Presentation about nice functional programming things you can do with python. and some simple techniques you can use to do a good and functional design

1. Functional
Programming with
Python
Marcelo Cure

2. Functional Programming
Expressions over statements (instead of using a whole for, use
map/filter/reduce)
No side effect
Immutability
Simpler code
Expressiveness

3. Functional is stateless
Statefull Stateless

4. Don't iterate over lists

5. Use map/filter/reduce

6. A even better way

7. Another example with map

8. Another example with reduce

9. Lambdas

10. High Order Functions
Functions that manipulate functions
Send functions to functions allowing different behaviour

12. Function Composition

13. List Comprehentions
Comes from mathematics
{ x2 | x ∈ ℕ }
x * 2 given x is contained on the natural numbers

14. Immutability
● The same happens to other types: string, float, tuples, etc
● Lists and Dictionaries are mutable
● Objects are also mutable

15. Thanks
