How to open a binary file in read and write mode with Python?
To open binary files in binary read/write mode, specify 'w+b' as the mode(w=write, b=binary). For example,
f = open('my_file.mp3', 'w+b') file_content = f.read() f.write(b'Hello') f.close()
Above code opens my_file.mp3 in binary read/write mode, stores the file content in file_content variable and rewrites the file to contain "Hello" in binary. You can also use r+mode as it doesn't truncate the file.
