Python vs C#
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.
I want to think about how to modelate a CallCenter waiting for phones – Stack or Queue ?

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);
