Welcome to astroid's documentation!
===================================
**astroid** is a library for AST parsing, static analysis and inference,
currently powering most of **pylint** capabilities.
It offers support for parsing Python source code into ASTs, similar to how
the builtin **ast** module works. On top of that, it can partially infer various
Python constructs, as seen in the following example::
from astroid import parse
module = parse('''
def func(first, second):
return first + second
arg_1 = 2
arg_2 = 3
func(arg_1, arg_2)
''')
>>> module.body[-1]
<Expr l.3 at 0x10ab46f28>
>>> inferred = next(module.body[-1].value.infer())
>>> inferred
<Const.int l.None at 0x10ab00588>
>>> inferred.value
5
**astroid** also allows the user to write various inference transforms for
enhancing its Python understanding, helping as well **pylint** in the process
of figuring out the dynamic nature of Python.
