This document compares Python to C# and .NET, discussing key features of the Python language and how it compares to C# equivalents. It introduces Python basics in 10 minutes, covers how Python code is structured, and then explores popular C# features and their Python counterparts, such as objects, LINQ, properties, lambdas, debugging tools, and more. The document aims to help C# developers learn Python.

2. Agenda
●
Introduce the basics of the Python language
●
Review what is awesome about C# and .NET
●
Explore Python's version of each C# / .NET feature

3. The Python language in 10 minutes
●
●
●
●
●
●
●
Batteries included (large standard library)
High-level programming language
Interpreted (sometimes JIT compiled)
Object-oriented (especially Python 3)
Strongly-typed with dynamic semantics
Syntax emphasizes readability
Supports modules and packages

4. The ‘shape’ of a Python program
●
Python defines code blocks
(known as suites in Python)
using whitespace and colons.

6. What's awesome about C# and .NET?
System.Object: Everything is an object.
LINQ
IEnumerable + foreach loops
Visual Studio / IDEs
Class properties ( int Age {get; set;} )
Side-by-side execution (isolation)
Anonymous types
Iterator methods / yield return
Add reference
Anonymous methods / lambdas / closures
NuGET package management
Base class libraries
Entity Framework / ORMs
JIT compilation
Great debugging tools
Resharper and IDE plugins
