Category: .NET Core

I have read the article https://www.red-gate.com/simple-talk/development/dotnet-development/10-reasons-python-better-than-c-sharp

I think that deserves an answer –  so I take all points to answer to them. You can replicate the code in C# 10 / .NET 6 with a globalusings.cs with the following content:

global using static System.Console;
global using static System.Linq.Enumerable;
global using static System.IO.Directory;
global using static System.String;
global using static System.Math;

So let’s start:

Point 1 - Indented code blocks

//Point 1 - Indented code blocks
//With curly braces I can indent whatever way I want - I am not constrained

using System.Collections.Generic;

foreach (var i in Range(1, 11))
{
if (i % 3 == 0)
WriteLine("fizz");
else if (i % 5 == 0)
WriteLine("buzz");

}

Also , when I want to comment something , with C# I know when the else if is
terminating without counting tabs. Just see where the { is closing with }

Point 2 -  Self-declaring Variables

Seriously? What is the difference between Python
//meaning_of_life = 42
and C# ? Just a var ?

//Point 2 - Self-declaring Variables
var meaning_of_life = 42;

Point 3 -– Those modules

It is the same code as Python

foreach (var file in EnumerateFiles(@"C:\")){
 WriteLine(file);
}

Point 4 – Simplicity of Data Structures

Quoting : Purists will say that you need all the different data types that C# provides, but trust me, you don’t.

Point 5 - Slicing

Same code in C#

var sins = new[]{ "pride", "envy", "gluttony", "greed", "lust", "sloth", "wrath" };
//var selected_sins = sins[1..(sins.Length-1)];
var selected_sins = sins[1..^1];
WriteLine(Join(" ", selected_sins));

Point 6 – For loops

Same syntax in C#

foreach (var i in Range(0,5))
{
WriteLine(i);
}
// words in a string
string[] words = { "Simple", "Talk" };
foreach (string word in words)
{
WriteLine(word);
}

Quoting : “(unlike in C#, where sometimes you use for and sometimes foreach)”
Please enumerate an array backwards in python without reversing

7 – List comprehensions

This is similar code in C#

var nr = Range(1, 11).Where(it => it % 2 == 0).Select(it => Pow(it, 3));
WriteLine(Join(" ", nr));

8 – Sets

Same example

//this contains some duplicates
var languages = new[] { "C#", "Python", "VB", "Java", "C#", "Java", "C#" };
//more dense than Python
languages = new HashSet<string>(languages).ToArray();
//this will give: ['C#', 'Java', 'Python', 'VB']
WriteLine(Join(" ", languages));

Second example

//create two sets: Friends characters and large Antarctic ice shelves
var friends = new[] { "Rachel", "Phoebe", "Chandler", "Joey", "Monica", "Ross" };
var ice_shelves = new[] { "Ronnie-Filchner", "Ross", "McMurdo" };
// show the intersection (elements in both lists)
WriteLine(Join(" ", friends.Intersect(ice_shelves)));
//show the union (elements in either list)
WriteLine(Join(" ", friends.Union(ice_shelves)));
// show the friends who aren't ice shelves
WriteLine(Join(" ", friends.Except(ice_shelves)));
// elements in either set but not both -- more difficult
WriteLine(Join(" ", friends.Union(ice_shelves).Except(friends.Intersect(ice_shelves))));

9 – Working with files and folders

//# list of 3 people
var people = new[] { "Shadrach", "Meshach", "Abednego" };
//# write them to a file
File.WriteAllLines(@"C:\all\a.txt", people);
