Every value in Python has a datatype. save dictionary to a pickle file (. Python String is immutable, so we can't change its value. The slides are an excellent overview of the design of Python 2’s Unicode features (where the Unicode string type is called unicode and literals start with u). Tuples are also comparable and hashable so we can sort lists of them and use tuples as key values in Python. Support for Python 2 will be discontinued on or after December 31, 2020—one year after the Python 2 sunsetting date. Let's see how JSON's main website defines it: Thus, JSON is a simple way to create and store data structures within JavaScript. It could be the case that you want to convert the unicode to ASCII or to some other encoding. Dictionary in Python is an unordered collection of data values, used to store data values like a map, which unlike other Data Types that hold only single value as an element, Dictionary holds key:value pair. Since they are immutable, they are also hashable, which means that frozensets can be used as members in other sets and as dictionary keys. AttributeError: unicode object has no attribute 'append'. Additionally, you can follow the installation instructions on the page if you need more help to get everything installed properly. #!/usr/bin/python print u'Hello, world!'
