O que Python tem para atrair mais de 35 mil inscritos num curso? Python para Zumbis é o primeiro MOOC (Massive Open Online Course) em português e visa ensinar programação para iniciantes. É uma iniciativa de três pessoas que não contaram com nenhum recurso financeiro, além do próprio investimento pessoal. Todo material é licenciado como Creative Commons Share Alike, permitindo a docentes de outras instituições fazerem reuso dos slides, listas de exercícios, etc. Nesta palestra você não verá nada de teoria, veremos os códigos que mais fizeram a alegria zumbi: hackear dados públicos para calcular os gastos da Copa do Mundo, games clássicos diretamente no navegador, metaprogramação 42 (resposta para tudo), pegar os resultados dos jogos da copa com poucas linhas e muito mais. Se quiser acompanhar, deixe Python 3 e Pygame instalados em seu computador para acompanhar com links do github. O autor deu 40 palestras e minicursos em 2014 sobre Python, devido à divulgação obtida pelo Python para Zumbis, no Brasil e pelo mundo afora.

1. Python, the next
Brazilian generation

2. Why Python?

introductory-teaching-language-at-top-us-universities/fulltext

3. Why Python?
"Results show that many aspects of traditional C-
style syntax, while it has influenced a generation of
programmers, exhibits problems in terms of
usability for novices".
"Perl and Java did not accuracy rates significantly
higher than a language with randomly generated
keywords"
Andreas Stefik and Susanna Siebert: "An Empirical Investigation into
Programming Language Syntax." ACM Transactions on Computing
Education, 13(4), Nov. 2013.

4. The most common fault in computer classes is to
emphasize the rules of specific programming
languages, instead of to emphasize the algorithms
that are being expressed in those languages. D. Knuth
interview at People of ACM, June, 2014.

5. http://www.python.org/psf/diversity/
“We want our community to be more
diverse: whoever you are, and
whatever our background, we
welcome you”

6. Diversity
Diversity in Python Community is real
2014: 1/3 talks PyCon by women
2015: 1/3 talks PyCon by women
2015: 1/3 talks DjangoCon by women
2015: 7 women, 4 men (newly elected
PSF board)

7. http://pyladies.com
We Love Python

8. Each week on our blog we try to introduce two badass
ladies who use Python or Django to highlight their work.
What about you?

9. Goal: 25% non American 2015
We Love Python

11. A good sword just does not make a good
samurai, not just use Python

12. Python for Zombies

13. Summary
in 18 months
3 folks + zero budget =
30.000 enrollments
of comparison: one university professor reaches 3000 students throughout his career

14. Summary
Some girls that are former students have even
created the first PyLadies chapters in Brazil.

15. Last year: 40 talks and workshops in 9 countries

16. I love teaching

17. Goal
Teaching programming for everybody, for
free, in portuguese (only 5% of Brazilian
people are fluent in English1)
1. IBOPE (2012)

24. Community initiative
Not of my university

25. Cronology
• November 2012: “We need a MOOC to teach
Python” Marcel Caraciolo (president of Python
Brazil Association)
• My answer: “Cool, it will be ready in two years”
• July 2013: “Next month we will have the first
MOOC for teaching programming in Portuguese.
This is the website for pre-registration…”.
Marcel's announcement at Campus Party Brazil.

26. My first reaction
Because I had nothing ready

27. But we did it
One month to:
1.Design the entire course
2.Get the first week videos recorded
PS: We took advantage of a platform that already existed

28. Nexts weeks
I recorded the lessons at:
1.Fast food restaurants, airports, FATEC
classrooms
2.Travels to conferences
PS: theBoom Noise Canceling Headset is really useful

29. Python 3
• Convenient to use accents in foreign languages
– Ex.: opção = 42
• More natural division
– 1 / 2 results 0.5

30. Small 4min videos without quizzes

31. A huge compilation of exercises
• CodingBat
• Google Python Class
• Google Developer Day
• Cracking Code Interview
• Facebook Hackaton
• Edx MIT
• IME – USP

32. 12 years old girls code
To promote diversity

33. 30.000 enrolled in one year and half

34. overcomed with good humor
Some availability problems

35. TWD Portugal Fanpage

36. Some data
• Only three people:
– Fernando Masanori (videos)
– Gileno Filho (Django Dev)
– Marcel Caraciolo (Data Scientist)
• Zero budget: no grants, no investments received, no
crowdfunding
• With the collaboration of the whole Brazilian Python
Community
• 30.000 enrollments in one year and half of activity
• Course completion: 8.91%

37. Former students: PyLadies Brazil

38. First PyLadies Event (100+) 80 women

binary integer between 0 and 2 ** n-1, inclusive. These binaries will be drawn in descending
order according to the number of existing 1s. If there is a tie choose the lowest numerical
value. Return the k-th element from the selected list. Eg n = 3 and k = 5 ['0 b111 ', '0 b11', '0
B101 ', '0 b110', '0 b1 ', '0 b10', '0 b100 ', '0 b0'] fifth element '0 b1 '
