You need to recursively loop over the list and check if an item is iterable(strings are iterable too, but skip them) or not. itertools.chain will not work for [1,[2,2,2],4] because it requires all of it’s items to be iterable, but 1 and 4 (integers) are not iterable. That’s why it worked for the second one … Read more
You can use value_counts + isin – v = df.Parameter.value_counts() df[df.Parameter.isin(v.index[v.gt(5)])] For example, where K = 2 (get all items which have more than 2 readings) – df ID Parameter Value 0 0 A 4.3 1 1 B 3.1 2 2 C 8.9 3 3 A 2.1 4 4 A 3.9 5 5 B 4.5 … Read more
It sounds as if your save window should be modal. If this is a basic save window, why are you reinventing the wheel? Tk has a tkFileDialog for this purpose. If what you want is to override the default behaviour of destroying the window, you can simply do: root.protocol(‘WM_DELETE_WINDOW’, doSomething) # root is your root … Read more
Why not simply do something like this? >>> a array([[ 0., 5., 2.], [ 0., 0., 3.], [ 0., 0., 0.]]) >>> b array([ 0., 0., 3.]) >>> a==b array([[ True, False, False], [ True, True, True], [ True, True, False]], dtype=bool) >>> np.all(a==b,axis=1) array([False, True, False], dtype=bool) >>> np.where(np.all(a==b,axis=1)) (array([1]),)
Not sure if you can, generally for any page, do it after you have opened the page, but you can mute all the sound for the entire duration of the browser session by setting the –mute-audio switcher: from selenium import webdriver chrome_options = webdriver.ChromeOptions() chrome_options.add_argument(“–mute-audio”) driver = webdriver.Chrome(chrome_options=chrome_options) driver.get(“https://www.youtube.com/watch?v=hdw1uKiTI5c”) Or, you can mute the HTML5 … Read more
You can do it with a simple “contains” CSS selector: soup.select(“a[href*=location]”) Or, if only one link needs to be matched, use select_one(): soup.select_one(“a[href*=location]”) And, of course, there are many other ways – for instance, you can use find_all() providing the href argument which can have a regular expression value or a function: import re soup.find_all(“a”, … Read more
You didn’t specify if the order matters. If it does not, you can do this in >= Python 2.7: l1 = [‘a’, ‘b’, ‘c’, ‘b’, ‘c’] l2 = [‘a’, ‘b’, ‘c’, ‘b’] from collections import Counter c1 = Counter(l1) c2 = Counter(l2) diff = c1-c2 print list(diff.elements())
Using reverse and passing the name of url we can redirect to url with query string: #urls.py url(r’^search/$’, views.search, name=”search_view”) #views.py from django.shortcuts import redirect, reverse # in method return redirect(reverse(‘search_view’) + ‘?item=4’)
For dynamic execution of statements use the exec function: >>> exec(‘y = 3’) >>> y 3 eval usage: eval(expression). The expression argument is parsed and evaluated as a Python expression. e.g.: >>> s = 3 >>> eval(‘s == 3’) True >>> eval(‘s + 1’) 4 >>> eval(‘s’) 3 >>> eval(‘str(s) + “test”‘) ‘3test’
