numpy.c¶
-
numpy.
c_
= <numpy.lib.index_tricks.CClass object>¶ Translates slice objects to concatenation along the second axis.
This is short-hand for
np.r_['-1,2,0', index expression]
, which is useful because of its common occurrence. In particular, arrays will be stacked along their last axis after being upgraded to at least 2-D with 1’s post-pended to the shape (column vectors made out of 1-D arrays).See also
column_stack
- Stack 1-D arrays as columns into a 2-D array.

Examples
>>> np.c_[np.array([1,2,3]), np.array([4,5,6])] array([[1, 4], [2, 5], [3, 6]]) >>> np.c_[np.array([[1,2,3]]), 0, 0, np.array([[4,5,6]])] array([[1, 2, 3, 0, 0, 4, 5, 6]])
