You need to tell us which OS, Python version and GUI toolkit you are using. > [image: Inline image 1] This is a text list so images usually get stripped off. If absolutely necessary to send an image use a link to an image gallery somewhere. But at least try to explain what you are trying to show us. > Is there any function which I can use for this (like we have entry.get to > get the value similar any function to put the value) Assuming you are using Tkinter there is an insert() method. To put text at the end of the entry use import tkinter as tk myText = "Hello world" top = tk.Tk() myEntry = tk.Entry(top) myEntry.pack() myEntry.insert(tk.END,mytext) top.mainloop() However a common alternative is to use a StringVar and associate it with the Entry so that changes in the StringVar are automatically shown in the Entry and changes in the Entrey are reflected to the StringVar. Most Tkinter tutorials will show that under StringVar. Of course if you are not using Tkinter most of that will be useless! -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

[Tutor] beautifulsoup
I am trying to scrap from the (span class= 'Number'). The code looks
like this on the pages I am scrapping:
99 10.00(-0.1%)
Menu
Max Quantity
100.000
Average Quantity
822
Previous Order
96
Max Price
104
Number of Trades
383
Min Price
59
Total Amount
800
Start
10
Low
98
I have tried to use Beautifulsoup to scrape the data. However, it
returns Nothing on the screen
from bs4 import BeautifulSoup
html = response.content
soup = BeautifulSoup(html,"html.parser")
title = soup.select('td.styleB')[0].next_sibling
title1 = soup.find_all('span', attrs={'class': 'Number'}).next_sibling
print(title1)
I am hoping that I could retrieve the number as follows:
Max Quantity: 100
Average Quantity: 822
Previous Order: 96
Max Price: 104
Number of Trades:383
Min Price: 59
Total Amount:800
Start:10
Low: 98
Please advise what is the problem with my code from handling the
query. Thank you

You perform several steps here before your print. Break them up. "soup.select",
"[0]", "next_sibling" etc and print the intermediate values along the way.
As a wide guess, might:
title = soup.select('td.styleB')[0].next_sibling
fetch this?
I also suspect that next_sibling returns the next tags in the DOM tree. Not
text. Your title1 might come out better as:
title1 = str(soup.find_all('span', attrs={'class': 'Number'})[0])
if I recall how to grab the text inside a tag. Also, don't you want a loop
around your find_all?
Eg:
for tag in soup.find_all('span', attrs={'class': 'Number'}):
print(tag)
print(str(tag)) # or tag.text() ?
Anyway, put in more print()s in the middle of your traversal of the DOM. That
should show where things are going wrong.
