QUESTION
I'm trying to create a simple quiz with struct. But my program here is very repetitive. How can I modify it and make it more efficient? Especially to check if the answers are correct I do not want to declare a separate variable and store it as int correct
. Thank You.
ANSWER
Answered 2021-Jun-11 at 09:50The only thing you can do is define the correct
variable in the struct itself. You can use a loop for decreasing the repetitiveness but obviously the question and the answers will have to be stored, it cannot be simplified further.
QUESTION
I am converting csv to json
- I m merging the Email flag if country is same.
csv file is below
...ANSWER
Answered 2021-Jun-11 at 08:06How about the following approach. Use a DictReader()
to read the CSV in as dictionary rows. This will automatically add None
for missing keys. Use a defaultdict(list)
to group rows by country. Then build your required output format:

QUESTION
I'm trying to create a very simple easy game with multiple rounds and each round has three questions.
If you answer the wrong answer to a question in one round, you have to start the round again from the top. Once you have answered two questions correctly, you have a final question where if you answer this right you add 1 to the answer pot. After this you move on to the next round.
I am trying to figure out how to loop back to the start of the round that you are currently on if you get an answer wrong. At the moment if you get an answer wrong in the first round, you just go straight on into the second round.
Any ideas on how I can integrate a loop into the incorrect answer statements so they start that round again before they are able to move on? Thank you!
...ANSWER
Answered 2021-Jun-03 at 09:29A good way to solve this would be error handling - create a custom Exception
and throw it whenever a wrong answer is given. Loop until you passed all questions without exception and then break.
I also modified your ask-function , there is no need for recursion in it, simply loop and return when a valid answer is given.
QUESTION
I have a data frame called animals
containing different sized columns that have some common and uncommon elements among each other as shown below:
ANSWER
Answered 2021-Jun-01 at 00:49We can use intersect
QUESTION
The xml format is a good way to store any hierarchical data. As an example we are using the classification of animals
...ANSWER
Answered 2021-May-28 at 10:32What we can see in the html table, is that the first row holds a cell for every hierarchy level which is represented as a column. This means it has to be generated a row with all elements from the highest till the deepest hierarchy level. The element on the deepest hierarchy level is the one without further descendants. To get these we can use this xpath expression
QUESTION
I know this question has been asked before but I'v tried different approaches and I can't seem to be able to fix it.
I know I have to reset my important global variables in order to correctly restart the game. The reset of those variables is done when lives == 0 -> I reset the global variables, main menu becomes True and Game False which should put me back in the main menu.
However when I run my game, as soon as the lives reach 0 the code finishes and exits -> Process finished with exit code 0.
The issue must be in my while game loop but I'm unsure what I'm doing wrong. I'v also tried wrapping my game logic in a function, this seems to mess with my game since I only get the frozen state screen, no enemy spawning and not able to move.
Any ideas what might cause this issue?
Full code:
...ANSWER
Answered 2021-May-21 at 19:14You are setting game = False, but using that in the while loop. As soon as game is set to False the while loop exits and the game ends. If you want to do it this way, use another variable in the while loop:
QUESTION
So I currently have an Enemy Class that uses sprite groups and a projectile class that does not use sprite groups.
I check the collision of my projectiles against the enemies in the sprite group. If an enemy is hit, the enemy sprite gets removed, the score is incremented and the bullet gets removed from the screen. At the moment only the enemy sprite gets removed.
Projectile Class:
...ANSWER
Answered 2021-May-08 at 17:17I can't see the drawing code so I am guessing that you are still drawing the beam. Make beams a spritegroup and do this in the loop (not in the beams class)
pygame.sprite.groupcollide(beams, speedboats, True, True)
Which will remove both from their respective groups.
QUESTION
Ive downloaded and installed my docker-desktop gui client for my Windows 10 system. Everything went well during the installation process. But when I clicked on the docker desktop icon the small white whale shown on the notifications tab only reads "Docker Desktop is starting" for hours and hours without any change. Can anyone please provide me with a solution?
...ANSWER
Answered 2021-May-08 at 14:05I am facing the same issue. For me, the solution that works is to kill all of my docker desktop processes from the Task Manager and then click on the desktop client again. Usually, that fixes the problem most of the time. If not I keep trying the same method until it works.
