[Numpy-discussion] Working with lists

[Nils Wagner]

Hi all,

I have a list e.g.
>>> bounds
[(1950.0, 2100.0), (1800.0, 1850.0), (1600.0, 1630.0), (1400.0, 1420.0),
(1200.0, 1210.0), (990, 1018.0), (10, 12), (12.0, 14.0), (14.0, 16.0),
(16.0, 18.0), (18.0, 20)]

How can I extract the first value of each pair given in parenthesis i.e.
1950,1800,1600,1400,... ?
