writing it to the new file.

当您想以二进制方式打开文件时，您可能会以文本方式打开文件（默认）。
来自文档：
You're probably opening the file as text (the default) when you want to open it as binary.
From the documentation:
您正在以文本模式打开文件，而您需要二进制模式。在这里找到有关 open() 的更多信息：
http://docs.python.org/library/functions.html
You are opening the file in text mode, while you need binary mode. Find more about open() here:
