Legacy fixed-width string functionality

The numpy.char module provides a set of vectorized string operations for arrays of type numpy.str_ or numpy.bytes_. For example

The methods in this module are based on the methods in string

    :toctree:generated/
    equal
    not_equal
    greater_equal
    less_equal
    greater
    less
    compare_chararrays
