QUESTION
ANSWER
Answered 2021-Jun-06 at 06:35Ok I figured out your issue.
In your "stylesheet.css" you have this code:
QUESTION
package com.company;
import java.lang.reflect.Type;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// write your code here
Scanner nameInput = new Scanner(System.in);
System.out.printf("As of right now I noticed you have not selected a weapon. Please choose from the following selections that I recommend, I current have no information on your shooting style.\nSo these recommendations are based souly on beginner levels.");
System.out.printf(Gun.Type);
}
}
...ANSWER
Answered 2021-May-08 at 17:24You have multiple problems with your code example. Here are a few.
The gunList
method is declared as returning a String
. But you do not return a string. Instead you print to System.out
, a PrintStream
object. Change that to capture the generated text as a String
. See Sprintf equivalent in Java. Return that string object using the return
keyword.
There is no need for the public String Type() {
. (Also, methods in Java should be named starting with a lowercase letter.) Just instantiate a Guns
object, and call gunList
method. (Also, using “list” here in this method name is a poor choice, as that word has a specific commonly-used meaning in Java.)
QUESTION
I needed some help in getting my first open source project that I want to work on to run on my machine. I have a 2018 MacBook Pro 15” running Big Sur 11.1 (20C69). I am using VS Code as my IDE. I have forked and cloned the repository for my project.
I have followed the instructions on how to get the app to run here:

Here are the errors I get in terminal:

I have two lists, which ones I want to compare their elements:
A remote list called groups

Answered 2020-Nov-30 at 11:43I think you want to find group names that exist in one list but not two lists.
So here is my solution:

QUESTION
I am new to python and I don't really understand the sql thing that well. Currently on the 6th week of team treehouse so please bare with me here if these are noob questions.
Goal
- Import CSV with stock_tickers and 5 other columns of data
- Convert CSV into pandas dataframe
- Import dataframe into database. If there is already the unique stock_ticker for it to not add a new row, but next to check if the data in the other 5 columns is different. If it is than update it.
Right now I can do steps #1 and #2 and half of #3. With the help on here was able to get the looping thing to work. If there is a new stock_ticker row in the csv it will add it to database. If the data changes for an existing stock_ticker it won't do any updates.

QUESTION
Question 1 How do I use an new IP Address before the API Request is made?
Question 2 Is there a good way to test if this IP thing actually worked other than printing results of grabbed IP
I made a new file with list of IPs in each line and I grab the proxy using
...ANSWER
Answered 2020-Sep-08 at 03:12Looks like you're putting the proxy into the
params
, which is the data that gets posted to the server; instead, you need to pass it torequests.get()
so that it knows how to make the request.
QUESTION
When running npm install
to download project dependencies, sqlite3
encounters an error and never installs. Trying npm install sqlite3
produces same error.
Running on Linux Beta (Debian v10 buster) on ChromeOS.
Installs fine on others' machines. Expect it has something to do with ChromeOS.

can't download a prebuilt binary and thus falls back to building it with node-gyp
. This is where the build fails.
Note the line in your log where it says: gyp ERR! stack Error: not found: make
It seems as if you don't have make
installed. Since you're on Debian, you should be able to install make
by running: sudo apt-get install build-essential
.
This question has already been extensively discussed in the following question: npm failed to install time with make not found error
Make sure to take a close look at error messages :)
QUESTION
I'm trying to do some treehouse tutorials on C#. Unfortunately, the instructor is teaching this course in an windows machine with a windows version of VS Community while I follow along VS Community for mac. Got to a point where she is trying to use the C# interactive (REPL) but I can't seem to find it on the mac version. Anyone know if its even possible to do this on the mac? Thanks.
...ANSWER
Answered 2017-Aug-05 at 04:17No Interactive Window support in VS 2017 Mac.
Future versions may have this feature. If it is important you could use Parallels and run the Windows version.
Or work around it by doing the same sorts of things with a debugger and Immediate Window.
QUESTION
I am using the quicksort algorithm in Python whereby it swaps the values in place. My question is how does Python know I am using the same list in the Partition and quicksort function?
As you can see below in my code for quicksort, the swap for the position of the values only happens in the partition function. Yet, without needing to do a return of the list to the quicksort function, it knows that I swapped the position of the values for the list in partition, thus printing the sorted list.
...ANSWER
Answered 2020-Apr-15 at 14:49This is because values are passed by reference in python. When you pass your lst
to your partition
function, you are actually passing a reference to your list in your quicksort
function, and not a copy of the list.
