Method Chaining Classes in Python

From the creator

Method chaining, cascading, or the "Fluent API". This style of programming involves having methods of a class return the object they operate on in order to allow a subsequent method call. This is used to chain mutations of an instance or can also be used creating copies for immutable objects. This is not the most common style of programming, but it does have some niche uses, which we explore in this video. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode SQLAlchemy: https://docs.sqlalchemy.org/en/14/orm/quickstart.html pyjanitor: https://pyjanitor-devs.github.io/pyjanitor/ SUPPORT ME ⭐ --------------------------------------------------- Patreon: https://patreon.com/mCoding Paypal: https://www.paypal.com/donate/?hosted_button_id=VJY5SLZ8BJHEE Other donations: https://mcoding.io/donate Top patrons and donors: Jameson, Laura M, Dragos C, Vahnekie, John Martin, Casey G BE ACTIVE IN MY COMMUNITY 😄 --------------------------------------------------- Discord: https://discord.gg/Ye9yJtZQuN Github: https://github.com/mCodingLLC/ Reddit: https://www.reddit.com/r/mCoding/ Facebook: https://www.facebook.com/james.mcoding CHAPTERS --------------------------------------------------- 0:00 Intro 0:12 Basic example 1:20 Immutable examples 2:21 SQLAlchemy select 3:18 Pyjanitor example
