[Solved] Why is tabbed space width not constant

[ad_1] It works as intended. The original purpose of tab is printing tables. Rather than expanding to exactly N spaces (N being tab width, normally 4 or 8), it sets X coordinate of the cursor to the next multiple of N. Consider this example: #include <stdio.h> int main() { for (int i = 0; i … Read more

[Solved] How does UserPassesTestMixin in django work?

[ad_1] The user id coming from the user in the request object is an integer, while the self.kwargs[‘pk’] is a string unless you do something about it.

Here’s how typecasting should look void typecasting(unsigned char test[SIZE], int array[SIZE]) { for (int i = 0; i < SIZE; ++i) array[i] = test[i]; } Your code might be suitable if you were converting from a C string, i.e. if your original test array was char test[] = “34,201,190,154,8,194,2,6,114,88,45,76,123,87,25,23,…”; … Read more

This means the pre-increment operator ++var can be simulated in Python by var := var + 1. This increments … Read more

[Solved] What does subset(df, !duplicated(x)) do?

[ad_1] The duplicated function traverses its argument(s) sequentially and returns TRUE if there has been a prior value identical to the current value. It is a generic function, so it has a default definition (for vectors) but also a definition for other classes, such as objects of the data.frame class. The subset function treats expressions … Read more

[Solved] Why count yields different results using group by vs where?

[ad_1] Strings like ‘2018-01-31’ are considered ‘2018-01-31 00:00:00’ when used with datetime and timestamp values; so basically, you are not counting the last day of the time span with the latter query. If you want to do the latter, it can be simpler to do: where datehour >= ‘2018-01-01’ and datehour < ‘2018-02-01’ 4 [ad_2] … Read more
