This means that before Python3 we could treat a set of bytes as a string and work from there, this is not the case now, now we have a separate data type, called bytes. This data type can be briefly explained as a string of bytes, which essentially means, once the bytes data type is initialized it is immutable. This presents another problem, we need to know the encoding of a binary string, because the same string in another encoding latin-1 looks different.

As seen above it is possible to encode or decode strings and binary strings using the encode or decode function. We need the encoding because in some encodings it is not possible to to decode the strings. This problem compounds when not using non Latin characters like Hebrew, Japanese and Chinese. Because in those languages more than one byte is assigned to each letter. But what do we use when we need to modify a set of bytes, we use a bytearray. In Python, bitwise operators are used to perform bitwise calculations on integers.

The integers are first converted into binary and then operations are performed on bit by bit, hence the name bitwise operators. The standard bitwise operations are demonstrated below. Note: For more information, refer to Python Bitwise Operators. Binary data provides several applications like we can check if the two files are similar or not using the binary data, we can also check for a whether a file is jpeg or not or any other image format.

Note: These are not character encodings, those come later. This clearly shows a string of bits can be interpreted differently in different ways. We often use the hex representation of a byte instead of the binary one because it is shorter to write, this is just a representation and not an interpretation. Now that we know what a byte is and what it looks like, let us see how it is interpreted, mainly in strings.

Character Encodings are a way to assign values to bytes or sets of bytes that represent a certain character in that scheme. Some encodings are ASCII probably the oldest , Latin, and UTF-8 most widely used as of today. In a sense encodings are a way for computers to represent, send and interpret human readable characters.

This means that a sentence in one encoding might become completely incomprehensible in another encoding. In Python 2, the str type was used for two different kinds of values — text and bytes, whereas in Python 3, these are separate and incompatible types. This means that before Python3 we could treat a set of bytes as a string and work from there, this is not the case now, now we have a separate data type, called bytes. This data type can be briefly explained as a string of bytes, which essentially means, once the bytes data type is initialized it is immutable.

To request the native byte order of the host system, use sys. If omitted or None , the chars argument defaults to removing whitespace. Module attributes can be assigned to. This generates a string similar to that returned by repr in Python 2. Otherwise, any valid keys can be used. dirpath , dirnames and filenames are identical to walk output, and dirfd is a file descriptor referring to the directory dirpath.
