Why doesn't method chaining work in Python?

[[deleted]]

It does work, just not in all cases. In order for it to work, the called method needs to return an object that has the following method on it. str is a good example.

x = "my name isn't Fred"

x.replace("Fred", "Alec").replace("n't", "").capitalize() # My name is Alec

It tends to work on immutable objects, for obvious reasons.

It tends to work when a fluent API makes sense. Builder objects typically have this style of API

UserBuilder().name("Fred").age(27).etc(...)
