with open(r'.htmlmyTest.html') as rf:
with open(r'.htmlnew2.html','a') as wf:
for data in rf.readlines():
if data.__contains__('<a href'):
list_urls=data.split(""")
for link in list_urls:
if "www" in link:
wf.write(link+"n")
we can also use count and a for loop for simplification in previous program!!!
We can also do as batter solution:
with open("file.html","r") as html_file:
with open("output_file.txt","a") as output_file:
for line in html_file.readlines():
position = line.find("<a href=")
for i in range(line.count("<a href=")):
firstquate_position = line.find('"',position)
secondquate_position = line.find('"',firstquate_position+1)
url = line[firstquate_position+1:secondquate_position]
# print(url)
output_file.write("==> "+url+"n")
position = secondquate_position + 1
Note : This is 100% working try it
Hello sir!! Here May I use page.seek(second_quote) instead of page=page[second_quote: ] ?
with open("helpEx1",'r') as f1:
with open("helpEx2",'a') as f2:
for line in f1.readlines():
pos_com=-1
f_quote=pos_com
while(line.find(".com",pos_com+1)!=-1):
pos_com=line.find(".com",pos_com+1)
f_quote=line.find(""",f_quote+1)
l=line[f_quote+1:pos_com+4]
f2.write(f"{l}n")
f_quote=pos_com+5
continue
Sir Check me out ..
More enhanced way
#program to extract n no. of links in one line links
target = r'B:Python CourseCh18_Working_with_filesCh18_Ex2html.txt'
extract = r'B:Python CourseCh18_Working_with_filesCh18_Ex2extract.txt'
def url_finder(link):
if "href" in link:
comma_split = link.split('"') # ' " '
return [each for each in comma_split if each[-4: ].lower() == ".com" ]
def transfer(target, extract):
with open(target) as rf:
with open(extract, 'w') as wf:
for line in rf.readlines():
contain_url = url_finder(line)
if contain_url != None:
for extractedLink in contain_url:
wf.write(f"n> {extractedLink}")
wf.close()
rf.close()
transfer(target, extract)
Dear sir, please help. I thought this should work, but it isn't. Please tell if there is some error. It returns the result as the previous code.
with open('Webpage.htm', 'r') as rf:
with open('output.txt', 'w') as wf:
for line in rf.readlines():
if 'a href' in line:
l1 = line.split(""")
for l in l1:
if 'www' in l:
wf.write(f"{l}n")
How about this way?
import re
with open('./data.txt') as webpage:
urls = re.findall(r'(http[^"]+|www[^"]+)', webpage.read())
for u in urls:
print(u)
