I want to select part of an array using two conditions.
I know how to do it with one condition (and it works great), but when I use two conditions I get an error message?
This is probably easy, but I cannot figure it out.
Thanks for any help, Mark
>>> a = arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> a[ a>2 ]
array([3, 4, 5, 6, 7, 8, 9])
>>> a[ a>2 and a<8 ]
Traceback (most recent call last):
File "<pyshell#52>", line 1, in ?
a[ a>2 and a<8 ]
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
