Slicing in Python is a powerful feature that allows you to extract specific elements or sections from sequences like lists, strings, and tuples. It provides a concise and efficient way to work with subsets of data without needing to iterate through the entire sequence. In this article, we'...
Sockets are essential for establishing connections and facilitating communication between two or more nodes over a network. Web browsing is an example of socket programming. The user requests the web server for information, and the server processes the request and provides the data. In Python, for ...
Here's an example of how to define a simple class in Python:class Cat:class Cat: def __init__(self, name, age): self.name = name self.age = age def bark(self): return "Miu! Miu!" def get_age(self): return self.age def set_age(self, new_age): self.age = new_age ...
Python is often described as a “glue language,” meaning it can let disparate code (typically libraries with C language interfaces) interoperate. Its use in data science and machine learning is in this vein, but that’s just one incarnation of the general idea. If you have applications or ...
Another major project, still in its infancy, is removing CPython’s Global Interpreter Lock (GIL), a thread-synchronization mechanism that’s kept Python threads from being properly concurrent. Removing the GIL is a complex project, since one of the requirements imposed is that it can’t make...
so it allows for pieces of code blueprints to be reused across programs. It is also multithreaded, meaning it allows for the creation of multiple execution threads with each thread concurrently executing specific tasks. Finally, Java is popular because it is secure, architecture-neutral and can of...
Clear, detailed documentation is essential to the success of your API. For example, when you describe a date, you need to be clear on format. In Europe, a date is typically represented as day, month, then year, while in North America, the order is month, day, year. Not being explicit...
Besides the process versus thread misconception, multiprocessing is sometimes confused with multiprogramming, or the interleaved execution of two or more programs by a processor. Today, the term is rarely used as all but the most specialized computer OSes support multiprogramming. While multiprocessing ...
Our customer mentioned that inserting data (100.000 rows) is taking 14 seconds in a database inBusiness Critical. I was able to reproduce this time using a single thread using a table with 20 columns. In order to improve this Python code, I suggested to run...
JUnit 4 Test – Example 1 In this example, we will have the test fixtures in the class with three test cases. The setUp() method with @Before annotation and tearDown() method with the @After annotation. Code: package demo.tests;
