我们从Python开源项目中，提取了以下15个代码示例，用于说明如何使用symbol.file_input()。
def compile_node(self, node): ### emit a line-number node? n = node[0] if n == symbol.encoding_decl: self.encoding = node[2] node = node[1] n = node[0] if n == symbol.single_input: return self.single_input(node[1:]) if n == symbol.file_input: return self.file_input(node[1:]) if n == symbol.eval_input: return self.eval_input(node[1:]) if n == symbol.lambdef: return self.lambdef(node[1:]) if n == symbol.funcdef: return self.funcdef(node[1:]) if n == symbol.classdef: return self.classdef(node[1:]) raise WalkerError, ('unexpected node type', n)
def file_input(self, nodelist): doc = self.get_docstring(nodelist, symbol.file_input) if doc is not None: i = 1 else: i = 0 stmts = [] for node in nodelist[i:]: if node[0] != token.ENDMARKER and node[0] != token.NEWLINE: self.com_append_stmt(stmts, node) return Module(doc, Stmt(stmts))
def get_docstring(self, node, n=None): if n is None: n = node[0] node = node[1:] if n == symbol.suite: if len(node) == 1: return self.get_docstring(node[0]) for sub in node: if sub[0] == symbol.stmt: return self.get_docstring(sub) return None if n == symbol.file_input: for sub in node: if sub[0] == symbol.stmt: return self.get_docstring(sub) return None if n == symbol.atom: if node[0][0] == token.STRING: s = '' for t in node: s = s + eval(t[1]) return s return None if n == symbol.stmt or n == symbol.simple_stmt \ or n == symbol.small_stmt: return self.get_docstring(node[0]) if n in _doc_nodes and len(node) == 1: return self.get_docstring(node[0]) return None
