How to get first line of a tuple and the third item in its tuple. Need Help, Anybody?

[SukhmeetSingh]

I have these values which I store in a:

a = ((1.425, 4.82145395112958, 0.0656498375731458)
    (1.39716316090366, 7.2, 0.102480129941483)
    (7.425, 4.82145395112958, 0.0656498375731458)
    (7.39716316090366, 7.2, 0.102480129941483)
    (7.425, -0.928546048870416, 0.0656498375731458)
    (7.39716316090366, 0.95, 0.102480129941483)
    (1.425, -0.928546048870416, 0.0656498375731458)
    (1.39716316090366, 0.95, 0.102480129941483))

what I'm doing:

print a[2]

Gives:

Output:
0.0656498375731458
0.102480129941483
0.0656498375731458
0.102480129941483
0.0656498375731458
0.102480129941483
0.0656498375731458
0.102480129941483

I only need this single value to print: 0.0656498375731458

Your sample of a is not a valid tuple in a tuple(missing , seperators), printing a[2] would not give the results shown.

a = ((1.425, 4.82145395112958, 0.0656498375731458),
    (1.39716316090366, 7.2, 0.102480129941483),
    (7.425, 4.82145395112958, 0.0656498375731458),
    (7.39716316090366, 7.2, 0.102480129941483),
    (7.425, -0.928546048870416, 0.0656498375731458),
    (7.39716316090366, 0.95, 0.102480129941483),
    (1.425, -0.928546048870416, 0.0656498375731458),
    (1.39716316090366, 0.95, 0.102480129941483))

print(a[0][2])

would give

Output:
0.0656498375731458

buy the first [0] would get the first tuple and the second [2] would get its 3rd item.

Please, use BBcode as advised.

Hello,

Can you send all code in module, please?
