But, according to its documentation, NumPy uses it. There is another use for ellipsis, which has nothing to do with slices. It can be used in intra-thread communication with queues, as a mark that signals "Done". Let us understand with the help of an example, ...
if (i == 5) { break; // Exit the loop when i equals 5 } printf("%d ", i); } return 0; } In this example, the “for” loop iterates from 1 to 10. However, when the value of “i” becomes 5, the “break” statement is encountered, and the loop is terminated prematurely...
