I don't know about any other way, but here's a really REALLY stupid
method. For every possible alphabetic string, attempt to eval() it; if
you get NameError or no error at all, then it's not a keyword.
SyntaxError means it's a keyword.
>>> eval("foo")
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
eval("foo")
File "<string>", line 1, in <module>
NameError: name 'foo' is not defined
>>> eval("lambda")
Traceback (most recent call last):
File "<pyshell#7>", line 1, in <module>
eval("lambda")
File "<string>", line 1
lambda
^
SyntaxError: unexpected EOF while parsing
>>> eval("eval")
<built-in function eval>
Yes, it's stupid. But I'm feeling rather mischievous today. :)
