Hi,
for a school project I'm trying to analyze some python modules. I just
struggeld over a little detail I cannot solve:
shortened example of walking trough an AST with my own visitor:
class MyVisitor:
def visitFunction(s elf, t):
# Here I do not know know how to associate the default values
in t.defaults
# with the arguments in t.argnames
params = '???' # howto join the right args with their
default???
print "def %s(%s)" % (t.name, params)
fname = 'test.py'
ast = compiler.parseF ile(fname)
compiler.walk(a st, MyVisitor())
I can only get a list with the arguments or the defaults. The following
examples would return the same:
def foo(x, y=True)
def foo(x=True, y)
Anyone an idea?
Thanks,

the latter is a syntax error.

the defaults array contains the defaults for the len(defaults) last arguments.

And again the own stupidity: I didn't check all my testcases for syntax
errors.
Thanks a lot,

I've tried everything; and I can't seem to get past this VERY
(seemingly) simply problem.
I want to work with an array variable within a function(s).
I can't get it to work; if I:
1) global $arr=array(); (syntax err)
2) global $arr; in "main", the var isn't global
3) global $arr; in function, the array is cleared each time

Hi,
I know that PLY lex is able to do line counting. I am wondering if there
is a way to count the number of each keywords (tokens) in a given file?
For example, how many IF tokens etc?
Thanks

Time for another random syntax idea. . .
So, I was tinkering in the interactive interpreter, and came up with the
following one-size-fits-most default argument hack:

Is there a simple way to get a dictionary of
argument names and their default values for
a method or function? I came up with one solution, but
I feel like Python must have a simpler way.
Python provide a way to get a sequence of
argument names and a different way to get a
sequence of default argument values. Since
default values have to come at the end of an
argument list you can match up the values in the

hi everyone,
I'm googeling since some time, but can't find an answer - maybe because
the answer is 'No!'.
Can I call a function in python inline, so that the python byte compiler
does actually call the function, but sort of inserts it where the inline
call is made? Therefore avoiding the function all overhead.
Thanks and cheers,

I'm building a parser in Python, and while pondering on the design of

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
