Python - ast - How to find first function -


i'm trying find first function in arbitrary python code.

what's best way this?

here's i've tried far. 

import ast import compiler.ast  code = """\ def func1():     return 1  def func2():     return 2  """  tree = compiler.parse(code)  print list(ast.walk(tree))

but i'm getting error don't understand.

traceback (most recent call last):   file "test.py", line 15, in <module>     print list(ast.walk(tree))   file "/usr/lib64/python2.7/ast.py", line 215, in walk     todo.extend(iter_child_nodes(node))   file "/usr/lib64/python2.7/ast.py", line 180, in iter_child_nodes     name, field in iter_fields(node):   file "/usr/lib64/python2.7/ast.py", line 168, in iter_fields     field in node._fields: attributeerror: module instance has no attribute '_fields'

use ast.parse, not compiler.parse:

>>> import ast >>>  >>> code = """ ... def func1(): ...     return 1 ...  ... def func2(): ...     return 2 ... """ >>>  >>> tree = ast.parse(code) >>> [x.name x in ast.walk(tree) if isinstance(x, ast.functiondef)] ['func1', 'func2']

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
