python: simulation termination -


I had just a quick question for the following simulation, if an event occurs, say birth it automatically time_elapsed Will it increase, or will it go to death and check death and will do it? 

  while time_elapsed & lt; End_time: event = birth () + death () + transition () like = random. Random () * event option - = birth () time_elapsed + = random.expovariate (event) if option & lt; 0: do_birth () likes release - = death () if preferred & lt; 0: do_death () Continue option - = total_infection_rate () if the choice is & lt; 0: do_infection () issued    
 
 
 In your code above, it will conduct all conditional checks Until anyone evaluates for  true , if the statements are to do so, then it will execute the code in that block and then  continue  will return to the beginning of the loop, All other  if  statements (regardless of whether they can be  true  or not). If you want to do only one case, then you will:  
  if the number> = 0: Print ('number is positive') and: print ('number is negative'), dragon  if number & gt; = 0  will evaluate the block and if it is  true , it will print  'the number is positive'  and then the  else  statement Except if  if number> = 0  Block is evaluated on  incorrect , then the dragon will execute the code in the  else  block and then proceed.  
 For more detailed cases, you can also use  elif  Here is a common example:  
  if number & gt; 0: Print ('Number is Positive') Elif Number & lt; 0: print ('number is negative') and: print ('number is 0')   
 It follows the same logic. Python will start from the top of the block and will not evaluate each condition in the  if  /  elif  block unless the condition for any condition  true  Does not, at which point it will execute the code under the block and then leave all other conditional statements in that group.

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.

I use Django 1.6.5 with settings in my program txsite: DEBUG = true I set the lie to debug, but when I get the runner , I get the following error: CommandError: You have to set the settings.
