Python All The Things!

We’re familiar with Python as a scripting language, as a web server language, as a teaching language, as a data analysis language, and as a teaching language. But is that the limit of where Python can be used? What is the future for Python on other platforms? Is the prospect of using Python on those platforms a novelty, or a viable way to fend off an existential threat to the language? And how does this threat intersect with other threats we have to our community, and to our industry?

9. How, and why?
10. How
11. What is Python?
12. Python is a language specification.
13. Python is a reference implementation.
14. CPython is a reference implementation.
15. Simplest approach: (Embedded) CPython
16. Unix & C
17. Porting CPython
18. A cavelcade of platforms... $ ls -d Lib/plat-* plat-aix3 plat-freebsd7 plat-next3 plat-aix4 plat-freebsd8 plat-os2emx plat-atheos plat-generic plat-riscos plat-beos5 plat-irix5 plat-sunos5 plat-darwin plat-irix6 plat-unixware7 plat-freebsd4 plat-linux2 plat-freebsd5 plat-mac plat-freebsd6 plat-netbsd1
19. Compiling the kernel
20. Cross-compiling the kernel
21. Compiling CPython
22. Embedding CPython
23. Accessing system libraries
24. ctypes & FFI
25. ctypes from ctypes import * libc = cdll.LoadLibrary("libc.so.6") libc.strchr.argtypes = [c_char_p, c_char] libc.strchr.restype = c_char_p >>> print(libc.strchr(b"abcdef", b"d")) 'def'
26. Where does this work?
27. Alas, I have no compiler...
28. Android, Java and Unix

38. Implementing a new Python Parser Compiler Eval loop Standard library
39. Batavia
40. Why not compile to Javascript?
41. Spot the difference var x = 10; function scope_test(y) { x = x * y; } scope_test(3) console.log('x = ' + x); x = 10 def scope_test(y): x = x * y scope_test(3) print('x = ', x)
42. Why not compile to Javascript?
43. The missing pieces
44. A different development cycle

69. Burnout
70. Don't assume resources are free
71. Relationship with money
72. A side effect: Enabling Diversity
73. The biggest challenges are non-technical
74. The biggest challenges are non-technical
75. The future
