numpy.trim_zeros
numpy.trim_zeros(filt, trim='fb')
Trim the leading and/or trailing zeros from a 1-D array or sequence.
import numpy as np
a = np.arange(0, 10)
b = np.zeros((5), dtype=np.int64)
c = np.r_[b, a, b]
print(c) # -> [0 0 0 0 0 0 1 2 3 4 5 6 7 8 9 0 0 0 0 0]
print(np.trim_zeros(c, "b")) # -> [0 0 0 0 0 0 1 2 3 4 5 6 7 8 9]
print(np.trim_zeros(c, "f")) # -> [1 2 3 4 5 6 7 8 9 0 0 0 0 0]
print(np.trim_zeros(c, "fb")) # -> [1 2 3 4 5 6 7 8 9]
