[source] -
Trim the leading and/or trailing zeros from a 1-D array or sequence.
Parameters: filt : 1-D array or sequence
Input array.
trim : str, optional
A string with ?f? representing trim from front and ?b? to trim from back. Default is ?fb?, trim zeros from both front and back of the array.
Returns: trimmed : 1-D array or sequence
The result of trimming the input. The input data type is preserved.
Examples
>>> a = np.array((0, 0, 0, 1, 2, 3, 0, 2, 1, 0)) >>> np.trim_zeros(a) array([1, 2, 3, 0, 2, 1])
>>> np.trim_zeros(a, 'b') array([0, 0, 0, 1, 2, 3, 0, 2, 1])
The input data type is preserved, list/tuple in means list/tuple out.
>>> np.trim_zeros([0, 1, 2, 0]) [1, 2]
