Getting values from list

Question

I got problem to get values from list.

I got opad1.txt file which looks like this:

4.6   2.3   1.9   0.4   0.2   6.8   0.4   0.0   0.1   5.5
0.0   0.4   3.5   0.3   2.3   0.1   0.0   0.0   4.0   1.5
1.5   0.7   0.7   4.9   4.2   1.3   2.7   3.9   6.5   1.2
0.2

I'm using code to read this file and convert each line to list

with open('opad1.txt') as f:
    opady = f.readlines()

dekada = [i.split() for i in opady]

And now i got problem to separate each value from list dekada. When i use:

print(dekada[0])

The return is:

['4.6', '2.3', '1.9', '0.4', '0.2', '6.8', '0.4', '0.0', '0.1', '5.5']

My question is how to reach first element only '4.6' ?

Answer 1

if you want to have the content of your text file in a flat manner, you can do something like this:

with open('opad1.txt') as f:
    opady = f.readlines()

dekada = str.join(" ", opady).split()
print(dekada[0])

Answer 2

As the comment suggests, use another level to retrieve just a single item, as the first level just equals a whole list (I added the 'r' as well, for read-mode):

with open('opad1.txt', 'r') as f:
    opady = f.readlines()

dekada = [i.split() for i in opady]

print(dekada[0][0])

Outputs:

4.6
