for-loop

问题 I would like to make this simplified so that I can control how many nested for loops there are. Essentially this would be 3 for d1 in ['left','right','up','down']: for d2 in CreateDirectionList(d1): for d3 in CreateDirectionList(d2): #Do something with list [d1, d2, d3] return False and 4 would be for d1 in ['left','right','up','down']: for d2 in CreateDirectionList(d1): for d3 in CreateDirectionList(d2): for d4 in CreateDirectionList(d3): #Do something with list [d1, d2, d3, d4] return False

问题 I would love to simplify my code, with better utilisation of for loop indexes. The goal is to change out all UP once for new UP once, which means take down each UP one and bring it up again. There should always be one in UP state while this process takes place, so I need to cover the following scenarios: up - up == delete -> create -> delete -> create down - down == delete -> create -> delete -> create up - down == delete -> create -> delete -> create down - up == delete -> create -> delete -

问题 Please correct me if there are somethings unclear in this question. I have two matrices pop , and ben of 3 dimensions. Call these dimensions as c,t,w . I want to repeat the exact same process I describe below for all of the c dimensions, without using a for loop as that is slow. For the discussion below, fix a value of the dimension c , to explain my thinking, later I will give a MWE. So when c is fixed I have a 2D matrix with dimension t,w . Now I repeat the entire process (coming below!)

问题 I have an example dataset, garden , as shown below. The real thing is thousands of rows. I also have an example list. productFruit . I want to know the calories of every fruit , considering the usage reported in garden . I basically want to loop through all the rows in my table, check if the usage is recorded in the productFruit list and the return either the calories or one of the following error messages: "usage out of scope" if no usage has been found in the productFruit list "fruit out of

问题 I want all ClickableSpans to have toasts show their own text. But whatever I write in Toast in onClick in for loop, all ClickableSpans show same Toast output. Briefly, I just want ClickableSpans to show different Toasts in for loop. How can I do it? I want all words have clickable. And when all words are clicked, they do different thing. Thank you for your help. public class MainActivity extends AppCompatActivity { private String[] textArray; private String text = "1981 senesinde kuantum
