: Identifying a file type by its first few "magic" bytes.
The struct module is the "translator" between Python variables and binary formats.
Working with binary files in Python (or C++) often feels like a dark art compared to the simplicity of text files. This post breaks down the basics of handling raw data using the binarni_soubory_1.zip example set. 💾 Why Binary? Text files are for humans; binary files are for machines. : No overhead from encoding/decoding.
: Why the order of bytes matters (Big-endian vs. Little-endian). 💡 Pro Tip
struct.pack('i', 42) : Turns the integer 42 into a 4-byte sequence.
