Chris, You can use where() command to find index of a particular number in the array.
For e.g. to find index of number 1 in array a, you can say idx = where(a==1) Regards, Brian -----Original Message----- From: numpy-discussion-boun...@scipy.org [mailto:numpy-discussion-boun...@scipy.org] On Behalf Of Chris Withers Sent: Wednesday, October 06, 2010 5:27 AM To: numpy-discussion@scipy.org Cc: snezana.pe...@glcuk.com Subject: [Numpy-discussion] index of a value in an array Hi All, Given an array such as: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) How can I find the index of a particular number in the array? (ie: if it was a list, I'd do [1,2,3,4].index(3)) cheers, Chris _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
