C#语言：
C#是一种面向对象的编程语言，发音为C-Sharp。这种语言是由微软在 Anders Heijlberg 和他的团队的领导下开发的，用于与Java竞争。 C# 语言中总共使用了 86 个关键字。在 c# 中，指针仅在不安全模式下使用。
Python：
Python是一种多范式编程语言，例如面向对象编程和结构化编程等等。它是由Guido van Rossum在 1980 年代后期开发的。在Python 3.7 中总共使用了 33 个关键字。它不支持指针。它是一种动态类型语言，而 C# 是一种静态类型语言。这很容易学习。
Python和 C# 的区别
| S.NO. | C# | Python |
|---|---|---|
| 1. | C# is developed by Microsoft and is available free of cost, even for commercial purpose. The .NET ecosystem is completely open-source & is owned by .NET Foundation which is an independent organization. | Python is also an open-source platform and available free of cost, even for commercial purpose. |
| 2. | C# supports object oriented programming, structured programming, functional programming & many others. | While python supports multi-paradigm programming language such as OOPs and structured programming and many others. |
| 3. | C# requires .NET SDK & runtime. The .NET ecosystem offers interop with languages like F#, VB.NET, JavaScript, Python etc. | While it can also be integrated with .NET, C, JavaScript and java. |
| 4. | While primarily a compiled language, C# also supports interactive interpreter development environments using dotnet-interactive. You also also write C# in Jupyter notebooks. | Python supports interactive interpreter for writing programs. |
| 5. | C# multi-threading is quite easy due to the use of .NET Framework. | While in python, multi-threading needs many process due to Global interpreter lock. |
| 6. | There are 86 total keywords used in the C#. | While a total of 33 keywords are used in python 3.7 . |
| 7. | In C#, pointers are used only in unsafe mode. | Here, Python does not support pointers. |
| 8. | C# is a static-type language. | While python language is a dynamic-type language. |
| 9. | In C#, variable type must be declared before use. | While in python there is no need to declare variable type before use. |
| 10. | C# program files are saved by .cs extension. | Whereas python program files are saved by .py extension. |
