Question

python code
We're using structs and focusing on binary file I/O

def read_attributes(file_path, format):
    """
    Given a binary file written using struct.pack() with the given format, return the number of bytes in the file and the number of bytes in each chunk.

    :param file_path:
    :param format: a string with the format of the data in the struct
    :return: tuple with the number of bytes in file and the number of bytes written in each chunk
    """

Answer 1

Here is the solution to above problem. The chunk size is taken up to be 1024 Bytes or 1KB . In the above problem we need to open the file as a binary file and read 1024 bytes at a time.

Python code

def read_attributes(file_path, Format):
Chunk=0 #number of chunks
Bytes=0
with open(fileName, Format) as fin:
bytesRead = fin.read(1024) #1024 is the chunk size
Chunk=Chunk+1
for byte in bytesRead:
Bytes=Bytes+1;
return (Bytes,Chunk)

fileName = raw_input("Enter a file name:")
read_attributes(fileName,"rb")
