Answer : Assuming you're on at least 3.2, there's a built in for this: int.from_bytes ( bytes, byteorder, *, signed=False ) ... The argument bytes must either be a bytes-like object or an iterable producing bytes. The byteorder argument determines the byte order used to represent the integer. If byteorder is "big", the most significant byte is at the beginning of the byte array. If byteorder is "little", the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. The signed argument indicates whether two’s complement is used to represent the integer. ## Examples: int.from_bytes(b'\x00\x01', "big") # 1 int.from_bytes(b'\x00\x01', "little") # 256 int.from_bytes(b'\x00\x10', byteorder='little') # 4096 int.from_bytes(b'\xfc...

Answer : For (at least) Python 3.7 According to the docs: bytes objects are immutable sequences of single bytes bytearray objects are a mutable counterpart to bytes objects. And that's pretty much it as far as bytes vs bytearray . In fact, they're fairly interchangeable and designed to flexible enough to be mixed in operations without throwing errors. In fact, there is a whole section in the official documentation dedicated to showing the similarities between the bytes and bytearray apis. Some clues as to why from the docs: Since many major binary protocols are based on the ASCII text encoding, bytes objects offer several methods that are only valid when working with ASCII compatible data and are closely related to string objects in a variety of other ways. In Python 2.6 bytes is merely an alias for str . This "pseudo type" was introduced to [partially] prepare programs [and programmers!] to be converted/compatible with Python 3.0 where there is a ...

Answer : From this: (source) function bytesToSize(bytes) { var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB']; if (bytes == 0) return '0 Byte'; var i = parseInt(Math.floor(Math.log(bytes) / Math.log(1024))); return Math.round(bytes / Math.pow(1024, i), 2) + ' ' + sizes[i]; } Note : This is original code, Please use fixed version below. Aliceljm does not active her copied code anymore Now, Fixed version unminified, and ES6'ed: (by community) function formatBytes(bytes, decimals = 2) { if (bytes === 0) return '0 Bytes'; const k = 1024; const dm = decimals < 0 ? 0 : decimals; const sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB']; const i = Math.floor(Math.log(bytes) / Math.log(k)); return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i]; } Now, Fixed version : (by Stac...
