Python

I have data in two columns, X and Y where the function Y changes for increasing values of the X variable. If Y shows variations with X, the simplest way to do this is by fitting the data with a linear function.(In python), but I am looking for some "advanced" strategy (other than linear regression, i.e., using Neural Networks or other machine learning techniques) to elaborate on these data because i also want to find pattern in it. Need guidance .

Hello, I would like to ask a question, the size of the space occupied by python before executing file = f.read() is 84M， The size of the space occupied by python after execution is 2689MB, and the size of the file only is 1.27GB, why does it take up so much more space than the file size

This year politicians and economists have been invited to participate in Stanford Institute for Theoretical Economics (SITE 2021) conference as guests. You have to accommodate them in r rooms such that-
No room may remain empty.
A room may contain either only politicians or only economists, not both.
No economists are allowed to stay alone in a room.
Find the number of ways to place them. Note though, that all the rooms are identical. But each of the economists and politicians are unique.
Since the number of ways can be very large, print the answer modulo 998,244,353.
Input Format:
The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.
The first and only line of each test case contains three space-separated integers p, q and r denoting the number of politicians, economists and rooms.
Output Format:
For each test case, output the number of ways to place them modulo 998,244,353.
Constraints
1≤T≤100
1≤p,q,r≤100
Sample Input:
4
2 1 4
2 4 4
2 5 4 
2 8 4
Sample Output:

609
Explanation:
 Test case 1: 4 rooms and 3 people. A room would remain empty.
 Test case 2: There are 4 rooms and 6 people. There are 3 possible ways to distribute these 6 people in 3 rooms.

{Politician 1}, {Politician 2}, {Economist 1, Economist 2}, {Economist 3, Economist 4}
{Politician 1}, {Politician 2}, {Economist 1, Economist 3}, {Economist 2, Economist 4}
{Politician 1}, {Politician 2}, {Economist 1, Economist 4}, {Economist 2, Economist 3}
 Please note that the rooms are identical.

from functools import partial

def multiply(x, y):
        return x * y

 # create a new function that multiplies by 2
dbl = partial(multiply, 2)
print(dbl(4))
