Retrieving Python Keywords

[candide]

Python is very good at introspection, so I was wondering if Python (2.7)
provides any feature to retrieve the list of its keywords (and, as,
assert, break, ...).

Yes. (Look in the manuals, or try the obvious imports ;-)

import keyword

Actually this is all it takes:
import keywords
print keywords.kwlist

--jac

so I considered first it was a joke ! In fact the import doesn't
need plural, and... Python is very very introspective


Thanks and thanks to Steven too.

I did : my main reference book is the Martelli's /Python in a Nutshell/
and the index doesn't refer to the keyword import

The only obvious I saw was sys module.

You should only use that as a supplement.

and the index doesn't refer to the keyword import

and now you know why ;-).

I meant the fine, heavily edited and constantly improved by 20+ people
manuals that come with Python. The Global Module Index has one entry
under K -- the keyword module. The General Index has multiple entries
for 'keyword', including 'keyword(module)'.

I meant, 'import keyword' or 'import keywords'.
Sorry, I guess perhaps not so obvious if one is not used to Python's
extreme introspection features.

The MAIN reference for language specific details should be the
language reference manual that should have come with the installation.
Nutshell mostly expands on the library features.

Section 2.3.1 of the language reference manual is titled: Keywords

['and', 'as', 'assert', 'break', 'class', 'continue', 'def', 'del',
'elif', 'else', 'except', 'exec', 'finally', 'for', 'from', 'global',
'if', 'import', 'in', 'is', 'lambda', 'not', 'or', 'pass', 'print',
'raise', 'return', 'try', 'while', 'with', 'yield']
