[ad_1] use list comprehension in python l = [3, 11, 4, 9, 1, 23, 5, 11] indexes = [index for index in range(len(l)) if l[index] == 11] output: [1, 7] use numpy for finding the matching indices. import numpy as np l = [3, 11, 4, 9, 1, 23, 5, 11] np_array = np.array(l) item_index … Read more
[ad_1] I don’t know what you are trying to do, but *= doesn’t appear to do what you think it does. *= is an assignment operator. It evaluates its left-hand side and its right-hand side, multiplies them together, and assigns the result to the result of its left-hand side. The result of a + b … Read more
[ad_1] The error is that you are re-using the teleportation_start_position variable. teleportation_start_position = min(teleportation_start_position, teleportation_end_position); Before this line the state of your program is: teleportation_start_position = 8 teleportation_end_position = 2 But after, it is: teleportation_start_position = 2 teleportation_end_position = 2 So in the next line you are doing: teleportation_end_position = max(teleportation_start_position, teleportation_end_position); // teleportation_end_position = … Read more
[ad_1] The distinct keyword is supposed to be outside like below, SELECT DISTINCT column1, column2, … FROM table_name; ? Also, you are trying to sum few things, It should be something like below, SELECT UID, COUNT(UID) AS TOTAL, SUM(CASE WHEN SYSTEM = ‘Android’ THEN 1 ELSE 0 END) AS A, SUM(CASE WHEN SYSTEM = ‘IOS’ … Read more
[ad_1] You can implement a custom dict wrapper (either a subclass of dict or something that contains a dict) and implement __getattr__ (or __getattribute__) to return data from the dict. class DictObject(object): def __init__(self, data): self.mydict = data def __getattr__(self, attr): if attr in self.mydict: return self.mydict[attr] return super(self, DictObject).__getattr__(attr) [ad_2] solved Access dict via … Read more

The line of code containing srv.ListenAndServe() is a blocking line of code causing the log after this line of code not to happen. In my original code I demonstrated in my earlier blog I had this log in front of … Read more
[ad_1] Use the following: An onEdit trigger to check when someone has updated a cell padStart() to add the leading zeros replace() the first 4 zeros with “CSC1” (since only the first occurrence will be replaced if passing a string instead of regular expression) setValue() to update the edited cell function onEdit(e) { if (e.range.columnStart … Read more
