...ANSWER
Answered 2021-Apr-25 at 03:19With Selenium:
Click an image from search results.
Wait until the image is visible.
image_link = driver.find_element_by_css_selector(".tvh9oe.BIB1wf .eHAdSb>img").get_attribute("src")
You can use the same locator for bs4

QUESTION
I have some data that describes an ordered set of discrete events (or states). There are 34 possible states, which may occur in any order and may repeat. Each sequence of events can contain any number of events, and crucially there are more than 2 sequences of events. My eventual aim is to cluster these sequences into similar subsets, but my hunch is that this cannot be meaningful unless these sequences are aligned such that equivalent events occupy the same position in all sequences.
I'm very familiar with multiple alignment of biological sequences, but all the software I've come across for this (MUSCLE, MAFFT, T-COFFEE, Clustal*, etc) require DNA, RNA or AA sequences, and I have more states than any of these, so I can't get them to work.
I've found various implementations of the pairwise alignment algorithms such as Needleman-Wunsch in R, but so far haven't come across any generic (non-biological) implementations of any multiple sequence alignment algorithms.
For example, say my data looks like this:

QUESTION
I am new to kivy and need help with the ListView and ScreenManager. I managed to use the ListView on a single screen, but I am trying to use it with two screens via ScreenManager: I have a ListView in MainScreen and made a button to navigate to ProfileScreen, where I will enter values in the TextInput "abc" and "defe" and want them to be submitted to the ListView. When I run the .py file with this code it works, but when I enter the values on ProfileScreen and press "Okay", it crashes and says "ProfileScreen" has no attribute "student_list". If I change the parameter of ProfileScreen(Screen) to ProfileScreen(MainScreen) it works, but the content of the page ProfileScreen is inherited from MainScreen, which I don't want.
How can I solve this issue? I would appreciate any kind of help, thanks in advance.
This is my code:
studentdb.py, studentdb.kv
...ANSWER
Answered 2018-May-16 at 22:19The error in your case is that student_list is an attribute of MainScreen and not ProfileScreen so you can not access it by self, I recommend reading the following: What is the purpose of self?
In your case, the solution is to access the correct Screen through the ScreenManager:
QUESTION
I'm new in stackoverflow and I'd like to make my first question for a problem in this code I've tried to write to learn objects in python.
I'm trying to call the creation of an object through a dictionary.
My purpose is to create an object thanks to a number, for example I have the dictionary newch = {1 : Character.new_dragon(), 2 : Character.new_goblin()} and when I call Player1 = newch[1] it should create a new dragon (@classmethod new_dragon) and assign it to Player1
The problem is that when i run the program, Character.new_dragon() and Character.new_goblin() are called automatically (i put a control print), but when I write "DRAGO" after the request "which player?" the functions aren't called because there isn't the control print
ANSWER
Answered 2017-Aug-01 at 10:28When you are initialising the dictionary this way:
newch={1:Character.new_dragon(),2:Character.new_goblin()}
You are binding keys (1 and 2) to the return values of the new_dragon and new_goblin functions. You need to bind the functions(without calling them) like so:
newch={1:Character.new_dragon,2:Character.new_goblin}
Notice there are no brackets!
And then, when you create players, you execute those functions like so:
play[i]=newch[1]() Notice here we have brackets!
Additionally, if I may suggest an improvement of the code here:
