blackjack - Python; NameError: name 'handsum' is not defined -


i coding basic blackjack game, , challenged myself make many functions possible, code looks this:

funca() funcb() funcc()

as opposed to:

funca() print("this") print("that") funcb()

here problem in code:

def playerturn():     global handsum     global cardone     global cardtwo     global dealersum     global upcard     global downcard     global bet     global newcard     global dealernewcard     str(handsum)     str(cardone)     str(cardtwo)     str(upcard)     str(money)     print("you lying at", handsum, "with a", cardone, 'and a', cardtwo       + '.', "the dealer has a", upcard, "facing up. have $" + money + '.')     int(handsum)     int(cardone)     str(cardtwo)     str(upcard)     str(money)     sleep(1.3)     bet=int(input('how bet? '))     sleep(1.3)     money-=bet     print("your bet $%s." %bet)     sleep(2.5)     playerinput=input(str(print('''would to:     hit (h)     stand (s)     double (d)     stick (sp)     enter letter answer: '''))).upper     sleep(1)     while true:         hit()         stick()         double()         quit()

and here's error once code reaches function:

traceback (most recent call last):   file "c:\users\owner\desktop\python\games\python 3.x\blackjack\blackjack.py",   line 20, in <module>     start()    file "c:\users\owner\desktop\python\games\python 3.x\blackjack\blackjack.py",   line 16, in start     intro()    file "c:\users\owner\desktop\python\games\python     3.x\blackjack\playerturns.py", line 242, in intro     playerturn()    file "c:\users\owner\desktop\python\games\python     3.x\blackjack\playerturns.py", line 188, in playerturn     str(handsum)  nameerror: name 'handsum' not defined

i using multiple python files (2) game.

in python, line like

str(handsum)

means calling function str argument handsum, , disgarding result. not, @ point in function, have variable called handsum in scope. due global handsum line (note capital s in sum) do have named, different variable in scope. meant refer variable, python case-sensitive.

however, don't know why want call str on variable , throw away return value. not declare handsum (you don't need declare python variables, created on assignment, , can bring them scope global keyword) nor convert handsum (if changed capitalisation) string (you need use return value of str(handsum) that), or indeed, @ all.

also, don't want use globals variables. pass them arguments function, or wrap them object. helps compartmentalise problems in future.

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...
