loops

问题 I'm making a code so that when a user clicks on the window, it will draw the shape based on their input of choice. I'm having trouble on where I should assign the window and turtle correctly and how to assign to a function a way to quit the window its currently on. Is there any way for me to end a mainloop() so that the user goes back to the main menu after clicking and making as many of their chosen shapes (given that each time they do choose an option, the window resets to a blank state)?

问题 As the title says I'm trying to read a JSON file that looks like the following: { "response": { "current_time": 1490040712, "success": 1, "items": { "AK-47 | Black Laminate (Minimal Wear)": { "last_updated": 1490025658, "value": 985, "quantity": 124 }, "AK-47 | Aquamarine Revenge (Field-Tested)": { "last_updated": 1490025658, "value": 1775, "quantity": 127 }, "AK-47 | Black Laminate (Field-Tested)": { "last_updated": 1490025658, "value": 890, "quantity": 130 }, "AK-47 | Aquamarine Revenge

问题 I have this code at the moment that works and calculates the interest of an account depending on the conditions set. However I now need to code a function called CalcInterest() which takes as its only parameter - an Account, - and return the Interest calculated. #include <iostream> using namespace std; int main() { int AccountNumber[8] = { 1001, 7940, 4382, 2651, 3020, 7168, 6245, 9342 }; float Balance[8] = { 4254.40, 27006.25, 123.50, 85326.92, 657.0, 7423.34, 4.99, 107864.44 }; int

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I have noticed similar repetition and trying to work around using a single for loop for this if I can to minimize the code length: I wouldn't need to use a switch case if I can form a loop instead? $returnNo variable starts at 5, each case multiplied by 2 then minus 1. where

问题 I have a function "zoom" which takes the following format: zoom( [a,b,c,d....], [a,b,c,d...] ); I also have a for loop which gets me the values that need to go into the zoom array: ABC.getAggregation("V")[0].getItems().forEach( function (item) { var a = item.getPosition().split(";")[0]; var b = item.getPosition().split(";")[1]; ABC.zoom( [...], [...] ); }); How can I add variables a and b into the arrays of function zoom? All variable a's must go into the first array and all variables b must

问题 When I run the code with the while True: loop included within the root.mainloop() it is making my GUI lag heavily and the code does not run as smoothly as I would like. I am wondering how I make my code run smooth and without lag. for the purpose of this test I have commented out large sections of the code that only work when it is hooked up to my raspberry pi. Thank you in advance for your help. import os import glob import time #import RPi.GPIO as GPIO from datetime import datetime from

问题 I am calling a for loop multiple times. I would like to save a single setTimeout for each index. The idea is to use the loop's index as setTimeout's array index, but setTimeout returns an incremental ID number, I would like to reset it, or override to take control of the returning ID, so I can identify each timeout with a given index, always within the range of loop's index that is executed over and over again. Being able to use clearTimeout later on with a specific index. var timeouts = [];

问题 I am trying to build a data frame where I have a series of columns which contain a random assignment of another column. The data has some structure which needs to be maintained. Namely I want to randomise the assignment of L many time over, while maintaining the structure in V . I want to take a dataframe that looks like this; L B V A 1 1 1 2 10.9 2 1 1 2 6.5 3 1 1 2 8.6 4 1 1 3 11.1 5 1 1 4 13.1 6 1 1 6 11.5 And create this; ID L B V A R1 R2 R3 R4 R5 1 1_1_2 1 1 2 10.9 27 20 19 6 26 2 1_1_2

问题 I am trying to write a code that identifies the length of a repeating time sequence (in seconds) in R and subsets each sequence into its own data frame for curve fitting and analysis. Each sequence is a time series of sensor voltage output and has to be analyzed separately. My code seems clunky, but it works as it is written here. I am trying to figure out if there was a package or easy step that I was missing for doing this more elegantly. The seconds are decimal seconds and the data could
