Knowing length of input argument of a function in python -

-

let's have function:

def func(x, p): return p[0] * x ** 2 + p[1] * x + p[2]

and now, can information function using inspect:

import inspect args, varargs, varkw, defaults = inspect.getargspec(func)

but know have 2 arguments, instead of information on each argument (whether it's scalar or else).

just making sure - theoretically, there way can know minimum length of tuple p used in function?

thank you!

the answer no.

firstly can't assume type (let alone size of argument).

secondly, there no way tell length, because it's supposed arbitrary , function may nothing input @ all.

if want similar, try use *l variable-length arguments. there **d arbitrary map (named arguments).

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
