do know how can write code in python including function takes list , find out if arithmetic or geometric? wrote code boolean , doesn't arithmetic or geometric , has output. l=[int(x) x in input("please enter list:").split()] def arithemetic(l): i=1 if(l[0]+l[i]==l[i+1]): return true i+=1 def geometric(l): i=1 if(l[0]*l[i]==l[i+1]): return true i+=1 def isarithemeticorgeometric(l): if(arithemetic(l)): print(arithemetic(l)) elif(geometric(l)): print(geometric(l)) print(isarithemeticorgeometric(l)) there few mistakes here, try go on them 1 one asking list l=[int(x) x in input("please enter list:").split()] this throw valueerror when gets fed non-numeric type. round float int problem 1 can solve surrounding while loop , try-catch block while true: try: l=[int(x) x in input("please enter list:").split()] break except valueerror: pass the problem int can solve

i interested in performance of pyomo generate or model huge number of constraints , variables (about 10e6). using gams launch optimizations use different python features , therefore use pyomo generate model. i made tests , apparently when write model, python methods used define constraints called each time constraint instanciated. before going further in implementation, know if there exists way create directly block of constraints based on numpy array data ? point of view, constructing constraints block may more efficient large models. do think possible obtain performance comparable gams or other aml languages pyomo or other python modelling library ? thanks in advance ! while can use numpy data when creating pyomo constraints, cannot create blocks of constraints in single numpy-style command pyomo. fow it's worth, don't believe can in languages ampl or gams, either. while pyomo may support users defining constraints using matrix , vector operations, not th

i have code , when executes, throws nullreferenceexception , saying: object reference not set instance of object. what mean, , can fix error? what cause? bottom line you trying use null (or nothing in vb.net). means either set null , or never set @ all. like else, null gets passed around. if null in method "a", method "b" passed null to method "a". the rest of article goes more detail , shows mistakes many programmers make can lead nullreferenceexception . more specifically the runtime throwing nullreferenceexception always means same thing: trying use reference, , reference not initialized (or once initialized, no longer initialized). this means reference null , , cannot access members (such methods) through null reference. simplest case: string foo = null; foo.toupper(); this throw nullreferenceexception @ second line because can't call instance method toupper() on string reference pointing null .
