Convert a file into dictionary

Question

I have a file comprising three columns, i.e. a 1 4 b 2 5 c 3 6 I wish to read this file to a dictionary so that column 1 is the key and column 2 and 3 is the value, i.e.,

dict = {'a': (1,4), 'b': (2,5), 'c': (3,6)}

Does anyone have a command for this?

Added the tag to your question. Nevertheless, what have you tried so far? — home, Mar 18 '18 at 17:41
For example, I have tried this link `https://stackoverflow.com/questions/4803999/how-to-convert-a-file-into-a-dictionary`, but none of them work for me. Moreover, I have three columns, not two. — Alexander West, Mar 18 '18 at 17:45

It is the same as the one in the link you mentioned in the comments. Except you unpack three values in a line instead of two.

test.txt (your text file)

a 1 4
b 2 5
c 3 6

Your code:

d = {}
with open("test.txt") as f:
    for line in f:
       (key, val1, val2) = line.split()
       d[key] = (int(val1), int(val2))

print(d)

gives you,

{'a': (1, 4), 'b': (2, 5), 'c': (3, 6)}
