Get and then join all combinations of rows with strings and integers in Excel sheet

Question

I have an Excel sheet with 3 rows and 5 columns that I want to get all possible combinations of into one row for every combination. Using itertools gets all the combinations, but joining them into one row for each result and with different variables is too hard for me.

Type    Sort    Length  Width   Weight
Small   P1      4       1.3     11
Medium  P2      2       1.6     4
Large   P3      7       1.1     8

Expected results (all possible combinations of all lengths combined into one row for each iteration):

Small,               P1        4  1.3   11
Small, Medium        P1,P2     6  2.9   15
Small, Medium,Large  P1,P2,P3  13 4.0   23
Medium               P2        2  1.6   4
Medium, Large        P2,P3     9  2.7   12
Large                P3        7  1.1   8

Edit:

import pandas as pd
import itertools

read_file = pd.read_excel (r'Data_list.xlsx')
read_file.to_csv ('Data_list.csv', index=True, header=True)
input_dict = read_file.to_dict('data_list')

output_dict = dict()
k = 0
for dict_size in range(1,len(input_dict)+1):
    for combination in itertools.combinations(input_dict, dict_size):
    d=len(combination) 
    k = k+1                                                                                     
    res[k] = input_dict[i]                                                                      
                                                                                            
    if d == 1:                                                                                  
    res[k] = {key: res[i][key] + input_dict[i].get(key, '') for key in res[i].keys()}
    else:                                                                                       
    res[k] = {key: res[i][key] + input_dict[1].get(key, '') for key in res[i].keys()}             

df = pd.DataFrame(res)             
df = df.T                          
print(df)                          
df.to_excel('Combined_data.xlsx')  

Answer 1

The answer is in your question :)

Let's assume that you transform your excel into a CSV, which you read as a list of dicts (you can learn how to do this by reading the Python documentation)

You will need to use itertools.combination on i rounds (to have i-elements combinations), i going from 1 to the length of the initial list (included)

For each resulting list of combinations, you will have to perform your own transformation of elements (sum, string concatenation...)
