我们从Python开源项目中，提取了以下10个代码示例，用于说明如何使用symbol.testlist_comp()。
def testlist_comp(self, nodelist): # test ( comp_for | (',' test)* [','] ) assert nodelist[0][0] == symbol.test if len(nodelist) == 2 and nodelist[1][0] == symbol.comp_for: test = self.com_node(nodelist[0]) return self.com_generator_expression(test, nodelist[1]) return self.testlist(nodelist)
def com_assign(self, node, assigning): # return a node suitable for use as an "lvalue" # loop to avoid trivial recursion while 1: t = node[0] if t in (symbol.exprlist, symbol.testlist, symbol.testlist_safe, symbol.testlist_comp): if len(node) > 2: return self.com_assign_tuple(node, assigning) node = node[1] elif t in _assign_types: if len(node) > 2: raise SyntaxError, "can't assign to operator" node = node[1] elif t == symbol.power: if node[1][0] != symbol.atom: raise SyntaxError, "can't assign to operator" if len(node) > 2: primary = self.com_node(node[1]) for i in range(2, len(node)-1): ch = node[i] if ch[0] == token.DOUBLESTAR: raise SyntaxError, "can't assign to operator" primary = self.com_apply_trailer(primary, ch) return self.com_assign_trailer(primary, node[-1], assigning) node = node[1] elif t == symbol.atom: t = node[1][0] if t == token.LPAR: node = node[2] if node[0] == token.RPAR: raise SyntaxError, "can't assign to ()" elif t == token.LSQB: node = node[2] if node[0] == token.RSQB: raise SyntaxError, "can't assign to []" return self.com_assign_list(node, assigning) elif t == token.NAME: return self.com_assign_name(node[1], assigning) else: raise SyntaxError, "can't assign to literal" else: raise SyntaxError, "bad assignment (%s)" % t
