I have two files one has key and other has both key and value. I have to match the key of file one and pull the corresponding value from file two. When all the key and value are in plain column format i can get the key and value to a new file very well. But I am not understanding how to get a result when the value is in set/array type.

Input one in column format:

5216 3911 2 761.00 
2503 1417 13 102866.00
5570 50 2 3718.00 
5391 1534 3 11958.00 
5015 4078 1 817.00 
3430 299 1 5119.00 
4504 3369 2 3218.00  
4069 4020 2 17854.00 
5164 4163 1 107.00 
3589 3026 1 7363.00 

Input two in column format. They are key as pair i.e. col[0] and col[1] both are key as pairs

5391 1534 
5015 4078 
3430 299 
4504 3369  

Output for the above input case, which is right for me

5391 1534 3 11958.00 
5015 4078 1 817.00 
3430 299 1 5119.00 
4504 3369 2 3218.00 

Program

from collections import defaultdictedges = {}
with open('Input_1.txt', 'r') as edge_data:    for row in edge_data:col = row.strip().split()edges[col[0], col[1]] = col[2], col[3]
#Then to do the queries, read through the first file and print out the matches:
with open('Input_2', 'r') as classified_data:with open ('Output', 'w') as outfile:    for row in classified_data:a,b = row.strip().split()c = edges.get((a,b), edges.get((b,a)))#print a,b, edges.get((a,b), edges.get((b,a)))#print a,b,c        outfile.write("%s %s %s\n" % (a,b,c))

The above program works great for the above given input types. But I have no clue how to get the operations for the below given inputs.

I understand I am supposed to change this statement from the above program but I am not getting any clue what should that be changed to ?

edges[col[0], col[1]] = col[2], col[3]

New Input one

('3350', '2542') [6089.0, 4315.0] 
('2655', '1411') [559.0, 1220.0, 166.0, 256.0, 146.0, 528.0, 1902.0, 880.0, 2317.0, 2868.0] 
('4212', '1613') [150.0, 14184.0, 4249.0, 1250.0, 10138.0, 4281.0, 2846.0, 2205.0, 1651.0, 335.0, 5233.0, 149.0, 6816.0] 
('4750', '2247') [3089.0] 
('5305', '3341') [13122.0]

New Input two They are key as pair i.e. col[0] and col[1] both are key as pairs

3350 2542
4750 2247
5305 3341

Expected output is

3350 2542 6089.0
3350 2542 4315.0
4750 2247 3089.0
5305 3341 13122.0

I thought @three_pineapples's eval manner is quite good and brilliant,

Here is an alternative one which only manipulate string:

edges = {}
with open("Input_1.txt", "r") as edge_data:for row in edge_data:k, v = row.strip().split(")") # split as key, valuek = " ".join(i.strip("'") for i in k.strip("(").split(", ")) # clean unwanted symbol and merge togetherv = v.strip(" []").split(", ") # get list valueedges[k] = vwith open("Input_2", "r") as classified_data:for row in classified_data:k = row.strip();for v in edges.get(k, []):print k, v
