class bz2.BZ2Decompressor Create a new decompressor object. This object may be used to decompress data incrementally. For one-shot compression, use the decompress() function instead. Note This class does not transparently handle inputs containing multiple compressed streams, unlike decompress() and BZ2File. If you need to decompress a multi-stream input with BZ2Decompressor, you must use a new decompressor for each stream. decompress(data, max_length=-1) Decompress data (a bytes-like ob

flush() Finish the compression process. Returns the compressed data left in internal buffers. The compressor object may not be used after this method has been called.

compress(data) Provide data to the compressor object. Returns a chunk of compressed data if possible, or an empty byte string otherwise. When you have finished providing data to the compressor, call the flush() method to finish the compression process.

class bz2.BZ2Compressor(compresslevel=9) Create a new compressor object. This object may be used to compress data incrementally. For one-shot compression, use the compress() function instead. compresslevel, if given, must be a number between 1 and 9. The default is 9. compress(data) Provide data to the compressor object. Returns a chunk of compressed data if possible, or an empty byte string otherwise. When you have finished providing data to the compressor, call the flush() method to fin

exception BytesWarning Base class for warnings related to bytes and bytearray.

bytes.zfill(width) bytearray.zfill(width) Return a copy of the sequence left filled with ASCII b'0' digits to make a sequence of length width. A leading sign prefix (b'+'/ b'-' is handled by inserting the padding after the sign character rather than before. For bytes objects, the original sequence is returned if width is less than or equal to len(seq). For example: >>> b"42".zfill(5) b'00042' >>> b"-42".zfill(5) b'-0042' Note The bytearray version of this method does not o

bytes.upper() bytearray.upper() Return a copy of the sequence with all the lowercase ASCII characters converted to their corresponding uppercase counterpart. For example: >>> b'Hello World'.upper() b'HELLO WORLD' Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. Note The bytearray version of this method does not operate in place - it always p

bytes.translate(table[, delete]) bytearray.translate(table[, delete]) Return a copy of the bytes or bytearray object where all bytes occurring in the optional argument delete are removed, and the remaining bytes have been mapped through the given translation table, which must be a bytes object of length 256. You can use the bytes.maketrans() method to create a translation table. Set the table argument to None for translations that only delete characters: >>> b'read this short text'.t

bytes.title() bytearray.title() Return a titlecased version of the binary sequence where words start with an uppercase ASCII character and the remaining characters are lowercase. Uncased byte values are left unmodified. For example: >>> b'Hello world'.title() b'Hello World' Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. All other byte value

bytes.swapcase() bytearray.swapcase() Return a copy of the sequence with all the lowercase ASCII characters converted to their corresponding uppercase counterpart and vice-versa. For example: >>> b'Hello World'.swapcase() b'hELLO wORLD' Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. Unlike str.swapcase(), it is always the case that bin.swap
