How to scrape data from website？

 In the future, more and more libraries will use Python as the front end (improving programming efficiency) and Rust as the back end (improving performance). python Rust is replacing C as the “backend” for high-performance Python packages. What is the reason behind this? First, let’s consider motivation. Python is easy to write, but has the problem of slow execution speed. I especially can’t write data processing libraries because Python is very slow and it’s difficult to write high-performance libraries in pure Python. However, Python is the primary language for machine learning and data engineering. So when you try to write a library for data engineers or machine learning engineers, you run into the following problems: Although we need to write APIs in Python, high-performance data processing tasks cannot be done solely in Python. This means that you have the following options for writing a library: Either you learn and use C, or someone else learns C, writes a library, and you r...

  Due to the rapid development of artificial intelligence (AI) technology, it is gradually permeating various fields, one of which is the field of programming. The advent of AI programming tools has had a huge impact on programming, bringing unprecedented convenience and efficiency to programmers. This article introduces some AI programming tools to make your programming work more convenient. 1. GitHub Copilot GitHub Copilot is a programming support tool jointly developed by OpenAI and GitHub. Automatically generate code and make suggestions using AI models. When programmers write code, they simply enter comments and code snippets, and Copilot automatically generates the appropriate code. It learns from a vast open source code repository and supports many programming languages. Therefore, it supports various code situations and provides codes with high accuracy. In addition to automatically generating code, it also provides support for writing programs efficiently, such as suggesti...

 The main reason for low data quality is the existence of dirty data in the database and data input errors. Different representation methods and inconsistencies between data caused by data from different sources are the cause of dirty data. Therefore, before data analysis, we should first perform data cleaning. Data cleaning is a process of collecting and analyzing data, re-examining and verifying data. Its purpose is to deal with different types of data, such as missing, abnormal, duplicate and illegal, to ensure the accuracy, completeness, consistency, validity and uniqueness of the data. Let’s take a look at 4 commonly used data cleaning tools. 1. IBM InfoSphere DataStage IBM InfoSphere DataStage is an ETL tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere. It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition, the Enterprise Edition, and the MVS Edition. It uses a cli...
