Invalid syntax for turtle name (python) -


i trying write program draw flower, no matter keeps throwing "invalid syntax" error turtle name. have taken out of other code, tried naming turtle different, yet nothing works. ideas? 

import turtle  def draw_flower():     window = turtle.screen()     window.bgcolor(#42dff4)      sam = turtle.turtle()     sam.forward(50)  window.exitonclick()  draw_flower()

besides quoting color string, noted in comments, lines of code in wrong order. example, nothing should follow window.exitonclick():

window.exitonclick()  draw_flower()

make (or window.mainloop()) last statement of program that's when code ends , tk event handler loop begins. i.e. reverse order of these 2 statements. second problem variable window in wrong scope:

def draw_flower():     window = turtle.screen()     ...  window.exitonclick()

since it's defined locally in draw_flower(), it's not available use globally. here's rework of code addressing both issues:

import turtle  def draw_flower():     sam = turtle.turtle()     sam.forward(50)  window = turtle.screen() window.bgcolor("#42dff4")  draw_flower()  window.exitonclick()

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
