[ad_1] You iterate over an array which you grow as you iterate over it. First values is [2,3,4] then after the first iteration, values is [2, 3, 4, [2, 255, 255]] then [2, 3, 4, [2, 255, 255], [3, 255, 255]] etc. You should print along the iteration to understand it better.

[ad_1] It seems parsedatetime module that should parse human-readable date/time text works in this case: #!/usr/bin/env python from datetime import datetime import parsedatetime as pdt # $ pip install parsedatetime cal = pdt.Calendar() print(datetime.now()) for time_str in [“8 seconds ago”, “5 minutes ago”, “11 hours ago”, “11:34 AM yesterday”]: dt, flags = cal.parseDT(time_str) assert flags … Read more
[ad_1] Any JS problem relating to this is likely due to the way the function using this is called. Storing a reference to this in your that variable should let you reference it from within your nested functions, exactly the way you are doing it already – assuming that qwerty() is called in a way … Read more
[ad_1] We have a similar system on our site, where users can bookmark pages to a planner/wishlist function.

[ad_1] Preface: Given your “console application” doesn’t involve forking any processes or performing any “actual” I/O, you may want to redesign your application to use the TextField and TextArea directly, or at least more directly than you’re currently trying to do.

[ad_1] If you need to be able to reference lil_patate elsewhere in your code then you can’t make this factorisation at all. If you don’t need to refer to lil_patate elsewhere then get rid of it and initialise patate directly from q_nutrients: string patate(to_string(q_nutriments)); However, while this may improve the readability of the code, it … Read more
