intro | An introduction presentation for GDG Aracaju events | Runtime Evironment library

I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.

I was looking at the Microsoft Rust guide and while reading the generics chapters, I came across the following problem.

Consider the two following pieces of code:

I am creating a website and, on the opening of the homepage, I have a poster of a video inviting to enter the website, then after clicking on the poster my video (MP4 format) is read.

I tried to do some JS/CSS stuff to hide it after it has been read but I must miss something in the process, that's why I'm asking for some help.

My actual code in the parts where we are interested about :

I'm going through this MIT Intro to Comp Sci Using Python course on Edx. There is an exercise telling us to use bisection search and recursion to check if a character is in an alphabetically ordered string. For some reason, I got a syntax error when I put the variable HALF after that If-statement, while I won't get an error if I declare it before the If-statement. All I could find is not being able to declare local variables in an If-statement. Please tell me or refer me to websites explaining why this happens? Thanks a bunch.

Here's the code:

i hope you can help, because I'm running out of knowledge. My Problem: i want to change a variable to a new value:

My programming class requires us to use a program that checks our code and makes sure its perfect with the example given that we are supposed to try to copy. Well my program asks for someones shoe size but it won't let me pass the lesson because I'm supposed to be able to have a decimal place at all times for the shoe size. For example you can't just have 6 you have to have 6.0. Here is my code:

So, I'm pretty sure this should be possible without choice. Maybe I am wrong.

Here is a minimal reproducible example of what I'm trying to do:

I am creating a text-based game for a school project. I am a novice and found a pretty good YouTube tutorial. I am following along in the beginning pretty closely so that I may understand better. I've entered this code almost identical to what the tutorial has stated and the code in the tutorial works but mine does not. What am I doing wrong? My output is as follows...

I am making a game in python, and am displaying an image. I would use pygame, but the effects I am making won't be used in pygame. I looked it up and used pillow because it requires the least code. Open vc looked a little complicated.
