How to express not equal in python

Recommended manual: Python basic introductory tutorial

In the Python language , use != to indicate not equal. We understand through the following simple example:

How to express not equal in python

In the above example, variables x and y are assigned values first, and then the if statement is used to determine whether x and y are equal. , if they are not equal, print the value of x y; if they are equal, print the value of x - y. Obviously, x is not equal to y, and the result is the value of x y, which is 17. In the above example, != is the inequality symbol, which is formed by! Used in combination with =.

Another example, as follows

How to express not equal in python

We use Python to verify that 40 is not equal to 40, and the returned result is False, which is wrong ;Verify that 45 is not equal to 48, and the result returns True. Verify that list a and list b are equal. False is also returned because they are not equal!

So far, we have mastered how to express inequality in Python, which is represented by !=. Not only can it determine whether two numbers and lists are equal, it can also verify whether two strings, tuples, dictionaries, or sets are equal!

How to Use Python to Find the Zipf Distribution of a Text FileMar 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 PythonMar 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
