zipper | An implementation of Huet ’ s Zipper for Scala and Scala.js | JSON Processing library

I came across a json decoding error in an example in a book. The error says:

I'm trying to get a python Zip module to compress data.

But all it's doing is throwing an error:

I'm struggling with catching BeforeAttachmentAdd event. Sometimes it's just not fired, and I don't know why.

There are no exceptions, event is properly registered but it is not fired before adding attachment. I tried to find out when it is triggered and when not - no luck. Seems completely random to me.

Here's my code:

I wanted to install a new package in a Laravel 7 application. I have tried direct composer require command and tried manually entering package name and updating composer command but both times it returns error as follows. while using command 'composer require simplesoftwareio/simple-qrcode'

I am working on a little showcase that is supposed to demonstrate how you can write interactive programs in a purely functional manner using functional-reactive programming (specifically RxJava2).

My goal is to create a simple interactive game. The main function of the game (let's call it Next Game State, or NGS for short) takes the current state of the game, a user input, as well as a random number and computes the next state of the game from those three inputs. Fairly straightforward so far. The user inputs and the random numbers are Flowables that were created from Iterables or via generators. I envisioned that the game state itself would be a Flowable as well (but I might be wrong about that).

I am struggling to find the right functional-reactive operator that applies the function to the three inputs and produces the next state of the game. Initially, I thought that Flowable.zip(source1, source2, source3, zipper) would be right operation: it could take the three flows and combine it via the NGS function into a new Flowable. That, unfortunately, does not account for the fact that the resulting Flowable itself needs to be one of the inputs of the zip operation, which seems an impossible setup. My next idea was to use Flowable.generate, but I need the two additional inputs from other Flowables to calculate the next state, and there is no way to feed those into the generate operator.

In a nutshell, I'm trying to realize something similar to this (pseudo-)marble diagram:

OBJECTIVE: This function should take a single argument - an array of strings. Your scan function must loop through all the strings in this array, and examine each one using boolean logic.

If a string in the input array is equal to the value contraband, add the index of that item to an output array. When you have finished scanning the entire input array, return the output array, which should contain all the indexes of suspicious items in the array.

For example, given an input array of:

['contraband', 'apples', 'cats', 'contraband', 'contraband'] Your function should return the array:

[0, 3, 4] This list contains the position inside the input array of all the contraband strings.

MY CODE:

Solved, check the marked answer Seems the one marked with os.walk() executes faster.

(Python 3.8, zipfile module, Windows 10 Anaconda)

I was using the zipfile module of python to create Zip Files of my folders.

My Folder was D:/Personals. An os.listdir of personals yields 2 folders and 171 files. When I checked the zip it contained all the 171 files of the folder and the 2 inner nested folders. But the inner nested folders were empty, though each contained many individual files. Here is my code.

Having an issue with the following as I learn JS basics. My If was working before I stuck it inside the For, but now nothing seems to be working. Thought about doing forEach but seems like a complex solution for such a simple problem (creating another function to run forEach with). Also been running it through online code checkers and it is coming back clean.

Hoping I'm doing something ignorant like misaligned tabs..
