A package for topsis score generation in mere moments
Project description
Lightning Fast Topsis Score Generator
By Vyom Chopra
"Topsis-Vyom-101917060":
A package that comes real handy when calculating topsis score. It's one stop destination for all Topsis related work.
"Using this topsis package, calculating topsis score is nothing more than a child's play."
The function 'build_topsis()' in this package, will return the final dataset with topsis score and corresponding rank column. This function takes three arguments:
- data: the original dataset upon which you want to calculate topsis score,
- weights: a list that contains the pre-determined weights for all the numeric columns (int/float),
- impacts: a list that contains the pre-determined impacts for all the numeric columns ('+'/'-')
To add such an amazing capability to your python workspace, simply type in the following command in the command prompt.
pip install Topsis-Vyom-101917060
This will install the topsis package in your workspace.
The build_topsis() have inbuilt functionality:
- to detect numeric columns and automatically calculate topsis score only off them.
- to check contents of both weights and impacts list for any discrepancy.
- to handle any exception raised.
Now, when you write your python code, simply add this amazing functionality into your code with just a tad bit of new line of code
import Topsis_Vyom_101917060
Sample Code
Let's see a sample case: Given below is a dataset of which, we need to find the topsis score and hence, corresponding rank.
Fund Name | P1 | P2 | P3 | P4 | P5 |
---|---|---|---|---|---|
M1 | 0.93 | 0.86 | 4.1 | 46.1 | 13 |
M2 | 0.67 | 0.45 | 6.1 | 44 | 12.81 |
M3 | 0.72 | 0.52 | 3.8 | 32.7 | 9.44 |
M4 | 0.73 | 0.53 | 4.1 | 45 | 12.59 |
M5 | 0.71 | 0.5 | 3.4 | 55.5 | 15.03 |
M6 | 0.74 | 0.55 | 7 | 63.3 | 17.9 |
M7 | 0.95 | 0.9 | 5.1 | 41.8 | 12.19 |
M8 | 0.63 | 0.4 | 7 | 63.5 | 17.88 |
weights = [1,1,1,1,1]
impacts = ['+','-','+','-','+']
In the code editor:
import pandas as pd
import Topsis_Vyom_101917060
data = pd.read_csv(input_data_path)
dataset = build_topsis(data,,weights,impacts)
print(dataset)
Hence, we get the final Output as:
Fund Name | P1 | P2 | P3 | P4 | P5 | Topsis Score | Rank |
---|---|---|---|---|---|---|---|
M1 | 0.93 | 0.86 | 4.1 | 46.1 | 13 | 0.368067725 | 8 |
M2 | 0.67 | 0.45 | 6.1 | 44 | 12.81 | 0.629815594 | 1 |
M3 | 0.72 | 0.52 | 3.8 | 32.7 | 9.44 | 0.488377092 | 5 |
M4 | 0.73 | 0.53 | 4.1 | 45 | 12.59 | 0.489923292 | 4 |
M5 | 0.71 | 0.5 | 3.4 | 55.5 | 15.03 | 0.461216998 | 6 |
M6 | 0.74 | 0.55 | 7 | 63.3 | 17.9 | 0.603048108 | 3 |
M7 | 0.95 | 0.9 | 5.1 | 41.8 | 12.19 | 0.416449713 | 7 |
M8 | 0.63 | 0.4 | 7 | 63.5 | 17.88 | 0.621465197 | 2 |
Isn't it amazing!!
