Description: # IPyWalrus
        
        IPyWalrus is a simple IPython (Jupyter) extension which enables you to use the walrus
        operator ([PEP 572 - Assignment Expressions](https://www.python.org/dev/peps/pep-0572/)) `:=`
        for usual assignments in IPython or Jupyter.
        
        This part of the PEP:
        
        ```
        There are a few places where assignment expressions are not allowed, in order to avoid ambiguities or user confusion:
        
        Unparenthesized assignment expressions are prohibited at the top level of an expression statement. Example:
        
        y := f(x)  # INVALID
        (y := f(x))  # Valid, though not recommended
        
        This rule is included to simplify the choice for the user between an assignment statement and an assignment expression -- there is no syntactic position where both are valid.
        
        ```
        
        is completely valid but my IPython sessions of Jupyter notebooks are full of cells like this one:
        
        ![standard](images/standard.png)
        
        and because it does not work in pure Python
        
        ![error](images/error.png)
        
        I've prepared a small extension which makes it work:
        
        ![ipywalrus](images/ipywalrus.png)
        
        ## Usage
        
        Install the extension from pip or download the ipywalrus.py and put it somewhere in `PYTHONPATH`:
        
        ```
        # pip install ipywalrus
        ```
        
        and load it in IPython or Jupyter
        
        ```
        %load_ext ipywalrus
        ```
        
        If you want to enable this extension permamently, create a default profile (if you don't have one already) `ipython profile create` and then add ipywalrus to the list of extensions in `~/.ipython/profile_default/ipython_config.py`.
