Functional Python Programming

Functional composition and currying

Some functional languages work by transforming a multiargument function syntax into a collection of single argument functions. This process is called currying—it's named after logician Haskell Curry, who developed the theory from earlier concepts.

Currying is a technique for transforming a multiargument function into higher order single argument functions. In the simple case, we have a function ; given two arguments x and y, this will return some resulting value, z. We can curry this into two functions: and . Given ...
