I have a movieDetails.json database and the collection name is a movie then our teacher wants us to Display the number of movies based on the number of directors a movie has a. Hint you might have to use the javascript function split Since the director is not an array, it is only a string so I can't count how many directors are there because it will always come out as 1 since its a string so I want to split that string so that I can get an array so that I can count it. But unfortunately, I don't know the query that will solve this problem. ex. of expected output:

Say we have pandas dataframe:

After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:

I'm looking for some general information on how to secure my backend running on AWS. I have mobile apps that send requests to PHP scripts living in AWS EC2 instance configured with NGINX. Only thing PHP scripts do is querying MySQL database and echo the json response back to the app. I was looking for options to enhance security of the backend against DDoS attacks and such. I do not have any web contents the users can interact with but just these PHP endpoints which apps communicate with to retrieve data.

1. In my case, will AWS Cloudfront be helpful? As far as I understand, CloudFront is for CDN, which deals with static web contents that can be distributed to different servers, but since I don't have any websites, and the PHP files are just serving data back to the mobile apps, I'm not sure how it can help.

2. Also they say AWS Shield is enabled by default, but I'm not sure if that's only useful if I use AWS-API they provide as a service rather than me just having php scripts uploaded to EC2 instance on my own.

With the way I have php files on the server, I'm wondering if my backend gets all the goodies AWS is boasting about their security in general.

I know the question is very generic but as a starter, any advice to what AWS products/options I might be able to opt-in for to make the backend more secure will be appreciated.

Thank you

I have 2 blocks of code. One with a single while loop, and the second with a for loop inside the while loop. My professor is telling me that Option 1 has an algorithm complexity of O(n) and Option 2 has an algorithm complexity of O(n^2), however can't explain why that is, other than pointing to the nested for loops. I am confused because both perform the exact same number of calculations for any given size N, which doesn't seem to be indicative that they have different algorithm complexities.

I'd like to know:

a) if my professor is correct, and how they can boast the same calculations but have different big Os.

b) if my professor is incorrect and they are the same complexity, is it O(n) or O(n^2)? Why?

I've used inline comments denoted by '#' to note the computations. Packages to deliver should be N. Self.trucks is a list. self.isWorkDayComplete is a boolean determined by whether all packages have been delivered.

Option 1:

I am trying to write a program that will generate a short and simple description for real estate properties. I have (array) word banks with adjectives, prompts for inputs with specific details (square footage, # of bedrooms etc), two functions with else if statements that will generate a specific sentences, and then a "description" variable that joins these sentences, prompted inputs and word bank adjectives together.

I am having trouble calling the result of the functions in the last description variable. I stored the functions as a variable with the variable it is assessing (location and walkDist) within it. When I run this program it doesn't give me the prompts for these variables and prints out the code of the functions instead of the sentence I want it to.

When I take location and walkDist out of the functions I get the prompt but the webpage returns an error after I input a 0,1,2.

The function isn't being recognized as a function for some reason. Is there something I am missing or is there a better way to store the else if without a function for this use case?

While browsing Redis command reference, I came across two very similar comands:

• SET with EX option: https://redis.io/commands/set
• SETEX: https://redis.io/commands/setex

The SETEX boasts itself as an atomic way to do SET and EXPIRE, yet by the looks of it the same thing can be achieved with SET EX as it's also a single command.

SETEX was added in 2.0.0, while EX parameter was added in 2.6.12, so it seems that the former remains for the backwards compatibility, but for some reason it's not marked as deprecated.

Did I miss anything? Are there any valid cases for using SETEX nowadays?

I'm trying to position an image below a piece of text when in mobile view, but, in it's current state, it's overwriting the block of text.

This is how it looks on desktop:

[![enter image description here][1]][1]

This is how it looks on mobile at the moment (the image is covering the text):

[![enter image description here][2]][2]

How I want it to look:

[![enter image description here][3]][3]

The general concept it to get the image between the text and button. I have tried to 'display:block' - my thinking was that if it's classed as a separate element, it will just slide after the text automatically, but to no success.

Any help would be appreciated.
