Checking to see if a directory exists and then creating it if it is not present requires a few lines of code. Isn't Python great. Begin by importing the os module and use the exists and makedirs functions.

import os

if os.path.exists(somedirectory):
   os.makedirs(somedirectory)

Working With Strings In Python

In this tutorial we are going to take a look at how you work with strings in Python. Now, any language worth its salt will have a number of options for working with text and Python is probably one of the best to use when it comes to processing text.

If you are new to programming in general you may be wondering what a string is. In terms of programming, a string is classed as any sequence of characters you can type with your keyboard, and let’s face it, if you want your application to be of any use to yourself or other users then you need it to tell you what it’s doing or to prompt you for an action, and that is where strings come into play.

They are your applications way of communicating with the user. Without the ability to enter and display text or software would be pretty useless.

So, how would you create a string in Python? Take a look at the following code:

Common Computer Problems and How to Fix Them

Technology is wonderful. It helps us run our businesses and connects us to the world. But when computer problems get in the way of getting what you need to get done, you can go from easygoing to mad-as-a-hornet in 3 seconds flat. Before you panic or give in to the temptation to throw your computer out the window, try these easy fixes.

5 Common Computer Problems

Sluggish PC

A sluggish PC often means low disk space caused by an accumulation of temporary Internet files, photos, music, and downloads. One of the easiest fixes for a slow PC is to clear your cache.

The way you’ll do this will depend on the Internet browser you use:

Chrome– On the top right-hand side of the screen, you’ll see what looks like a window blind. Click on that. Click on ‘History’ and hit ‘Clear Browsing Data’.

Safari– On the upper left-hand side, you’ll see a tab marked ‘Safari’. Click on that. Scroll down and hit ‘Empty Cache’.

Internet Explorer– Click on ‘Tools’ and scroll down to ‘Internet Options’. Under ‘Browsing History’ click ‘Delete’. Delete files and cookies.

FireFox – At the top of the window click ‘Tools’ then go to ‘Options’. Select the ‘Advanced’ panel and click on the ‘Network’ tab. Go to ‘Cached Web Content’ and hit ‘Clear Now’.

.NET Core 3 Release, Major Benefits

[Mar, 26, 2019] |
Tags:

On March 6 of this year, Microsoft's .NET Foundation released its third preview release of .NET Core 3 — which is its free and open-source framework for developing apps on Windows, MacOS and Linux — with an official release scheduled for later this year. This release brings a wealth of new features and enhancements. This includes the following:

1. Windows Desktop Support

One of the biggest additions to version 3.0 of the framework is the ability to develop Windows desktop applications. The new Windows Desktop component lets you build applications using either the Windows Presentation Foundation (WPF) graphical subsystem or the Windows Forms graphical class library. You can also use Windows UI XAML Library (WinUI) controls in your applications.

The Windows Desktop component is only supported and included on Windows installs.

2. Support for C# 8

The new framework has support for C# 8, which includes not only the ability to create asynchronous steams but features such as:

Index and Range data types

Using declarations

Switch expressions

The Index and Range data types make array manipulation easier, while Using declarations ensure that your objects get disposed once they are out of scope. Finally, Switch expressions extend Switch statements by allowing you to return a value.

3. IEEE Floating-Point Improvements

The new framework includes floating point APIs that comply with IEEE 754-2008. This includes fixes to both formatting and parsing as well as new Math APIs such as:

BitIncrement/BitDecrement

MaxMagnitude/MinMagnitude

ILogB

ScaleB

Log2

FusedMultiplyAdd

CopySign

4. Support for Performance-Oriented CPU Instructions

The new framework includes support for both SIMD and Bit Manipulation instruction sets, which can create significant performance boosts in certain situations, such as when you are processing data in parallel.

5. Default Executables

With the new framework, you can now produce framework-dependent executables by default without having to use self-contained deployments.

6. Local dotnet Tools

In the previous version of the framework, there was support for global dotnet tools. But the current version adds support for local tools as well. These tools are associated with a specific disk location, and this allows you to enable per-repository and per-project tooling.

7. Support for MSIX Deployments

The new framework supports MSIX, which is a Windows app package format that you can use when deploying Windows desktop applications.

8. Built-In and Fast JSON Support

In prior versions of the framework, you had to use Json.NET if you wanted JSON support in your application. The framework, though, now has built-in support that is not only fast but also has low allocation requirements. It also adds 3 new JSON types, which include:

Utf8JsonReader

Utf8JsonWriter

JsonDocument

9. Cryptography Support

The new framework supports AES-GCM and AES-CCM ciphers. It also supports the importing and exporting of asymmetric public and private keys from a variety of formats without the need of an X.509 certificate.

Platform Support

.NET Core 3 supports the following operating systems:

Alpine: 3.8+

Debian: 9+

Fedora: 26+

macOS: 10.12+

openSUSE: 42.3+

RHEL: 6+

SLES: 12+

Ubuntu: 16.04+

Windows Clients: 7, 8.1, 10 (1607+)

Windows Servers: 2012 R2 SP1+

The framework further supports the following chips:

x64 (Windows, macOS and Linux)

x86 (Windows)

ARM32 (Windows and Linux)

ARM64 (Linux)
