5 recommended articles about any key

Preface To implement this function, all you need is to pause the program, wait and capture a keyboard input from the user, and then continue execution. Python has built-in libraries that can help us implement this function, but Windows and Linux must be treated differently. The getch() method in msvcrt can help to implement it under Windows. Its function is to obtain a key response and return the corresponding character. It is not echoed on the command line. There is the following program segment: import msvcrt print ord(msvcrt.getch()) Here, ord is used to convert the obtained characters into ASCII values. For example, capturing the key "d" (note that it is lowercase) will get the value 100. What about Linux? Well, it’s a little bit complicated, but it’ll be easier if you clarify your thoughts first. First of all, you need to know the three modes of the Linux terminal, which are canonical mode, non-canonical mode and raw mode: Canonical mode Canonical mode, also called cooked mode, is a common mode for users. The characters entered by the driver are saved in the buffer and are only received when

How to Use Python to Find the Zipf Distribution of a Text File How to Use Python to Find the Zipf Distribution of a Text File Mar 05, 2025 am 09:58 AM

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

How to Work With PDF Documents Using Python How to Work With PDF Documents Using Python Mar 02, 2025 am 09:54 AM

PDF files are popular for their cross-platform compatibility, with content and layout consistent across operating systems, reading devices and software. However, unlike Python processing plain text files, PDF files are binary files with more complex structures and contain elements such as fonts, colors, and images. Fortunately, it is not difficult to process PDF files with Python's external modules. This article will use the PyPDF2 module to demonstrate how to open a PDF file, print a page, and extract text. For the creation and editing of PDF files, please refer to another tutorial from me. Preparation The core lies in using external module PyPDF2. First, install it using pip: pip is P
