Thủ Thuật Hướng dẫn Bảng javascript cạo web python 2022
Lê Thùy Chi đang tìm kiếm từ khóa Bảng javascript cạo web python được Cập Nhật vào lúc : 2022-12-16 05:25:10 . Với phương châm chia sẻ Bí kíp về trong nội dung bài viết một cách Chi Tiết 2022. Nếu sau khi đọc tài liệu vẫn ko hiểu thì hoàn toàn có thể lại Comments ở cuối bài để Tác giả lý giải và hướng dẫn lại nha.Scraping là một kỹ năng rất thiết yếu cho mọi người để lấy tài liệu từ bất kỳ trang web nào. Cạo và phân tích cú pháp một bảng hoàn toàn có thể là việc làm rất tẻ nhạt nếu tất cả chúng ta sử dụng trình phân tích cú pháp Beautiful soup tiêu chuẩn để thao tác đó. Do đó, ở đây chúng tôi sẽ mô tả một thư viện với sự trợ giúp của bất kỳ bảng nào hoàn toàn có thể được lấy từ bất kỳ trang web nào một cách thuận tiện và đơn giản. Với phương pháp này, bạn thậm chí không phải kiểm tra phần tử của trang web, bạn chỉ việc đáp ứng URL của trang web. Thế là xong và việc làm sẽ hoàn thành xong trong vài giây

Bạn hoàn toàn có thể sử dụng pip để setup thư viện này
pip install html-table-parser-python3Bắt đầu
Bước 1. Nhập những thư viện thiết yếu thiết yếu cho tác vụ
# Library for opening url and creating # requests import urllib.request # pretty-print python data structures from pprint import pprint # for parsing all the tables present # on the website from html_table_parser.parser import HTMLTableParser # for converting the parsed data in a # pandas dataframe import pandas as pdBước 2. Định nghĩa một hiệu suất cao để lấy nội dung của trang web
# Opens a website and read its # binary contents (HTTP Response Body) def url_get_contents(url): # Opens a website and read its # binary contents (HTTP Response Body) #making request to the website req = urllib.request.Request(url=url) f = urllib.request.urlopen(req) #reading contents of the website return f.read()Bây giờ, hiệu suất cao của chúng tôi đã sẵn sàng, vì vậy chúng tôi phải chỉ định url của trang web mà chúng tôi cần phân tích bảng
Ghi chú. Ở đây tất cả chúng ta sẽ lấy ví dụ về moneycontrol. com vì nó có nhiều bảng và sẽ giúp bạn làm rõ hơn. Bạn hoàn toàn có thể xem trang web tại đây.
Bước 3. Bảng phân tích cú pháp
# defining the html contents of a URL. xhtml = url_get_contents('Link').decode('utf-8') # Defining the HTMLTableParser object p = HTMLTableParser() # feeding the html contents in the # HTMLTableParser object p.feed(xhtml) # Now finally obtaining the data of # the table required pprint(p.tables[1])Mỗi hàng của bảng được tàng trữ trong một mảng. Điều này hoàn toàn có thể được quy đổi thành khung tài liệu gấu trúc một cách thuận tiện và đơn giản và hoàn toàn có thể được sử dụng để thực hiện bất kỳ phân tích nào.
