Web backends development using Python
This document summarizes and compares several popular Python web frameworks - Django, Flask, Tornado, and aiohttp. Django is the most popular full-stack framework that provides an ORM, template engine, tests, and other features out of the box. Flask is a microframework that requires extensions for features like SQLAlchemy for ORM and Jinja2 for templating. Tornado is both an asynchronous network library and web framework that has been supporting asynchronous features since Python 2. Aiohttp is an HTTP client/server library for asyncio that can be used to build asynchronous web applications and servers in Python 3. The document discusses when each framework would be suitable depending on requirements like asynchronous features or database usage.

- 7. 7
- 9. used flask 9
- 10. used tornado 10
- 11. tried aiohttp 11
- 12. django, flask, tornado and aiohttp 12
- 13. django Most popular Python web framework Full stack web framework 13
- 14. Most popular 14
- 16. = has almost everything 16
- 17. Full stack ORM Template Engine Tests And more... 17
- 18. ORM 18
- 19. ORM 19
- 20. ORM >>> Foo.objects.filter(bar__contains=’1’) SELECT "world_foo"."id", "world_foo"."bar", "world_foo"."created_at", "world_foo"."modified_at" FROM "world_foo" WHERE "world_foo"."bar" LIKE ‘%1%’ ESCAPE '' LIMIT 21 20
- 23. template engine a lot of useful builtin tags intcomma autoescape linebreaks also can make custom tags 23
- 25. And more... django admin useful middlewares session management protection against csrf attack migration And more... in djangoproject.com 25
- 26. = django has super productivity 26
- 27. In my case 27
- 28. I use django when need web pages(html). 28
- 29. django was born for web sites. 29
- 30. flask Very popluar Python web framework in developers Microframework 30
- 31. Very popular 31
- 33. Werkzeug 33
- 34. = WSGI Utility Library 34
- 35. = HTTP Server using Python (PEP333) 35
- 36. = URL Route and Response 36
- 37. jinja2 37
- 41. = has almost nothing 41
- 42. = has free 42
- 44. SQLAlchemy (Flask-SQLAlchemy) ORM Alembic (Flask-Alembic) Migration Flask-Login session management useful extensions 44
- 45. In my case 45
- 46. I use flask in anytime. 46
- 48. tornado Web framework Asynchronous network library 48
- 49. Web framework 49
- 51. = has template engine 51
- 53. but, It hasn’t enough bulitin tags. 53
- 55. = tornado’s key feature 55
- 57. has asyncio 57
- 58. = has async features 58
- 59. But, tornado has that since Python2. 59
- 60. = has good performance since Python2 60
- 61. = can code socket and more 61
- 62. = even as a container 62
- 63. In my case 63
- 64. I use tornado when build websocket and use nosql. 64
- 65. Async is tornado’s key feature. 65
- 66. Not use async with rdbms. 66
- 67. or as a wsgi container 67
- 68. aiohttp HTTP Client / Server for asyncio 68
- 70. = HTTP Server for Python3. 70
- 71. = like a werkzeug in flask. 71
- 72. = URL Route and Response 72
- 73. In my case 73
- 74. I use aiohttp when build websocket or try experiment. 74
- 75. There are some async rdbms driver for Python3. 75
- 76. I just started web framework based on aiohttp. 76
- 78. In Real World 78
- 79. Yes, Python is slow. 79
- 82. ‘’.join((‘a’, ‘b’)) > ‘a’ + ‘b’ 82
- 85. use gevent 85
- 86. use PyPy 86
- 87. normal stack 87
- 88. django / flask 88 uWSGI / gunicron nginx / apache MySQL / PostgreSQL / Oracle / MSSQL Cache (redis / memcached / rabbitmq) reverse proxy
- 89. Thanks a lot!
