To interpolate, you need the "relative position" of the missing point, relative to the "two" points on "either side" of the missing value. In other words, you can't interpolate unless you have at least 2 points to start with, and you know...

There are many different types of algorithms in machine learning. Among others, you have supervised, unsupervised and reinforcement learning tasks. Each of these types have different input and output requirements. Classification and regression...
First off, there is no code to give feedback to here, so the answer is not very good in that respect. In mathematics, there are different ways of interpolating points. There is the Lagrangian ineterpolation, or Newton interpolation. These are...
The problem is you're subtracting the joined date from the current date and seeing if it is EQUAL to 9. That will only ever match a single date. In your example, that would be everyone who joined only on 6/21, or (6/30 - 6/21 = 9). If you're...
It seems to me there is no need to utilize a pointer to store age as shown below If you wish to utilize a pointer you should delete it before copying to it in the copy constructor else you will have memory leakage As to your question if I...
Coming up with the "step-by-step" is your job. That's the point of the exercise. You have to think about the problem and come up with the algorithm that solves it. Do it on paper, one step at a time, and document precisely what you're doing at...

To add to what Richard has rightly said, syntax errors like these are a fact of life, and we all meet them on a daily basis - often several per minute if you aren't careful. So it's worth investing a couple of minutes in learning how to spot and...

This is a massive project so I'm not sure what you are expecting us to tell you. It sounds like you need to design this out better, create a database to store your data, and then start writing code to do what you want.

Well, there's a couple bottlenecks. First, Python is an interpreted language so it's going to be slower than compiled languages. Second, try and read 5.5GB of data and do NOTHING with it. Just read the files and throw the content you read away....

If you are going to use a database, use it properly - in a format where that data can be stored a single time and queried within that DB. Storing Excel files in your DB does not pass the second criteria and very often fails the first as well. ...
