Using ASTKit

Rendering

ASTKit provides a source code renderer astkit.render.SourceCodeRenderer that will transform an ast.Node tree into syntactically correct Python source code. This is easy to do. Have a look at the following example:

>>> import ast
>>> call = ast.Call(func=ast.Attribute(value=ast.Name(id='somemodule'),
...                                    attr='somefunc'),
...                 args=[ast.Num(n=8),
...                       ast.Num(n=15),
...                       ],
...                 keywords=[])
>>> from astkit.render import SourceCodeRenderer
>>> SourceCodeRenderer.render(call)
'somemodule.somefunc(8, 15)'

In the example, you can see that we create an ast.Call node; this node represents a function call. Specifically, it is a call to the function ‘somefunc’ from the module ‘somemodule’ with two arguments: 8 and 15. You can see that when we call SourceCodeRenderer.render on it we get ‘somemodule.somefunc(8, 15)’, which is just what we would expect.
