Some of data may be buffered internally, for use in later calls to decompress (). decompress (z) >>> y b'some string to test zlib . Since Python strings are immutable, we’ll need to work off of a list of characters, and at the end convert that list back into a string with a join statement. Approach is very simple, first we create a ordered dictionary which contains characters of input string as key and 0 as their default value, now we run a loop to count frequency of each character and will map it to it’s corresponding key. decompress() # extra data does not matter so we just read the most we can. decompress(gz_data, 16+zlib. close () ifile = bz2.
