问题 Given a fix path and a very limited directories from year. I'm trying to obtain each combination of path between this initial combination ( fixPath - year ) and the different, non-fixed and non-equally quantity , subdirectories contained in each combination of fixPath - year fixPath <- "C:/Users/calcazar/Desktop/example" year <- 2008:2010 pathVector <- paste(fixPath, year, sep = "/") pathVector [1] "C:/Users/calcazar/Desktop/example/2008" "C:/Users/calcazar/Desktop/example/2009" [3] "C:/Users

问题 I have a fairly basic question here. I want to find if two lines on a 1-D plane intersect. I know of two simple ways to solve this, but I wanted to know if Python has a more elegant way to solve this? Ex: x = [1, 10] # 1 = begin, 10 = end y = [15, 20] z = [5, 12] #Method 1: Works. Is quick. Lots of typing. def is_intersect_1(a, b): bool_check = False if a[0] <= b[0] <= a[1] or \ a[0] <= b[1] <= a[1] or \ b[0] <= a[0] <= b[1] or \ b[0] <= a[1] <= b[1]: bool_check = True return bool_check is

问题 I am trying to webscrape some parts of this page: https://markets.businessinsider.com/stocks/bp-stock using BeautifulSoup to search for some text contained in h2 title of tables when i do: data_table = soup.find('h2', text=re.compile('RELATED STOCKS')).find_parent('div').find('table') It correctly get the table I am after.

问题 Selenium RC requires starting the server to kick of the execution of Selenium Automated RC test suites. The Selenium server is the inter mediator between browser and Selenium RC because Selenium RC won’t make direct call to browser. So we have to start Selenium server prior to start running Selenium RC test cases. In case of Selenium Web Driver , it does not required to start Selenium Server for executing test scripts. Selenium Web Driver makes the calls between browser & automation script.
