EDIT: Let me try to clarify: I run this on a monday: yes, but this will update list for the time the script is running. WHen i run it the next day, i want it to be the same list that the update returned the previous day. If you don't want to self run the code you can use cron-job to do it for you.
Its sort of like this: So I want the update function to run every 5 days(I know how to do that) and the download function to run everyday.So how can i keep the list returned from update() static as the global list until it is updated again? Normal declaration of the variable will make it local. Just write the list to a file and access it read it from there later.The Public Health Agency of Canada recommends that travellers protect themselves from mosquito bites when travelling to areas where chikungunya may occur.Chikungunya occurs in Africa, the Americas, Asia, the Caribbean and the Pacific Islands.Since then, local transmission of the virus has spread to many countries in neighbouring regions.
Since 2014, there has been an increase in travel-related chikungunya cases reported in Canada.So, after sometime, pheromone will get evaporated (just like it does in natural process), so you have to simulate the evaporation by decreasing the pheromone content.Thanks, that makes sense, but the appendix left this bit out and confused me.Although caused by a different virus, the symptoms of chikungunya can appear very similar to those of dengue fever.There is no vaccine or medication that protects against chikungunya virus. Outbreaks of chikungunya have become increasingly frequent since local transmission was reported for the first time in the Caribbean in December 2013.Updated: August 26, 2016Chikungunya is a disease caused by the chikungunya virus which typically causes fever, along with an arthritis-like pain in the joints and a rash.
