QUESTION
I'd like to do an Europe map, so I was trying with this code but I don't really know how it works.

Answered 2021-May-19 at 18:16I think you assumed that the europa object still had an item named @data
, but if you look at it that is not the case:

I am having some problems with my code for my MSc thesis. I am following https://github.com/ErikaWarnatzsch/Malawi-Future-Climate-Modelling-Assessment/edit/master/Histogram_TasMAX.py model to be able to build a Histogram for future RCP scenarios (4.5 and 8.5) while using historical and observed data.
The region I am looking at lies along the Central belt of Colombia.

QUESTION
So I'm relatively new to coding and have recently taken the monstrous task of building a few climate models for my MSc thesis. Using this code I have adapted it and it now shows no error messages except now it doesn't show any figure as an output. Any solutions?
I input
%matplotlib notebook
at the top of the code, and also put plt.show();
at the bottom of the script (as per some recommendations through some similar queries)... but still doesn't work. Prior to this it was showing
Any recommendations/solutions?
Thanks!
As requested - my code:
...ANSWER
Answered 2020-Jul-07 at 17:20In the code, you are never calling the main
function, so the figure you are showing is empty.
You should call main()
at some point in your code before the plt.gcf()
or plt.show
.
Edit
In more detail:
You are writing your main()
function in this snippet of code, and then, without indent, you are calling pyplot
to get the current figure
, where pyplot
just gives you en empty figure
back (the gcf()
-call is not necessary anyways in your code) and plt.show()
shows no an empty figure.
You can or cannot move the plt.show()
into you main()
function, but at one point you must definitely call that function otherwise none of it is executed.
Edit 2:

QUESTION
I'm trying to setup VSCode to build and debug C on Windows. I have installed MinGW.
I'm trying to generate an .exe file for the following code:
...ANSWER
Answered 2020-May-14 at 15:59Your first question:
When you use the powershell command, it gets your *.c
files from your current wording directory via relative paths. This is what you attempt to do in the task
command, but your CWD
is set to the wrong place. In tasks.json
, you need to either specify the absolute paths of your files in the gcc
command or change your CWD to the directory of the *.c
files. Or better, VSC lets you set "cwd": "${workspaceFolder}"
. This means if you change the name or do any other edits, your task will still work. (For bonus points, you could set the CWD to the enclosing folder of the currently selected file.) First question part 2: The task error probably isn't you. It appears to be a known bug. Instructions here to mitigate it.
Sorry for the late response
I don't see any reason why you would get the debugging error, so my only guess is a permissions problem. Your debugger may not be able to "see" that that directory exists. Make sure neither it nor any of its parent folders have unduly tights restrictions.
QUESTION
I am trying to get the adresses for all postal access points in Belgium from this site: https://www.ibpt.be/en/consumers/post/cartography
I am using Selenium with python 3, and I can't seem to get it to work, even though it normally works on other sites. I figure it might be because the map is special in some way? (But I thought this is when Selenium is actually necessary).
Below is the very simple code I am trying to get to work (eventually I need to also paste a zip code and save the results, but first off, I can't even get it to click the search button).
Anyone who can help? (btw, if there is an easier and faster way to do this (without Selenium), please do share).

Answered 2020-Feb-26 at 09:38As the the desired element is within an </code> so to invoke <code>click()</code> on the element you have to:</p>
<ul>
<li>Induce <em>WebDriverWait</em> for the desired <em>frame to be available and switch to it</em>.</li>
<li>Induce <em>WebDriverWait</em> for the desired <em>element to be clickable</em>.</li>
<li><p>You can use the following solution:</p>
<ul>
<li><p>Using <code>CSS_SELECTOR</code>:</p>
<pre><code>driver.get('https://www.ibpt.be/en/consumers/post/cartography')
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[src*='postalpoint']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.search-location-button>input.bt-search[value='Search']"))).click()
</code></pre></li>
<li><p>Using <code>XPATH</code>:</p>
<pre><code>driver.get('https://www.ibpt.be/en/consumers/post/cartography')
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[contains(@src, 'postalpoint')]")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='search-location-button']/input[@class='bt-search' and @value='Search']"))).click()
</code></pre></li>
<li><p><strong>Note</strong> : You have to add the following imports :</p>
<pre><code>from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
