The open() function opens a file in text format by default. To open a file in binary format, add ‘b’ to the mode parameter. Hence the “rb” mode opens the file in binary format for reading, while the “wb” mode opens the file in binary format for writing. Unlike text files, binary files are not human-readable.
- file = open(“sample.bin”, “rb”)
- byte = file. read(1)
- while byte: byte=false at end of file.
- print(byte)
- byte = file. read(1)
- file. close()
- Use the ReadAllBytes method, which returns the contents of a file as a byte array. This example reads from the file C:/Documents and Settings/selfportrait. …
- For large binary files, you can use the Read method of the FileStream object to read from the file only a specified amount at a time.
- Line [1] assigns the size of the chunk to the variable chunk_size .
- Line [2] assigns the variable image_file to the file to be read in.
- Line [3] opens the image_file .
- Line [4] instantiates the while loop and executes while True . Line [5] reads in a chunk of the open file for each loop.
