When I try to export my pandas data frame to excel only one row exports.

The data base is created during a large loop which basically gives the output:

I have managed to create a web scraper that can collect the item descriptions however the page loads more items as it scrolls.

The average daily sales are part of a graph which is why I am struggling to scrape the data. If there is a way to scrape the data from the graph(mainly the sales per day) help would be much appreciated.

I have a question that sorts data from a car report of txt file.

The question is: How do I listed cars sorted by their MAKE (Ford, Chevy ..etc). They only need the MAKE to be sorted so they can be all FORD cars under each other, then Chevy, DODGE .. so on and so forth like this:

And this is what I have so far:

Here's my source code:

I have a Java question that deals with reading the txt file and pulling data from it.

It's a bunch of used cars stored in a txt report file. They have several different lots that they sell from. The lots are identified by the 5 digit zip code followed by a zip code extension at the beginning of each record. They would like a report that lists all cars sold from all lots. This is what I come up with:

They would like the report to list 30 cars per page, on the report. Each page is to have headings and a page number. Like this:

My question is how do I list 30 cars per page instead of all together (Each page 30 cars with headings and page #)?

Here's my source code:

I'm developing an android application with Augmented Reality. Where we can place different sound sources in planes. When users move away from those objects I want to make the sound less intense according to the distance. I've distance from the sound source but how can I manipulate audio? Is there any good library for working with sound in android or java.

I know a little bit about Doppler Effect where sound source moves from a stationary object when the sound source moves towards stationary object pitch increase on the other hand when moves away then pitch decreases. Does it make sense to use in my case?

Working with arrays is definitely one of my weakest area, so any help is greatly appreciated.

To add to the challange, this is for a WebOS application that has the following limitations ...

• JavaScript 5.0
• Only extra library is JQuery
• No arrow functions (=>)

Example of received array ...

I need read a csv file and fill the empty/null values in column "Phone and Email" based on the person's address and write to a new csv file. Ex: if a person "Jonas Kahnwald" doesn't have the phone number or an email address but has the same address as the person above or below, say "Hannah Kahnwald", then we should fill the empty/null values with those person's details.

I won't be able to use python pandas as the rest of the code/programs are purely based on python 2.7 (unfortunately), so I just need to write a function or a logic to capture this information alone.

Input format/table looks like below with empty cells (csv file):

I have a data set and I tried to find approxQuantile. It works for sample set but not with window function.
