river | Dynamic binary translator for x86 binaries | Parser library

I am new to python . i am trying to run the below code but the results are not as expected:

So, I'm currently a student in an intro to computer science course, and for my final I'm working with a text file of books with information attached.

I have a function which asks for a start year, and an end year. The function will then print out all of the books within the year range given by the user.

The problem I'm having is that the same book is being printed multiple times.

I have version 90 of Chrome so tag should work here. But it always goes to fallback. When I comment , nothing is shown on the screen.

The code:

Working with react leaflet and a water api. I create an array of objects from the data obtained from the API, console log shows I have all the correct data, particularly at line 109 it does output the correct information. Yet, on lines 254 and 255, using obj2[1] just gives me 'TypeError: Cannot read property 'name' of undefined.' Switching the index at those two lines back to 0 makes it compiles and run, but that's obviously not the right data. What is going on here?

I have no training in graph theory, so my terminology is poor. I have a directed tree graph that has "redundant nodes." I am defining "redundant nodes" as those with degree=2 in my tree graph. I would like to find an efficient way to return all the paths between all non-redundant nodes, preferably using NetworkX (Python) tools. This really simple graphic demonstrates what I'm trying to achieve:

So given this graph, I'd like to return three paths (p1, p2, and p3) that represent the connections between 1->4, 5->4, and 4->7.

I can write an algorithm to do this "manually", in the sense that I start at nodes with degree=1 and "walk" along the graph until I hit another non-degree=2 node. However, I suspect that there is already a formalized way to do this kind of analysis, but I can't seem to figure it out.

For more context, my graphs are much larger and more complicated as they're representations of river networks, something like this:

But they're always trees, no cycles.

I'm having a hard time with creating a Sql that pull data from three tables.

Here are part of the structure of each table:

I am trying to create a dynamic dropdown menu using ajax but its not loading the list. My dropdownlist is loaded from my controller for both the categories and the brands. But I cant seem to get the brands dropdownlist load dynamically on selection from the category dropdownlist. I don't know where I am getting it wrong.

My Blade file

Imagine that I have a list of countries, and for each country I want to store some info ( animal, fruit, river) of it. But the number of animals, fruit and rivers is unknown, it is input from user. Therefore, I want to use list in class as below but don't know how to append the list.

Any idea why the regular expression below cuts the 'fl' part of the sentence ?
