bytearray.isspace() Return true if all bytes in the sequence are ASCII whitespace and the sequence is not empty, false otherwise. ASCII whitespace characters are those byte values in the sequence b' \t\n\r\x0b\f' (space, tab, newline, carriage return, vertical tab, form feed).

bytearray.isdigit() Return true if all bytes in the sequence are ASCII decimal digits and the sequence is not empty, false otherwise. ASCII decimal digits are those byte values in the sequence b'0123456789'. For example: >>> b'1234'.isdigit() True >>> b'1.23'.isdigit() False

bytearray.isalpha() Return true if all bytes in the sequence are alphabetic ASCII characters and the sequence is not empty, false otherwise. Alphabetic ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'. For example: >>> b'ABCabc'.isalpha() True >>> b'ABCabc1'.isalpha() False

bytearray.isalnum() Return true if all bytes in the sequence are alphabetical ASCII characters or ASCII decimal digits and the sequence is not empty, false otherwise. Alphabetic ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'. ASCII decimal digits are those byte values in the sequence b'0123456789'. For example: >>> b'ABCabc1'.isalnum() True >>> b'ABC abc1'.isalnum() False

bytearray.hex() Return a string object containing two hexadecimal digits for each byte in the instance. >>> bytearray(b'\xf0\xf1\xf2').hex() 'f0f1f2' New in version 3.5.

bytearray.index(sub[, start[, end]]) Like find(), but raise ValueError when the subsequence is not found. The subsequence to search for may be any bytes-like object or an integer in the range 0 to 255. Changed in version 3.3: Also accept an integer in the range 0 to 255 as the subsequence.

bytearray.find(sub[, start[, end]]) Return the lowest index in the data where the subsequence sub is found, such that sub is contained in the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found. The subsequence to search for may be any bytes-like object or an integer in the range 0 to 255. Note The find() method should be used only if you need to know the position of sub. To check if sub is a substring or not, use the in o

classmethod bytearray.fromhex(string) This bytearray class method returns bytearray object, decoding the given string object. The string must contain two hexadecimal digits per byte, with ASCII spaces being ignored. >>> bytearray.fromhex('2Ef0 F1f2 ') bytearray(b'.\xf0\xf1\xf2')

bytearray.expandtabs(tabsize=8) Return a copy of the sequence where all ASCII tab characters are replaced by one or more ASCII spaces, depending on the current column and the given tab size. Tab positions occur every tabsize bytes (default is 8, giving tab positions at columns 0, 8, 16 and so on). To expand the sequence, the current column is set to zero and the sequence is examined byte by byte. If the byte is an ASCII tab character (b'\t'), one or more space characters are inserted in the

bytearray.decode(encoding="utf-8", errors="strict") Return a string decoded from the given bytes. Default encoding is 'utf-8'. errors may be given to set a different error handling scheme. The default for errors is 'strict', meaning that encoding errors raise a UnicodeError. Other possible values are 'ignore', 'replace' and any other name registered via codecs.register_error(), see section Error Handlers. For a list of possible encodings, see section Standard Encodings. Note Passing the enc
