loops

问题 I want to be able to have two while True loops running at the same time. Would this be possible? I am extremely new to Python, so I do not know how to get round this problem. This is the code I made: import time def infiniteLoop(): while True: print('Loop 1') time.sleep(1) infiniteLoop() while True: print('Loop 2') time.sleep(1) Right now, it just prints a 'Loop 1' Thanks in advance 回答1: To run both loops at once, you either need to use two threads or interleave the loops together. Method 1:

问题 I have an expression qbinom(0.05, n, .47) - 1 and I want to create a loop which iterates this expression over n for n = (20,200). For each iteration of this loop, this function will produce a number. I want to take the maximum of the 180 numbers it will produce. So, something like. for (n in 20:200) { max(qbinom(0.05, n, .47)-1) But I'm not sure how exactly to do this. Thanks! 回答1: First, I will show you how to do this with a loop. n <- 20:200 MAX = -Inf ## initialize maximum for (i in 1

问题 I am using the R programming language. I want to learn how to measure and plot the run time of difference procedures as the size of the data increases. I found a previous stackoverflow post that answers a similar question: Plot the run time of three functions It seems that the "microbenchmark" library in R should be able to accomplish this task. Suppose I simulate the following data: #load libraries library(microbenchmark) library(dplyr) library(ggplot2) library(Rtsne) library(cluster)

问题 I have 14 different XML files like this and I'm trying to get ActionUnit Number values (ex. 45 and 5). I need to do it for the other 13 XML files too with a loop. After that, I need to create subfolders for each value that I extracted. I tried a code for value extraction but I get none as a result; import xml.etree.cElementTree as ET tree= ET.ElementTree(file=r'C:\Users\LME_s\Desktop\python quiz\Sessions\1\S001-001-oao_aucs.xml') root= tree.getroot() for chld in root: print (chld.get(

问题 I'm trying to make a circlular bar progress using html canvas and javascript and i've suceed until I've add a loop with setInterval, since that I'm stuck... I tried to target the problem putting console.log() in all the elements I use to do the loop, but I can't get through why my loop is working in the console but the cirlce doesn't appear. Can anyone help me. I will be very grateful. Thank you in advance. here is my code : class GreyCircle { constructor(x, y, radius) { this.posX = x; this

问题 My question is related to the previous question: How to parse several attributes of website with same class name in python? I want to include the parsing within a loop over cap and append the resulting parsed text in a vector or data set at the end of the loop and then continue at the top. My loop now looks like this: driver = webdriver.Chrome('pathtoChrome/chromedriver.exe') caps = ['11100'] for cap in caps: driver.get("https://www.conad.it/") WebDriverWait(driver, 20).until(EC.element_to_be
