- char.compare_chararrays(a1, a2, cmp, rstrip)#
Performs element-wise comparison of two string arrays using the comparison operator specified by cmp.
- Parameters:
- a1, a2array_like
Arrays to be compared.
- cmp{“<”, “<=”, “==”, “>=”, “>”, “!=”}
Type of comparison.
- rstripBoolean
If True, the spaces at the end of Strings are removed before the comparison.
- Returns:

- ValueError
If cmp is not valid.
- TypeError
If at least one of a or b is a non-string array
Examples
>>> a = np.array(["a", "b", "cde"]) >>> b = np.array(["a", "a", "dec"]) >>> np.char.compare_chararrays(a, b, ">", True) array([False, True, False])
