Simple file archiver in Python Part 2:Archiving

Today, I would like to explain how to create a function that archives files.

Now, I have to add signatures and data(file name and content) to my buffer(arc_buf). Also, I have to do that for each file.

def archive(file_list):   
    for element in file_list:
        for bt in new_file_bytes:
            arc_buf.append(bt)
        for bt in file_name_bytes:
            arc_buf.append(bt)
        for bt in element:
            arc_buf.append(ord(bt))
        for bt in file_content_bytes:
            arc_buf.append(bt)
        

To read binary data from files, I can use “with open(element,”rb”) as f:”.

        with open(element,"rb") as f:
            f_buf = f.read()
            for bt in f_buf:
                arc_buf.append(bt)   

So, I want to save my buffer to a file. To do that I can also use open() function but now with mode “wb”.

    with open(file_list[0] + ".ca","wb") as f:
        f.write(arc_buf)
    print("DONE")

open() function modes:

“w” – write text to a file

“r” – read text from a file

“wb” – write binary data to a file

“rb” – read binary from a file
