what's wrong with my lua code? - 


local consumer = coroutine.create(function(i)    while true     = - 1     print('consumer: ' .. i)     coroutine.yield(i)    end end)  local producer = coroutine.create(function()    while true      = or 0      = + 1      print('producer: ' .. i)      status, value = coroutine.resume(consumer, i)      = value    end end)  coroutine.resume(producer)

the console print

but it's wrong, right print should this: 0 1 0 1 01

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.
