WebThe syntax for creating a byte array in Python is as follows: my_bytes = bytes ( [0, 1, 2, 3, 4, 5, 6, 7]) This creates a byte array with eight bytes, each containing the corresponding integer value. Alternatively, we can use the bytearray () constructor to create a mutable byte array as follows: my_bytearray = bytearray ( [0, 1, 2, 3, 4, 5, 6, 7]) WebOne such module is the struct module. The struct module has three methods: pack (), unpack (), and calcsize (). The pack method accepts two parameters: format and data to be converted to bytes. Like the struct blueprint in C, the format part of the pack function in Python accepts various data types. For example, struct.pack('iif', 2, 4, 7.68)
