Stock price data refresh

Question

I am very new and I am getting totally stuck with recent task. I want to autorefresh stock price automatically as it is changing. I am scrapping nasdaq.com website for actual intraday price. I have a recent code:

import bs4 as bs
import urllib
tiker = input("zadaj ticker: ")
url = urllib.request.urlopen("http://www.nasdaq.com/symbol/"+tiker+"/real-time")
stranka = url.read()
soup = bs.BeautifulSoup(stranka, 'lxml')
print (tiker.upper())
for each in soup.find('div', attrs={'id': 'qwidget_lastsale'}):
    print(each.string)

I was only able to make an infinite loop while True but i get prints in lines despite i want to change only one line as actual price is changing. very thank you for your notes.

Answer 1

You can achieve it by printing "\b" to remove the previously printed string and then printing on the same line:

import bs4 as bs
import urllib
import time
import sys

tiker = input("zadaj ticker: ")
print (tiker.upper())
written_string = ''
while True:
    url = urllib.request.urlopen("http://www.nasdaq.com/symbol/"+tiker+"/real-time")
    stranka = url.read()
    soup = bs.BeautifulSoup(stranka, 'lxml')
    for each in soup.find('div', attrs={'id': 'qwidget_lastsale'}):
        for i in range(len(written_string)):
            sys.stderr.write("\b")
        sys.stderr.write(each.string)
        written_string = each.string
    time.sleep(1)
