Learning WebScraping

[Prince_Bhatia]

I am very new to web scraping. I am learning web Scraping online.
website i am trying to scrape is http://econpy.pythonanywhere.com/ex/001.html
i have written a code that will scrape

from bs4 import BeautifulSoup
from urllib.request import urlopen

url = urlopen("http://econpy.pythonanywhere.com/ex/001.html")

def getTitle():
    global url
    bs0bj = BeautifulSoup(url, "html.parser")
    for i in bs0bj.find_all(title="buyer-name"):
        print(i.get_text())
getTitle()


#def getTitle():
#    global url
#    bs0bj = BeautifulSoup(url, "html.parser")
#    for i in bs0bj.find_all(title="buyer-info"):
#        print(i.get_text())
#getTitle()

def getPrice():
    global url
    bs0bj = BeautifulSoup(url, "html.parser")
    for i in bs0bj.find_all("span", {"class":"item-price"}):
        print(i.get_text())
getPrice()

now there are few questions:(please uncomment the codes)
Q1: when i run this code using buyer info it prints price,how to get the data of next pages also?
Q2: why it doesn't print price , when run individually(just buyername)?
Q3: how to write these data into CSV?
