python - I would call this advanced tuple manipulation? -


i'm trying take list of tuples contain name of individual functions , arguments , instantiate them..this used multi-threading application.

import pandas pd  df = pd.dataframe()  def func1(df,arg2,arg3):     print 'func1'     print type(df)     print arg2,arg4  def func2(arg1,df,arg3,arg4):     print 'func2'     print arg1     print type(df)     print arg3,arg4  list_of_func_tups = [(func1,df,'two','three'),(func2,'one',df,'three','four')]  tup in list_of_func_tups:     f = tup[0]     args = tup[1:]      results = f(args)

but problem args still seen tuple, hence, error stating 1 argument given.

typeerror: func1() takes 3 arguments (1 given)

is there way can somehow args seen respective individual arguments? maybe type of loop or something? anythin?

what looking way feed tuple positional arguments. can using leading asterisk (*):

result = f(*args)

this documented in documentation of function calls:

if syntax *expression appears in function call, expression must evaluate iterable. elements iterable treated if additional positional arguments; if there positional arguments x1,..., xn, , expression evaluates sequence y1, ..., ym, equivalent call m+n positional arguments x1, ..., xn, y1, ..., ym.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
