Hi when I tried to use this piece of code:
import media
toy_story = media.Movie("Toy Story","A story of a boy and his toys come to life","http://upload.wikimedia.org/wikipedia/en/1/13/Toy_Story.jpg","https://www,youtube.com/watch?v=vwyZH85NQC4")
print(toy_story.storyline)
The directory for media and this file is: C:\Users\Lukes\Desktop\media
The code for media is here:
class Movie():
def __init__(self, movie_title, movie_storyline, poster_image, trailer_youtube):
self.title = movie_title
self.storyline = movie_storyline
self.poster_image_url = poster_image
self.trailer_youtube_url = trailer_youtube
and whenever I try to run entertainment_center.py
it comes out with this:
Traceback (most recent call last):
File "C:/Users/Lukes/Desktop/media/entertainment_center.py", line 1, in <module>
import media
File "C:/Users/Lukes/Desktop/media\media.py", line 2
^
IndentationError: expected an indented block
The method __init__ is with the class scope. Indent it to consider that.
class Movie(object):
def __init__( self ):
self.id = 0
Plus, don't indent the top import instruction in the first file.

Im brand new to python and coding, im trying to get below working.
this is test code and if I can get this working I should be able to build on it.
Like I said im new to this so sorry if its a silly mistake.
# coding=utf-8
import ops # Import the OPS module.
import sys # Import the sys module.

# Subscription processing function
def ops_condition (o):
enter code herestatus, err_str = o.timer.relative("tag",10)
return status
def ops_execute (o):
handle, err_desp = o.cli.open()
print("OPS opens the process of command:",err_desp)
result, n11, n21 = o.cli.execute(handle,"return")
result, n11, n21 = o.cli.execute(handle,"display interface brief | include Ethernet0/0/1")
match = re.search(r"Ethernet0/0/1\s*(\S+)\s*", result)
if not match:
print("Could not determine the state.")
return 0
physical_state = match[1] # Gets the first group from the match.
print (physical_state)
if physical_state == "down":
print("down")
result = o.cli.close(handle)
else :
print("up")
return 0

The __getitem__ method for the regex match objects was only added since Python 3.6. If you're using an earlier version, you can use the group method instead.
Change:
physical_state = match[1]
to:
physical_state = match.group(1)
Please refer to the documentation for details.
I made first folder for Class Movie:
import webbrowser
class Movie():
def __init__(self,movie_title,movie_storyline,poster_image,trailer_youtube):
self.title=movie_title
self.storyline=movie_storyline
self.poster_image_url=poster_image
self.trailer=trailer_youtube
def show_trailer(self):
webbrowser.open(self.trailer)
Then in another file, I am trying to call the function:
import media
toy_story= media.Movie("toy_story","a boy who have toys","http://www.imdb.com/title/tt0114709/mediaviewer/rm3813007616","http://www.imdb.com/videoplayer/vi2052129305?playlistId=tt0114709&ref_=tt_ov_vi")
avatar=media.Movie("Avatar","A marine on an alien planet","http://www.imdb.com/title/tt0499549/mediaviewer/rm843615744","http://www.imdb.com/title/tt0499549/videoplayer/vi531039513?ref_=tt_ov_vi")
avatar.show_trailer()
But, I am getting below error:
AttributeError: Movie instance has no attribute 'show_trailer'
Any suggesions?
I think your indentation is wrong for your class Movie. I cant reproduce the problem with the following 2 files in the same folder - perhaps your method is not correctly indented to be part of the class:
media.py
import webbrowser
class Movie():
def __init__(self,movie_title,movie_storyline,poster_image,trailer_youtube):
self.title = movie_title
self.storyline = movie_storyline
self.poster_image_url = poster_image
self.trailer = trailer_youtube
def show_trailer(self):
print(self.trailer)
test.py
import media
toy_story=media.Movie("toy_story",
"a boy who have toys",
"http://www.imdb.com/title/tt0114709/mediaviewer/rm3813007616",
"http://www.imdb.com/videoplayer/vi2052129305?playlistId=tt0114709&ref_=tt_ov_vi")

avatar.show_trailer()

SyntaxError: invalid syntax
I have some other functions, not listed that use the input command sort of like a user interface, then it returns it to the larger class.
The places that the values are returned and what is return is:
line 8*: image_filename = input_class.input_file_name() # you would give a name of a picture here,
line 10*: chosen_function = input_function.input_vaild_function() # you Would give it either crop or translate can be sentence case or lowercase
line 11*: crop_values = input_crop_values.input_crop_data() # you would give it data in brackets like [1,2,3,4] and it would crop it.
line 15*: translate_values = input_translate.input_translate_data() # you would give it information in ( ), like (1,2,3,4) and it would translate it.
The code is acting really weird with the Boolean and the error message isn't helping me that much.
else, like other statements that come before a block, requires a colon.

I have a problem in class inheritance in Python; maybe it's not related to inheritance, but I have no other idea. I'm working with selenium web-driver. Here's the code I use:
from selenium import webdriver
class UIInterface(object):
def __init__(self):
self.driver = webdriver.Ie()
self.driver.get('URL')
def parentMethod(self, itemClassName = ''):
allElements = self.getAllElements()
return [el for el in allElements if el.get_attribute('type') == 'checkbox']
def getAllElements(self):
return self.driver.find_elements_by_tag_name('input')
class InterfaceChild(UIInterface):
def __init__(self):
super(InterfaceChild, self).__init__()
def childMethod(self):
returnedList = self.parentMethod(itemClassName = 'SomeClassName')
for item in returnedList:
print item.get_attribute('innerHTML')
This code gives me an error for line returnedList = self.parentMethod(itemClassName = 'SomeClassName'); the error description is this:
(<type 'exceptions.AttributeError'>, AttributeError("'InterfaceChild' object has no attribute 'self'",), <traceback object at 0x000000000418E5C8>)
I thought it might be related to inheritance, so I tried to put parentMethod and getAllElements in the class InterfaceChild; same exception raised. Any idea about this??
EDIT 1:
This is the main method for making instance of classes:
if __name__ == '__main__':
ieInterface = InterfaceChild()
ieInterface.childMethod()
This is the complete stack-trace:

I installed selenium with pip under Python 2.7 and changed the code to use Chrome driver[1] instead and changed the checker to make sure there would be some input tags being found. full code below. I'm running the code on Mac OS X. it works just fine.
So I guess the issue here is not the code. (Windows is not a friend of Python, perhaps :).
from selenium import webdriver
class UIInterface(object):
def __init__(self):
self.driver = webdriver.Chrome()
self.driver.get('http://duckduckgo.com')
def parentMethod(self, itemClassName = ''):
allElements = self.getAllElements()
result = [el for el in allElements]
print('===', result)
return result
def getAllElements(self):
return self.driver.find_elements_by_tag_name('input')
class InterfaceChild(UIInterface):
def __init__(self):
super(InterfaceChild, self).__init__()
def childMethod(self):
returnedList = self.parentMethod(itemClassName = 'SomeClassName')
for item in returnedList:
print item.get_attribute('innerHTML')
if __name__ == '__main__':
ieInterface = InterfaceChild()
ieInterface.childMethod()
The output looks like:

We are using the cocos2d framework to create a game. We're completely new to this framework, so we cannot get the director object to work as we are expecting. Here is our code skeleton:
from cocos.director import director
from cocos.layer import base_layers
import sys
import math
import os
import pyglet
import cocos
world_width = 1000
world_height = 1000
class NetworkMap(cocos.layer.ScrollableLayer):
def __init__(self, world_width, world_height):
self.world_width = world_width
self.world_height = world_height
super(NetworkMap, self).__init__()
bg = ColorLayer(170,170,0,255,width=500,height=500)
self.px_width = world_width
self.px_height = world_height
self.add(bg,z=0)
class TestScene(cocos.scene.Scene):
def __init__(self):
super(TestScene,self).__init__()
def on_enter():
director.push_handlers(self.on_cocos_resize)
super(TestScene, self).on_enter()
def on_cocos_resize(self, usable_width, usable_height):
self.f_refresh_marks()
def main():
scene = TestScene()
director.init(world_width, world_height, do_not_scale=True)
world_map = NetworkMap(world_width, world_height)
scroller = cocos.layer.ScrollingManager()
scroller.add(world_map)
scene.add(scroller)
director.run(scene)
So for some reason the director doesn't have all the attributes we want.
Our stack trace is:
Traceback (most recent call last):
File "map.py", line 49, in <module>

File "map.py", line 39, in main

You need to initialise the director before you instantiate your first scene. The director is the global object that initialises your screen, sets up the Cocos2D framework, etc.
I found a few other errors:
You need to change ColorLayer to be fully qualified, e.g. cocos.layer.ColorLayer.
on_enter needs to have self as the first argument.
You need to define f_refresh_marks in your TestScene class.
Here's a working copy of the code. (Working, in the sense that it does not throw errors, not that it does any sort of scrolling.)
from cocos.director import director
from cocos.layer import base_layers
import sys
import math
import os
import pyglet
import cocos
world_width = 1000
world_height = 1000
class NetworkMap(cocos.layer.ScrollableLayer):
def __init__(self, world_width, world_height):
self.world_width = world_width
self.world_height = world_height
super(NetworkMap, self).__init__()
bg = cocos.layer.ColorLayer(170,170,0,255,width=500,height=500)
self.px_width = world_width
self.px_height = world_height
self.add(bg,z=0)
class TestScene(cocos.scene.Scene):
def __init__(self):
super(TestScene,self).__init__()
def on_enter(self):
director.push_handlers(self.on_cocos_resize)
super(TestScene, self).on_enter()
def on_cocos_resize(self, usable_width, usable_height):
self.f_refresh_marks()
def f_refresh_marks(self):
pass
def main():
director.init(world_width, world_height, do_not_scale=True)
scene = TestScene()
world_map = NetworkMap(world_width, world_height)
scroller = cocos.layer.ScrollingManager()
scroller.add(world_map)
scene.add(scroller)
director.run(scene)
if __name__ == '__main__': main()
I had the same issue (with a very similar stack trace) and it was because I was trying to create a layer before calling director.init(). Moving director.init() to earlier in the code fixed it for me.
