Python Character coding Exercises

Deepen your understanding of Python character encoding with the following exercises

#\x00-\xff 256 character (S )>>>A = range (256)
>>>b = Bytes (a)#No parameter encoding>>>bB ' \x00\x01\x02 ... \xf6\xf7\xf8\xf9\xfa\xfb\xfc\xfd\xfe\xff '>>>B.decode ('Utf-8')#Error Traceback (most recent): File "<stdin>", line 1, in <module>unicodedecodeerror: ' Utf-8 ' codec can ' t decode byte 0x80 in position 128:invalid start byt E>>>B.decode ('Unicode-escape')#Normal' \x00\x01\x02 ... \xf6÷\xf8ùú\xfbü\xfd\xfe\xff '

# out of the question: the above sentence is equivalent to the following sentence
>>> ". Join (List (map (CHR, range (256)))
