i wondering how define inf , -inf int in python 2.7. tried , seems inf , -inf work float . a = float('-inf') # works b = float('inf') # works c = int('-inf') # compile error, valueerror: invalid literal int() base 10: 'inf' d = int('inf') # compile error, valueerror: invalid literal int() base 10: 'inf' to summarise said in comments there no way represent infinity integer in python. matches behaviour of many other languages. however, due python's dynamic typing system, can use float('inf') in place of integer, , behave expect. as far creating 'double' infinity, in python there 1 floating point type, called float , unlike other languages such java uses term float , double floating point numbers different precision. in python, floating point numbers use double-precision , act same doubles in java.

my situation this: have 2 models, model (as in car model) , engine . have models have more 1 engine (different model years came different engines), , have engines belong multiple different models (single engine reused across multiple models). forgive me being (very) new rails , activerecord, seems bit more complicated has_many , belongs_to . wrong. should note i'm using rails 5 . given have scaffolds/models in place , i'd rather not delete them, how write migration achieve above situation? need add respective models? use many-to-many relationship, make sure migration name contains jointable rails g migration createenginemodeljointable engines models engine class class engine < activerecord::base has_and_belongs_to_many :models end model class class model < activerecord::base has_and_belongs_to_many :engines end you can access by engines = model.engines models = engine.models

first off used programming java that's why using codename 1 develop mobile applications. however see code in android "format" interested on testing. know how set basic native interface codename 1 tutorial . for example, test snippet real time sound processing . involves initializing variable in android oncreate() method data available in method such am = (audiomanager) this.getsystemservice(context.audio_service); use of this has not same reference in codename 1 native interface. maybe don't have use oncreate() method (which be reached codename one ) not android guru (nor cn1 1 either!), don't know. consequently changes have make test native android code in codename 1 native interface ? maybe there methodology glad hear of. edit solved : code used in native interface implementation works here codename 1 native interface implementation of original android code . indeed android oncreate() method has not been used things initialized in have been ...
