在 Python 2 中,您需要神奇的编译器包:
>>> import compiler
>>> mod = compiler.parseFile("doublelib.py")
>>> mod
Module('This is an example module.\n\nThis is the docstring.\n',
Stmt([Function(None, 'double', ['x'], [], 0,
'Return twice the argument',
Stmt([Return(Mul((Name('x'), Const(2))))]))]))
>>> from compiler.ast import *
>>> Module('This is an example module.\n\nThis is the docstring.\n',
... Stmt([Function(None, 'double', ['x'], [], 0,
... 'Return twice the argument',
... Stmt([Return(Mul((Name('x'), Const(2))))]))]))
Module('This is an example module.\n\nThis is the docstring.\n',
Stmt([Function(None, 'double', ['x'], [], 0,
'Return twice the argument',
Stmt([Return(Mul((Name('x'), Const(2))))]))]))
>>> mod.doc
'This is an example module.\n\nThis is the docstring.\n'
>>> for node in mod.node.nodes:
... print node
...
Function(None, 'double', ['x'], [], 0, 'Return twice the argument',
Stmt([Return(Mul((Name('x'), Const(2))))]))
>>> func = mod.node.nodes[0]
>>> func.code
Stmt([Return(Mul((Name('x'), Const(2))))])
在 Python 3 中,它直接内置在.
