To include the base64 module in your script, you must import it first: import base64 The base64 encode and decode functions both require a bytes-like object. 9 is released, codepage may be changed by how Python is started, or how Python is installed. encoding − This is the encodings to be used. There are other ways to implement one-hot encoding in python such as with Pandas data frames. You will learn more about various encoding techniques in machine learning for categorical data in Python. You may be asked to decode data in a coding job. Unicode string is designed to store text data. They should generally be applied to Unicode text that will later be encoded appropriately, or to already-encoded text using an ASCII-superset encoding, since most characters are left alone. You're perhaps trying to decode a string which was not encoded in the utf8 encoding. In python, text could be presented using unicode string or bytes.

In general, it is more compelling to use unicode_literals when back-porting new or existing Python 3 code to Python 2/3 than when porting existing Python 2 code to 2/3. maxunicode > 0xffff True See PEP 261 for details regarding support for “wide” Unicode characters in Python. Huffman encoding is a way to assign binary codes to symbols that reduces the overall number of bits used to encode a typical string of of those symbols. It is generally not needed, and it causes things to break like this by making one Python load things from another Python (in this case, it looks like the system's Python 3 is trying to load something that was written for Python 2).
