I cant print horizontally

I want to make a book catalog, the output is to print horizontally and change line for every 3 books. I understand that we can do a print horizontal by using:
end = ""
BUT that only works for 1 line. As my output has 3 line like Title, ISBN, Price, if I using end = "", it can't get it done.
Below is my code
line_format = "{:50s} \n{:6s} - {:13s} \n{:11s}"
books = db.get_books(kel)
for book in books:
print((line_format.format(str(book.title),
str(book.isbn),
"Rp. {:,}".format(book.price).replace(",","."))))
What I got is:
Deaver - Never Game A/UK
9780008303778
Rp. 161.000
Poirot - DEATH ON THE NILE (Exp]
9780008328948

webscraping with selenium to click a button and grab everything

I have been working on this scraper for a while and I think it could be improved but I'm not sure where to go from here.
The initial scraper looks like this and I believe it does everything I need it to do:
url = "https://matrix.heartlandmls.com/Matrix/Public/Portal.aspx?L=1&k=990316X949Z&p=DE-74613894-421"
h_table = []
driver = webdriver.Firefox()
driver.get(url)
driver.find_element_by_xpath("/html/body/form/div[3]/div/div/div[5]/div[3]/span[2]/div/div/div[2]/div[1]/div/div/div[2]/div[2]/div[1]/span/a").click()
time.sleep(10)
i = 200
while i > 0:
h_table.append(driver.find_element_by_id("wrapperTable").text)
driver.find_element_by_xpath("/html/body/form/div[3]/div/div/div[5]/div[2]/div/div[1]/div/div/span/ul/li[2]/a").click()
time.sleep(10)
i -= 1
this outputs everything into a table which i can clean up

however, I had seen some other examples with WebDriverWait, but so far I have been unsuccessful, I think it would greatly speed up the scraper, here's the code I wrote

url = "https://matrix.heartlandmls.com/Matrix/Public/Portal.aspx?L=1&k=990316X949Z&p=DE-74613894-421"

xpath = '/html/body/form/div[3]/div/div/div[5]/div[2]/div/div[1]/div/div/span/ul/li[2]/a'
driver = webdriver.Firefox()
driver.get(url)
driver.find_element_by_xpath("/html/body/form/div[3]/div/div/div[5]/div[3]/span[2]/div/div/div[2]/div[1]/div/div/div[2]/div[2]/div[1]/span/a").click()
time.sleep(10)
while True:
button = driver.find_elements_by_xpath("/html/body/form/div[3]/div/div/div[5]/div[2]/div/div[1]/div/div/span/ul/li[2]/a")
if len(button) < 1:
print('done')
break
else:
h_table.append(driver.find_element_by_id("wrapperTable").text)
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, 'xpath'))).click()
this seems to give all the results, but it gives duplicates and I couldn't stop it without a keyboard interrupt
calling len(h_table) = 258, where it should be 200

if the length of your list is the problem, why not using :
if len(h_table) >= 200:
print("done")
break

confusion about creating a conversational alexa skill using Flask-Ask and python: it goes to FallBackIntent when required slot missing

I want to create a conversational alexa skill using Flask-Ask and python 3. But when I intentionally omit the required slot. Alexa doesn't prompt me anything. It goes to FallBackIntent directly. I've set the prompt and corresponding answer for it in the web console and I've added necessary code to check if dialogState!= 'COMPLETED' and return delegate(). But it just go to FallBackIntent directly.
Below is a screenshot of my settings for the slot on the web console

Tkinter error type variable [duplicate]

This question already has answers here:
Why is my Button's command executed immediately when I create the Button, and not when I click it? [duplicate]
(5 answers)
Closed 6 years ago.
I am an electrical engineer and I am new to Python programming.
I want to write a Python program for three phase transformer calculator. The program is very simple, it does just a few algebraic operation; I wrote simple python code without GUI and it worked very fine. So I decided to make the same program using Tkinter module to give a GUI to my application. I had some error and I read a lot of questions and asked many questions on this community, but I am not able to solve it. I am not able to trace the cause of the error. The code is:

The first kind of error I had was a ValueError: could not convert string to float. I read this could happen because at the start time, the entry widgets are empty so python can convert it to float. So I added try/except block. Now when I start the program, it prints an error message in except block (I can't understand this: the calcola function is associated to the calculate button, but it seems to run the function without button press, at start time) then don't happen anything else, though writing number in entry box and pressing calculate button. What I suspect is that the way I am using function is wrong (syntax or something else). If anyone can help me, I'd really appreciate.
Sorry for bad English. Thank you very much.

when passing parameters through your function if it is called by a tkinter button you should always use the lambda statement like this: Button(finestra,text='Calcola',command=lambda: calcola(paramaters..) or the function will be called just once when the program starts.

Python QtreeWidget: return tree hierarchy

I got stuck in trying to obtain the hierarchical view of a widget tree.
The code works fine and generates a nice tree like that:
ROOT(Animal):
|
|
|___Not extinct:
. | (red)
. |_____BIRD--------------(blue)
. | (green)
|
| (red)
|_____Mammal------------(blue)
| (green)
|
| (red)
|_____Reptile-----------(blue)
(green)
Here is the code with the tree hierarchy:
def myTreeWDG(self):
....
"""define tree"""
self.obj_animalTreeWDG = QtGui.QTreeWidget(self.obj_viewGroupBox)
self.obj_animalTreeWDG.setGeometry(QtCore.QRect(10, 20, 191, 131))
self.obj_animalTreeWDG.setObjectName("obj_animalTreeWDG")
"""ROOT: animal"""
obj_parent1 = QtGui.QTreeWidgetItem(self.obj_animalTreeWDG)
"""not extinct:"""
obj_childView1_1 = QtGui.QTreeWidgetItem()
obj_parent1.addChild(obj_childView1_1)
"""bird"""
obj_childView1_1_1 = QtGui.QTreeWidgetItem()
obj_childView1_1.addChild(obj_childView1_1_1)
"""3: red, blue, green"""
total=3
self.insert_treeLeaves(total,obj_childView1_1_1)
"""mamal"""
obj_childView1_1_2 = QtGui.QTreeWidgetItem()
obj_childView1_1.addChild(obj_childView1_1_2)
"""3: red, blue, green"""
total=3
self.insert_treeLeaves(total,obj_childView1_1_2)
"""reptile"""
obj_childView1_1_3 = QtGui.QTreeWidgetItem()
obj_childView1_1.addChild(obj_childView1_1_3)
"""3: red, blue, green"""
total=3
self.insert_treeLeaves(total,obj_childView1_1_3)
"""connect event"""
QtCore.QObject.connect(self.obj_animalTreeWDG, QtCore.SIGNAL('itemClicked(QTreeWidgetItem*, int)'), self.obj_treeViewInput)
Here is the code to add the leaves into the tree:
def insert_treeLeaves(self,total,tree_directParent):
for i in range(0,total):
"""leaves with color name"""
tree_child_leaf = QtGui.QTreeWidgetItem()
tree_directParent.addChild(tree_child_leaf)
Then, we have the function that tells us every time the tree is clicked, and where it was clicked:
def obj_treeViewInput(self,item,col):
print "obj _Qtree : pressed"
print "name:" item.text(col)
The problem is, how can we get if the touched leaf (red) belongs to the Bird or other father, i.e. how to get the following output give some mouse click:
Animal - Not extinct - Mammal - (red).
All comments and suggestions are highly appreciated.

What about a method in each QtreeWidgetItem in which you could print the path to this item.
In this method, you could use recursion to get the complete path of the item's parents (you have a "QTreeWidgetItem * parent () const" method to do this) and you add the current item's text to its parent's path ! You stop the recursion when an item do not have any parent.
I hope I understood your question and this helps you a little bit !
Do you have your own QTreeWidgetItem class ? You could use a specific role to achieve this...
