Always use a (like HxD or the VS Code Hex Editor extension) when debugging. Seeing the actual hexadecimal values 48 45 58 is much more helpful than seeing scrambled text symbols in a standard editor. binarni_soubory_1.zip

struct.pack('i', 42) : Turns the integer 42 into a 4-byte sequence. : Storing database-style entries without separators
When you open a file with the b flag (like rb or wb ), you aren't reading strings—you're reading . 1. The "Bytes" Object
The files inside binarni_soubory_1.zip demonstrate three core concepts: 🛠️ Essential Operations Always use a (like HxD
In Python, binary data is handled via the bytes type. These are immutable sequences of integers between 0 and 255. : f.read(4) gets exactly four bytes. Write : f.write(b'\x01\x02\x03') writes specific hex values. 2. Structuring Data with struct
