I am trying to loop through a dataframe but I am getting a for row in i["Attachments"]: TypeError: list indices must be integers or slices, not str
My JSON file has Attachments yet it is giving me errors. I have possibly tried all ways from Stackoverflow to get this issue solved, but to my dismay none of them really worked.
this is my Json file
idx.json

QUESTION
I have to do a program that's simulating the move of an ant in a 5x5 grid map,of cells. Imagine an 5x5 array in which, in position (2,2) and (3,3) there is food for ants to collect. Every ant starts moving from its nest which is in a specific cell (1,4 or 4,1). There is a method called move() that i have to write,which moves the ant one cell in each call. The move can either be horizontal or vertical. Also the ant cant move to his last position (to avoid going back and forth). Also each cell has 'smell points' and the ant prefers to go in the cell with the biggest points(so you compare its available options and pick the one with the biggest smell points,simple right?). Now, the problem. They want the ant to make completely random moves incase the cell has no smell points or the smell points of the available cells are equal. So to sum it up:
- if statement to check in which cell the ant is. When you find it you know where to look for his previous move.
- nested if statement to check in which cell the ant was last. That's 3 or 4 if statements in a 5x5 area. When you find the last,in which the ant can't move,you know which cells to compare .
- nested if statement between 2 or 3 cells to find the one with the most smell points.
- nested if statement in case their smell points are equal or 0. In this case the ant moves completely random( i made it via Math.random() ). All the above is for just one cell!. Each cell has different options because of its location in map. So to make this as you can see i need way too many if statements. I can't even count them without getting mind blowned! But i can't imagine a way to make this without if statements. Also every cell its different and the ant has different options to move , so I can't categorise it . For example , imagine the ant is in (1,1) . It can go to (1,2) or (2,1) only . If it is at (4,2) it can go to (4,3)or(3,2)or(4,1)or(5,2)! You have to make 4 if statement to check which one of these was his last position and then go on with the other nested ifs... So what do you think? Is it wrong to have so many ifs?
ANSWER
Answered 2020-Dec-03 at 00:29This does sound like too many if
statements. Here are some suggestions:
You should remember where the ant is in a variable. I don't think you need any if statements to check which cell the ant is in.
You should remember where the ant was last in a different variable.
You should make a list of the surrounding points and their smell points. Then remove from this list the ants previous location.
Using the above collection, you can loop through to pick the right one or if there is more than one choose one at random from the collection.
When you move the ant, set the previous location to the current location and then update the current location.

Hi everybody: I'm creating a repository in Maven with Cucumber, Selenium, TestNG.
What I'm trying to do is getting the values from a properties file for sending these parameters with Selenium, but I cannot reach with the solution to the issues generated here.
This is the structure of my project:

Answered 2020-Feb-19 at 23:16It's important to read the exception message carefully. The exception is not related to pico container. But rather pico container is telling you about a problem with your step definitions.
QUESTION
I'm making a React application using an external API. But I face a small issue atm. I need to make a single GET request to every ID that I have. It's possible that I need to make up to 1000 GET requests and the problem of that is the time it takes to get all the data. Is there a way of making let's say 1000 GET requests without waiting for each of them to resolve? I have this but it takes for ever.
...ANSWER
Answered 2020-Apr-11 at 21:45Probably you need to check out something like bulk
routes for the API. So e.g. you can set the array of match_id
s and make only one request and get the array of data.
Otherwise you need to wait for each request to be executed.

I’ve been looking at a lot of example Selenium frameworks with Page Object Models, they typically show:
...ANSWER
Answered 2020-Feb-01 at 21:19I see one big disadvantage - you cannot run your tests parallel. If you have a static driver that means, you can execute only one test at the time. One of the rules of tests is that test should not be dependent on any other test. It would be violated.
So what are the choices? I prefer to chain the methods, to make it more fluent. Let's assume that the LoginPage looks like this:
QUESTION
Could not be translated... See go.microsoft.com/fwlink/?linkid=2101038
Can't I use Include()
anymore? Is it better I start to using raw SQL commands?
ANSWER
Answered 2019-Dec-04 at 08:09Can't I use Include() anymore? Is it better I start to using raw SQL commands?
That's not related to Include()
but because you're using GroupBy(m=> m.Name)
. See breaking chagnes.
Here's a description about Groupby
quoted from the official docs:
The SQL GROUP BY is restrictive too. It requires you to group only by scalar values.The projection can only contain grouping key columns or any aggregate applied over a column. EF Core identifies this pattern and translates it to the server
To fix that issue, you should use aGroupBy()
that can be translated into SQL:

QUESTION
TextFixture and Test
...ANSWER
Answered 2019-Oct-23 at 04:24From https://xunit.net/docs/shared-context#class-fixture
You can use the class fixture feature of xUnit.net to share a single object instance among all tests in a test class
Notice in a test class
In you case you have two separated classes HomeTest
and ProfileTest
, regardless of both are derived from same abstracted class, they are treated by xUnit as two different test classes.
Consider to use Collection Fixtures
instead.
https://xunit.net/docs/shared-context#collection-fixture
You can use the collection fixture feature of xUnit.net to share a single object instance among tests in several test class

public override void IsAt() => Assert.IsTrue(Browsers.Title.Equals("home"));
}
...ANSWER
Answered 2019-Oct-08 at 10:52You can kind of do this, but just because you can do something, it does not mean it is a good idea. Think if it really makes the code easier to understand or not. Sometimes the amount of abstraction makes it just not worth it
QUESTION
I found the Pages
with a static getPages<>()
method.
ANSWER
Answered 2019-Sep-30 at 12:42It makes and returns a new instance, but the way to access this getter is a static method.
The property "Dashboard" is static, that means that you can access it from the class definition and you do not need an instance of the "Pages" class to get to it.
But because the property is a getter that runs a function, and because that function returns a new instance every time, you end up with a new instance each time.
